DR301-95, DR201-95 and DR101-60Digital Hand-held Refractometers

DR201-95 and DR201-95OE

The DR201-95 is a compact digital handheld refractometer which eliminates any user-related reading errors of manual handheld refractometers. Specially developed for fast and easy quality control and process control, it has a widemeasuring range for a refractive index scale and a sugar scale. One DR201-95 can thus often replace several existing instruments. For wine-growing, a special model is available with an Oechsle scale instead of a sugar scale.Both instruments are low-maintenance and are calibrated simply with distilled water. The 1.5 V battery lasts for over 1000 measurements.

DR301-95

DR201-95

DR301-95

The digital handheld refractometer DR301-95 has more functions than a simple handheld refractometer and at the same time is more cost-effective than a desktop unit. Besides the refractive index, sugar and salt scales, up to two other user-defined scales can be programmed. To do this, the handheld refractometer can be connected to a PC via a serial interface.The software supplied with it allows results to bemanaged and printed out. While the instrument canbe operated as a mobile unit with a 9 V block battery, the optionally available power supply unit turns the DR301-95 into a small laboratory refractometer.The sample plate is made of stainless steel and is soflat that it can be cleaned quickly and easily.The instrument is calibrated simply with distilled water and has an optional temperature compensation feature. For incoming goods control applications, an upper and lower tolerance alarm can be entered.

DR101-60

As an entry-level model in digital refractometry, the DR101-60 covers many areas of application where the wide measurement range of the DR201-95 is not required. It offers excellent value for money, in terms of both procurement and operation. Calibration is also with distilled water. The waterproof case allows the DR101-60 to be rinsed under running water.This digital handheld refractometer also has an auto-matic temperature compensation feature, of course. DR101-60

The microscope was invented around 1600 in Holland and continued to be developed from then on. The development of the electron beam microscopes prompted predictions that light microscopes would soon be outdated.However, these predictions proved to be rash. Biologists and medical personnel still appreciate the easy-to-use light microscopes for their natural images and the possibilities offered in observing living tissue.

Composite light microscopes consist of two lens systems: the eye/alignment ocular piece and the tilt/shift adaptor.The objective is the most valuable and most important part of a microscope, as its quality has an enormous influence on a microscope’s all round performance. Achromatic objectives consist of composite lenses made of various materials. This makes it possible to correct an axial chromatic abberation, i.e. a variable focus point of varying wavelengths, relative to two colors. Apochromatic objectives must have apochromatic correction for three colors, while the chromatic abberation of the image’s location in terms of interim colors is very small. If objectives also include curvature correction for the frame (field of vision) they are referred to as plane objectives. The eyepiece has the effect of a loupe and magnifies the intermediate image of the objective. Broad spectrum eyepieces include a higher field-of-vision number than normal oculars. The field-of-vision related figures, multiplied by the ocular magnification, result in an apparent diameter of the microscopic image at a 25 cm distance. In plane ocular pieces, analogous to plane objectives, the field of vision is leveled.

Modern light microscopes are basically grouped into the number of oculars (eye pieces) and objectives in monocular microscopes, binocular microscopes and stereo microscopes.Monocular microscopes have one eyepiece and objective and onetubular lens, and are considered the simplest of microscopes.

Binocular microscopes have two eyepieces and one tubular lens;they facilitate lower physical stress while working, compared to microscopes with one ocular piece, but do not permit a stereoscopic vision of the object.Commonly, in the fields of biology and medicine the light first passes through the object before it enters the objective. This is referred to as transmitted light microscopy. In incident light microscopy the light hits the object from above and is then reflected by the object into the objective.Incident-light microscopy is used for the microscopic study of opaque (non transparent) objects.

Köhler lighting makes it possible to illuminate precisely that area of an objective which is visible to the eye. This prevents any unnecessary light scatter from illuminated parts of the objective which are outside the field of vision.

Dark-field microscopy is used to observe low contrast objects, such as microorganisms or red blood cells. Dark-field microscopy confi-guration guides the light through the specimen at an angle, past the objective. The light, refracted by the object, falls into the objective where it produces a light image in front of a dark background.This is how the contours of otherwise mostly transparent objects or specimens are well visible, while the inner structures are barely visible.

Phase contrast microscopy was developed for microscopy of particularly transparent objects. Transparent objects frequently have higher optical density than the surrounding medium, and therefore offer resistance to the light; hence it is slowed and, relative to the light passing by the object, exits the object in a phase-offset manner.

This phase-offset condition is utilized to form a contrast in brightness. For this purpose a circular aperture is required in the condenser and a phase ring in the objective, which must be coordinated.

Protective atmosphere in food packaging

Ensuring first-class product quality over long periods of time is the goal of food producers. Preservation of taste, colour and freshness of food is obtained through modified atmosphere packaging. An advantage of reducing oxygen is that it inhibits the growth of micro-organisms. Additionally, the oxidation processes which lead to a change of the ingredients into liquid and solid food, are precluded by this method.

Control of modified atmosphere with MAT1500

The gas analyser MAT1500 is used for quality control in the laboratory, in the production sector as well as in the bottling or packaging of perishable foods. In addition to sample checking, the device can also be used to continuously monitor the gas mixture of packaging machines.

Straightforward operation

An ultra-modern LCD display provides a clear and bright picture of all screen content. The integrated touchscreen makes it possible to use the device intuitively and hence quickly, even for non-skilled staff. A solid metal housing with a removable protective cover provides protection against impact and external contamination. After powering on the device, the sample gas is automatically sucked in and the measured values for oxygen (O²), carbon dioxide (CO²) and nitrogen (N²) appear on the display. Only a small sample volume is required to determine the values and a stable measurement value is available already after an average of 10 to 15 seconds. Optionally, measurements can be triggered via a foot-operated switch. This option is particularly useful during mass screening as it enables quick and effortless operation of the MAT1500. Parallel to the O², CO² and N² measurement values, current air pressure, gas flow and measuring chamber temperature are also monitored and shown on the display.

Complete documentation

The complete documentation of all measured values is ensured by an integrated SQL database which stores the last 999 measurements in its data memory. Using flexible filter functions, the measurement data can be displayed at any time or conveniently transferred to a printer, external hard drive or LIMS through an integrated interface (USB, LAN, RS-232). To achieve flexible monitoring of the measurement process by method, batch, product and/or production line including threshold monitoring, up to 100 measuring methods can be installed by the user. Measuring modes, such as minimum or maximum detection, single or permanent measuring, are selected here. The integrated user management system enables the assignment of user rights which are password protected. High measuring accuracy and a broad range of safety functions also ensure the validity of MAT1500.

Different sensors

The gas analysers of the MAT series can be equipped with various sensors for a wide range of product applications. The drift-free and calibration-free oxygen sensor (ZrO²) is highly precise and accurate. Average life of these sensors is approximately 15 years. Alternatively, a cheaper, low-drift, long-life O² EC cell with a service life of three to five years is also available (MAT1100 and MAT1400 models). The low-drift carbon dioxide sensor measures using infra-red technology (NDIR) and is easy to adjust by means of the menu.

Procedure

The sampling location on the packaging is equipped with a self-adhesive septum. Subsequently, the sampling needle is inserted through the septum into the packaging. Measurement commences by pressing a button and the gas mixture is sucked out of the package into the measuring device via the built-in gas pump. Within a short time (usually 10–15 sec.), the residual oxygen and carbon dioxide content in the package is shown on the display and immediately documented in writing, provided a printer is connected. Being fitted with a large number of adjustment options, the device can be optimally tuned in on any kind of product and its special characteristics.

Whatispolarimetry?

If we regard light as an electromagnetic wave propagating through space, it is possible to illustrate the phenomenon of “polarized light”.The oscillation and the direction of propagation of the wave define a very specific plane. If you would look towards the beam you would see this wave as a line which is inclined at a certain angle in space.Regular light includes waves that are inclined in any direction of the space while polarized light is inclined only at a defined angle.This polarization can only be achieved by a very close meshed grating – a polarization filter. This one filters out all waves from the regular light that do not have the same inclination as the filter’s grating. Is the light now directed to a second grating which is exactly 90º to the first grating, no light will fall on the detector or the human eye located behind it. If you place an optically active substance between the two filters, light will again pass through the second filter.Optically active substances change the inclination of the lightwave. Depending on the design of the device, the second filter is rotated (manually or automatically) until no light will fall on the detector. This technical setup explains the terms “optical rotation”, “rotation angle” as well as the terms “clockwise” and “anticlockwise”.The two later terms describe the behavior of the wave mentioned above during the passage through an optically active substance. Depending on the molecular structure of the substance, the direction of the inclination of the wave is towards the right or towards the left.In order to be able to measure this change, the second filter has to be rotated anticlockwise or clockwise.Typical substances are sugar, lactic acid, tartaric acid but also many other biologically active substances.

Optically active are chiral substances whose molecules can take up different spatial arrangements that can not be aligned with by a rotation. Hence, this is a form of configuration isomerism. The different molecules of the substance are called enantiomers.

The following two enantiomers of lactic acid are an example of such a molecule:

The chiral center of the lactic acid is the middle carbon atom. Since the two enantiomers have different rotation angles, the polarimetry will provide information about the molecular structure.In addition to the properties of the substance, thefollowing factors also have an influence on the strength of the optical activity: the temperature, the wavelengthof the light, the concentration of the substance andpossibly also the solvent.The following applies as well: The longer the path of the light through an optically active substance, the larger the angle of rotation.

You’ve lost the key to your locker in the swimming pool. You spot it lying on the bottom of the shallow part of the pool, reach in to take it – and your hand misses.The refraction of light at the boundary of two differentmaterials can be explained as easily as that. If theswimming pool was filled with salt water, the image ofthe key would have been shifted even more.

Light moves at different speeds in materials of different densities. In a vacuum, it reaches 299 792 458 m/s,however in water “only” 225 000 000 m/s.If a ray of light with a defined wavelength strikes a boundary between one medium to another at a fixed angle, the angle of the ray will change according to the refractive indices of the media. Snell’s law describes this phenomenon:

n1∙ sin d1 = n2∙ d2, where d1 is angle a and d2 angle b

Under constant conditions with known material properties, the formula can be manipulated to calculate the refrac-tive index of an unknown second medium. The angle of incidence and angle of refraction can be measured, the refractive index of one of the materials (the prism of therefractometer) is known, and so, after adjusting the formu-la, the refractive index of the unknown material is a matter of simple mathematics. Measurement of the refractive index depends on the tem-perature and wavelength of the light. Determination of the refractive index can provide information on the purity of a substance, but not its exact composition.The refractive index of water at 20 °C is 1.33 nD.Ice has a refractive index of 1.31 nD.Adding sugar to pure water changes the refractive index, depending on the amount added. Adding salt changes the refractive index as well, but in relation to the concentrati-on.This means that if pure water at 20 °C does not have a refractive index of 1.33, it has been “polluted” with some

other material. As a rule, determining the refractive index of a substance is a quick and reliable check of its purity.

Sun flower oil diluted with cheaper oil can be detected just as easily as the sugar content of marmalade during the production process.Another example: cyclohexane at 20 °C has the same refractive index as a 52.9 % sugar solution. This shows that no statements on the composition or possible admix-ture of a substance can be made without knowing exactly what it is.

Temperature is one of the greatest factors which can influ-ence the refractive index. Each substance reacts differently and specifically to temperature.

DR6000Series|DigitalRefractometers

Digital laboratory refractometers from A. KrüssOptronic are setting new benchmarks on many counts. An intuitive touchscreen presents a clear overview of all data and functions and the integrated SQL database stores all data and allows external access via a network or standalone PC.

The refractive index can be a parameter in quantitativeor qualitative analysis and quality assurance. Degreesof polymerisation can also often be monitored frequently, quickly and cost-efficiently without turbidity or the colour of the sample affecting measurement precision.There is no longer any elaborate preparation of samples necessary. The sample is simply placed on the measuring prism and the measurement process is started.The flat stainless steel plate is easy to clean and is highly resistant to aggressive substances.As the refractive index depends on the temperature of the sample, the refractometer should be tempered.The DR6000 series is thus available with integratedelectronic temperature control by means of a Peltierelement. This type of temperature control is faster and more reliable than previous water bath thermostats which can be connected to the digital refractometer without Peltier temperature control. It is thus possible to carry on using an existing thermostat. For continuous measure-ments or series of measurements with many samples and high volumes of samples, devices with flow measurement cells are available. A sample can thus displace the pre-vious one, nonetheless achieving an accurate measure-ment result without cleaning the measuring prism after every measurement. If a printer is connected to the RS-232 interface, the measurement result can be printed out either directly after the measurement or later.All stored measurement data can also be filtered accor-ding to different criteria and exported to a USB stick in .XLS (Excel) or .CSV format.

Fieldsofapplication:

Determination of mixing ratios, qualityand quantity inspection in the following industries:

• Pulp and paper industries • Beverage industry • Food industry • Sugar and sweetener industry • Textiles industry• Pharmaceutical industry• Chemical industry• Petrochemical industry• Metalworking industry• Wastewater management

DR6000 with interfacesfor external Thermostats

The integrated SQL database stores up to 99 user-defined measurement methods and the last 999 measurement results with all relevant data, such as date, time and user.An optional user management system with three authori-sation levels safeguards the settings against any inadver-tant changes. The DR6000 series thus complies with all GLP requirements and is ideally suited for use in FDA-regulated areas. Refractometers can be connected to a PC via an Ethernet interface or integrated in an existing network. If there is access to the Internet, remote mainte-nance and fault diagnostics are also possible. DR6000 refractometers are sturdy, low-maintenance and also extremely quiet - a quality which is often underestimated when it comes to constant use in a laboratory.

AR4

AR4D

The Abbe refractometer was developed in 1869 by Ernst Abbe and is used to determine the refractive index other-wise known as the index of refraction. It is based on the principle of total reflection which occurs at the boundary between the prism and the sample. The refractive index of the prism determines the upper limit of the measure-ment range, as it always has to be greater than that of the sample.To determine the refractive index of solids, a contact liquid with an average refractive index is required.Abbe refractometers are characterised by their easy handling and minimal sample quantities.Samples in the form of solids or pastes can be measured just as easily as liquids. Furthermore, colouration or clouding scarcely affect the measurement result.Besides the refractive index, the solid content can be determined in %Brix.The refractive index of a sample depends on the wave-length of the light used in measurement. That is why we supply our AR4 and AR4D with LED illumination for the measuring prism. This has the standard wavelength of 589 nm and has a very long service life (>100,000 h). Refractometers also have scale illumination.The refractive index also depends on temperature.As the temperature increases, the refractive index drops. That is why our Abbe refractometers have thermostat connections on both the illumination prism as well as the measurement prism. A digital thermometer is included in the scope of supply.Our Abbe refractometers can easily be checked and ca-librated with the calibration plates provided and comply with all requirements of ASTM D1218.

PR21|ProcessRefractometer

The process refractometer was developed for direct installation in pipelines and boilers, and is ideal for process monitoring, control and separation of products in the chemical, beverage, food, pulp and paper as well as sugar industries. As no bypass is necessary, it is much simpler to install the process refractometer in a pipeline or tank.

Standard connections enable the process refractome-ter to be assembled quickly and easily.Depending on diameter, a T-piece is inserted into the pipeline or an adapter welded on, as with the tank.

PRB21|BypassProcessRefractometer

The bypass process refractometer PRB21 fills the gap between the DR6000 series of digital laboratoryrefractometers and the process refractometer PR21.The sample is directed through a bypass to themeasurement chamber which is made of stainless steel,while the actual prism is made of sapphire and is thus particularly scratch-resistant. The PRB21 is usually connected to a PLC and is used for continuous process monitoring. The measurement interval is adjustable (>3 s) and the measurement result is not affected by either the colour or the turbidity of the sample. The PRB21 has various interfaces and can also be supplied with PROFIBUS on request.A display is also available for visual monitoring.The internal temperature sensor allows automatictemperature compensation and the measuredtemperature to be sent to the PLC.

ER60-Serie|GemRefractometers

ER601Illumination not figured


Gemstone refractometers are used for the classification and quality control of gemstones. The gemstone to be examined is simply placed on the prism with a drop of contact fluid. The refractive index of the gemstone is read through the ocular of the refractometer. The refractive index is an important parameter in classifying a mineral or gemstone. Each mineral has its typical refractive index, due to its chemical composition and crystalline structure. Our gemstone refractometers are characterised by their particularly sharp image and good readability.With the sodium filter that only lets through light with a wavelength of 589 nm, the refractometer can be used as a mobile unit with an ordinary light source or withsufficient ambient lighting. LED illumination is also available with a wavelength of 589 nm.

HistoryofA.KRÜSSOptronic

200 years – a long time for a company’s history. The family enterprise of A. Krüss has invested this time to keep up with the breathtaking developments in science,technology, optics and precision engineering.

An amazing number of high-precision optical and other quite different products have been shipped world-wide from the Hamburg laboratories. Although some have long since been forgotten, more recent products, are known throughout the world.

But let us return to the origins, to 1796 and the Hamburg workshop of EdmundGabory, „Mechanicus Opticus“.

Gabory was trained in London by none other than Jesse Ramsden, the world famous optician, at a time when precision engineering was flourishing. On finishing histraining in1790, Edmund set up a workshop of his own in London Holborn.In 1796 he moved with his family to Hamburg, the international portcity and trading centre. This is where the talented optical engineer established his career and saw his business prosper. In 1813 Gabory died. The company was taken over by his widow Mary and their son Edmund Nicolas. In 1823 Gabory’s daughter Mary Ann married Andres Krüss.

The combination of scientific skill with Hanseatic business acumen, tradition and perspective proved to be a successful formula. Together with his wife and her brother, Andres Krüss led the company to further success, adding nautical instruments and charts to their product range. Brisk trade with the neighbouring Scandinavian and other foreign countries developed. In 1844 Andres Krüss established a company of his own named Optical Institute A. Krüss. Four years later he fell victim to one of the cholera epidemics. After his death, the company was first run by his widow who then handed it over to her sons Edmund and William in 1851.

In 1859 Edmund set up the company’s own lens-grinding facility. In addition tocamera lenses, they later manufac-tured projectors for dissolving views.In order to demonstrate the quality of his photographic lenses he opened his ownphotographic studio. He was awarded first prize for his lenses at the World Exhibitionin London in 1862. In 1865 Krüss patented his famous Magic Lantern, forerunner of the cinema projector.

Still in existence at this time, the original company of Edmund Gabory was merged with Optical Institute A. Krüss in 1886. After completing his training with distinction at Stein-heil and his university studies in Munich, Edmund’s son Hugo returned to take over the management of the company in 1888. In a period of many new inventions and scien-tific developments, Dr. Hugo Krüss established himself as a pioneer in theoretical and applied photometry. His Manual of Electromechanical Photometry became a standard work. In his capacity as chairman of the German Society for Precision Engineering and Optics, Dr. Krüss was appointed by the German government as an expert for customs and excise in 1892; while in office, he convinced the government to establish a tariff heading specifically for „scientific instruments“. In 1917 the Hamburg Senate awarded Dr. Krüss a professorship in recognition of his achievements in the scientific world and his engagement in public affairs.

In 1904 Hugo’s son, Dr. Paul Krüss joined the family company at the age of only 24. The so-called „master craftsman with a doctorate“ managed the company from 1920 during the troubled times of crisis and World War as well as during the later re-structuring of the German economy. Using his international connections in the world of science, he developed a range of scientific instruments including laboratory equipment for schools.

Andres Krüss, Paul’s son, was an engineer and became a partner in 1946 in the 6th generation. Due to his hard work during the „German Economic Miracle“, Andres secured new customers and new markets. Dr. Paul Krüss died in 1976 at the age of 96. No one else had ever run the company so long.

Today the company is run in the 7th generation by Martina Krüss-Leibrock, who took over A. KRÜSS Optronic in 1980. Martina is the daughter of Andres who died in 1992. In 2005 Martinas daughter Karin Leibrock joined the management of the company in the 8th generation. And today the company A. Krüss remains famous for high-precision, state-of-the-art measuring instruments. Thus the traditional craftsman’s art of precision engineering has been perfectly combined with innovative electronic technology.

A.KRÜSS OPTRONIC REFRACTOMETERSWHAT IS REFRACTOMETRY?

You’ve lost the key to your locker in the swimming pool. You spot it lying on the bottom of the shallow part of the pool, reach in to take it – and your hand misses.The refraction of light at the boundary of two differentmaterials can be explained as easily as that. If theswimming pool was filled with salt water, the image ofthe key would have been shifted even more.

Light moves at different speeds in materials of different densities. In a vacuum, it reaches 299 792 458 m/s,however in water “only” 225 000 000 m/s.If a ray of light with a defined wavelength strikes a boundary between one medium to another at a fixed angle, the angle of the ray will change according to the refractive indices of the media. Snell’s law describes this phenomenon:

n1∙ sin δ1 = n2∙ sin δ2, where δ1 is angle α and δ2 is angle β

Under constant conditions with known material properties, the formula can be manipulated to calculate the refractive index of an unknown second medium. The angle of incidence and angle of refraction can be measured, the refractive index of one of the materials (the prism of the refractometer) is known, and so, after adjusting the formula, the refractive index of the unknown material is a matter of simple mathematics. Measurement of the refractive index depends on the temperature and wavelength of the light. Determination of the refractive index can provide information on the purity of a substance, but not its exact composition.

The refractive index of water at 20 °C is 1.33 nD.Ice has a refractive index of 1.31 nD.Adding sugar to pure water changes the refractive index, depending on the amount added. Adding salt changes the refractive index as well, but in relation to the concentration. This means that if pure water at 20 °C does not have a refractive index of 1.33, it has been “polluted” with some other material. As a rule, determining the refractive index of a substance is a quick and reliable check of its purity.

Sun flower oil diluted with cheaper oil can be detected just as easily as the sugar content of marmalade during the production process.

Another example: cyclohexane at 20 °C has the same refractive index as a 52.9 % sugar solution. This shows that no statements on the composition or possible admixture of a substance can be made without knowing exactly what it is.

Temperature is one of the greatest factors which can influence the refractive index. Each substance reacts differently and specifically to temperature.

DR6000 SERIES | DIGITAL REFRACTOMETERS

Versatile and powerful!

Digital laboratory refractometers from A. Krüss Optronic are setting new benchmarks on many counts. An intuitive touchscreen presents a clear overview of all data and functions and the integrated SQL database stores all data and allows external access via a network or standalone PC.

The refractive index is a parameter in quantitative or qualitative analysis and quality assurance. Degrees of polymerisation can also often be monitored frequently,quickly and cost-efficiently without turbidity or the colourof the sample affecting measurement precision. There is no longer any elaborate preparation of samples necessary. The sample is simply placed on the measuringprism and the measurement process is started.

The flat stainless steel plate is easy to clean and is highlyresistant to aggressive substances. As the refractive index depends on the temperature of the sample, the refractometer should be tempered. The DR6000 series is thus available with integrated electronic temperature control by means of a Peltier element. This type of temperature control is faster and more reliable than water bath thermostats. For continuous measurements or series of measurements with many samples and high volumes of samples, devices with flow measurement cells are available. A sample can thus displace the previous one, nonetheless achieving an accurate measurement result without cleaning the measuring prism after every measurement.

The DR6000 series of refractometers are robust, low-maintenance and also very quiet - an often underestimated quality for equipment used continuously in a laboratory.

An integrated SQL database stores up to 99 user-defined measurement methods and the last 999 measurement values with all associated data. You can select the stored results by means of various filters and export data in

XLS- or CSV-format on a USB flash drive, print directlyor convert to a PDF document for printing from a PC.By connecting a printer to the RS-232 interface, results can be printed out as soon as they are measured.

The refractometer can be connected to a PC or linked to a network via an Ethernet interface. If there is access to the Internet, remote maintenance and fault diagnosis are also possible.

Optional user management functionality with three authorisation levels protects the settings from being chan-ged unintentionally. The DR6000 series thus meets all GLP requirements and is best suited for use in FDA-regulated situations.

Special KrüssLab software also enables the instrument to be controlled from a PC. This exactly replicates the intuiti-ve touchscreen of your Krüss unit, allowing you to “ope-rate” it directly from the PC. Measured values are copied from the device into the KrüssLab database. You then have permanent access to more than the last 999 results. This data can be accessed even when the Krüss unit is switched off.The refractometers in this series meets the guidelines of ASTM D1218 and D1747.

Automated sample injector - Autosampler

AS80The refractometer, fitted with a flow-through cuvette, and the density meter can be completed by means of an automated sample injector system.This consists of a rotor sampler, a peristaltic pump and a constriction-tube valve as toggle switch. The sampler uses a plate with 89 positions for sample tubes in polystyrene withdimensions Ø 16 x 100 mm. These can accept sample volumes of 8 ml. Peristaltic pump and valve are integrated into the sampler and are controlled via this by the measuring device. The heads of the two assemblies are situated on the right-hand side of the unit.The sample is transported into the measurement system by means of the peristaltic pump. If the measured value is stable and is recorded, the valve toggles from Sample to Standby and the system is rinsed. This minimises spreading andmeasurement errors. To take the following measurement the rotor is moved to the next sampling position and the valve set back to sample mode.

F-Model: with flow cell

The flow cell is a variation of the DR6000 series and is indicated by the suffix “F” (e.g. -F, -TF). It consists of a measuring cell cover fixed with robust stainless steel brackets over the prism, with two tubes for inflow and outflow. All parts that come into contact with the sample (tubes and measuring cell cover) are made of PTFE (Teflon). Combined with the sapphire prism equippedwith a Peltier thermostat, precise and stable temperature control is assured. The UNF-thread hose coupling ismade of PEEK.

The flow cell allows the unit to run in automated mode using a peristaltic pump or autosampler. It can also be filled by means of injection if required. Thanks to its special geometry (forced venting), no air bubbles can become trapped.

As a result of the small size of the micro-measuring cell, this version is particularly suitable for applications in which it is important for samples to be in small volumes (e.g. in the flavourings industry).The measuring cell can be removed easily and the sample thus placed directly on to the prism.

AR | ABBE REFRACTOMETERS

The modern classic!

The Abbe refractometer was developed in 1869 byErnst Abbe and is used to determine the refractive index otherwise known as the index of refraction.It is based on the principle of total reflection which occurs at the boundary between the prism and the sample. The refractive index of the prism determines the upper limit of the measurement range, as it always has to be greater than that of the sample.With the AR Series, Krüss has two models of the Abbe refractometer in its range. These are easy to use and require only a small sample volume. These devices allow samples in the form of solids or pastes to be mea-sured just as easily as liquids. Furthermore, colouration or clouding scarcely affect the measurement result. Besides the refractive index, the solid content can be determined in %Brix. To determine the refractive index of solids, a contact liquid with an average refractive index is required.The refractive index of a sample is dependent on the wavelength of the light used for the measurement andon the temperature. As the temperature increases, the refractive index drops. That is why our Abbe refractometers have thermostat connections on both the illumination prism as well as the measurement prism.

AR2008 | DIGITAL ABBE REFRACTOMETER

The digital Abbe refractometer AR2008 has an electronic data processing system. The refractive index or Brix value is shown on an LCD display together with the temperature.A serial interface allows measured values with date and time to be transferred directly to the PC or printer.An automatic temperature compensation feature is optionally selectable.The AR2008 has a thermostat connection for prisms and a built-in light source (589 nm) for the measuring prism.The AR2008 is extremely sturdy and is ideally suited for use in a harsh environment.It is supplied with a glass calibration plate, contact fluid and a screwdriver as well as a dust hood.

AR4 | ANALOGUE ABBE REFRACTOMETER

The AR4 offers readings via ocular. It has an adjustable scale, temperature controlled prisms, and thermostat connections for prisms.The refractive index of a sample depends on the wavelength of the light used in measurement.That is why we supply our AR4 with LED illumination for the measuring prism. This has the standard wavelengthof 589 nm and has a very long service life (>100.000 h).Refractometers also have scale illumination.Since the refractive index is also temperature-dependent, our Abbe refractometers feature thermostat points on both the lighting and the measurement prisms.A digital thermometer is supplied. Other wavelengths are available on request.Our Abbe refractometers can easily be checked and calibrated with the calibration plates provided and comply with all requirements of ASTM D1218.

PR21 SERIES | PROCESS REFRACTOMETER

PR | PROCESS REFRACTOMETER

Complete quality control!

Process refractometers are built directly into pipework and boilers or operated in the bypass. They are ideal for process monitoring, control and product separation in a variety of industries (chemicals, beverages, food and sugar).

Why use Refractometers in pipelines?The monitoring of refractive index is a popular method of inline quality control in many process industries, including pulp and paper, food and beverage, chemical andpharmaceutical, and wastewater. It provides real-time data for quality control and Good Manufacturing Practice (GMP), and can be used to monitor qualities such as concentration of a solution, density of a fluid, or % Brix.An inline process refractometer is installed directly into pipework or a boiler, with standard connections for easy assembly. The alternative bypass process refractometer analyses a stream of fluid drawn off the main process run.

As no bypass is necessary, it is much simpler to installthe process refractometer in a pipeline or tank.Standard connections enable the process refractometerto be assembled quickly and easily. Depending on diameter, a T-piece is inserted into the pipeline or an adapter welded on, as with the tank.Three interfaces are available for this unit:Analogue 0/4-20 mA, Ethernet, or PROFIBUS.

Model overview

The bypass process refractometer PRB21 fills the gapbetween the DR6000 series of digital laboratoryrefractometers and the process refractometer PR21.The sample is fed into the measurement chamber through a stainless steel bypass. The prism is made of particularly scratch-resistant sapphire.The PRB21 is generally connected to a PLC and provides continuous process control. Small sample volumes suffice for this. The measurement interval is adjustable (>3 s) and the measurement result is not affected by either the colour or the turbidity of the sample.

The PRB21 has various interfaces and can also be supplied with PROFIBUS on request. A display is also available for visual monitoring. Automatic temperature compensation can be obtained by means of the internal temperature sensor and the measured temperature fed to the PLC.

ER60 SERIES | GEM REFRACTOMETERS

Real or not?!

Gemstone refractometers are used for the classificationand quality control of gemstones. The gemstone to beexamined is simply placed on the prism with a drop ofcontact fluid. The refractive index of the gemstone is read through the ocular of the refractometer. The refractive index is an important parameter in classifying a mineral or gemstone. Each mineral has its typical refractive index, due to its chemical composition and crystalline structure. Our gemstone refractometers are characterised by their particularly sharp image and good readability. With the sodium filter that only lets through light with a wavelength of 589 nm, the refractometer can be used as a mobile unit with an ordinary light source or with sufficient ambient lighting. LED illumination is also available with a wavelength of 589 nm.

The History of A. KRÜSS Optronic 10

Precision Instruments „made in Germany“For over 200 years A.Krüss Optronic has been famous worldwide for innovative optic-electronic measuring instruments of the highest precision.As the oldest company in this field, our target is to develop instruments which set new standards.With our products we aim to simplify testing and inspection tasks in laboratories or production facilities.For this reason all instruments are user-friendly and can be operated intuitively.

What is digital density measurement using the oscillatingU-tube principle?The example of a tuning fork shows that by applying a mecha-nical impulse one can generate a sound with a characteristic pitch. This sound is the result of the oscillation created by deflecting the prongs of the tuning fork. A determining factor in the pitch of the note obtained, and thus of the oscillating frequency, is the mass of the tuning fork.Digital density measurement puts this relationship to use by means of the U-tube oscillation principle. The extremely fine capillaries are made to oscillate by a piezoelectric or magnetic transducer with a characteristic frequency.The resulting resonant frequency of the U-tube will depend on the mass of the filled sample. This frequency can be measured very accurately and used to calculate the density of the sample.The physical relationship of oscillation frequency (the reciprocal of the period of oscillation) to density is very simple and linear. Accordingly, calibration is only possible with two standards as a rule - air and water.

What is density?Density ρ is a characteristic property of materials and indicates the relationship of mass m to volume V.

It is measured in g/cm³ or kg/m³.

For high-precision measurements, the most significant influencing factor is the temperature of the sample.It is essential therefore that modern density meters are equipped with efficient temperature control of the measure-ment room.

A temperature change of 0.1 °C consequently has an influence on density of between 0.1 and 0.3 kg/m3,depending on the substance.

Density measurement is often also used for determining the concentrations of mixtures of fluids. Strictly speaking, this applies to mixtures of two substances, also known as binary systems. Extensive concentration tables can becreated in DS7800 for our customers to facilitate everyday measurements. However, digital density measurement can also be of significant benefit in analysing complex solutions such as beer or fruit juices.

Relationship of density to temperature

What are the advantages of digital density measurement?Today there are still two alternative procedures for measuring density commonly in use.The areometer, better known as a hydrometer, works on the Archimedean principle of buoyancy in proportion to mass. An areometer is low-cost but difficult to read, particularly in highly viscose or dark samples.Additionally, large sample volumes of at least 100 ml are required. A high degree of precision (max. 0.001 g/cm3) requires precise temperature regulation. The pycnometer provides a gravimetric determination of density. This can achieve higher degrees of precision than the hydrometer. Owing to complex weighing procedures, however, measurement by this method can take hours and requires trained personnel.The advantages of density measurement using the oscillating U-tube include both good repeatability and high precision. These devices are easy to use and enable measurements to be made simply in a matter of minutes at a defined, regulated temperature.

DS7800 | Density Meter

Digital density meters with up to five decimal places for measuring density, relative density and concentration of aqueous solutions in a range of 0.0000 – 1.9999 g/cm³.Measuring method is based on established oscillating U-tube technology. The U-tube made of glass is moni-tored through the window to ensure that no gas bubble falsifies measurement results.

The device has a high-precision recirculation air-temperature control based on a Peltier element.Calibration is performed with pure water and dry air.A dry-air unit and a peristaltic pump for samplehandling are included.Tubing material is also optionally available in achemical resistant design. Injection filling, e.g. forhigher viscosity specimens, is also possible.

An integrated SQL database stores up to 99 user-defined measurement methods and the last 999 measurement values with all relevant data, such as date,time and user. You can select the stored results bymeans of various filters and export data in XLS orCSV format on a USB flash drive, print directly orconvert to a pdf document for printing from a PC.

AS80The refractometer, fitted with a flow-through cuvette,and the density meter can be completed by means of an automated sample injector system. This consists of a rotor sampler, a peristaltic pump and a constriction-tube valve as toggle switch. The sampler uses a plate with 89 posi-tions for sample tubes in polystyrene with dimensionsØ 16 x 100 mm. These can accept sample volumes of8 ml. Peristaltic pump and valve are integrated into the sampler and are controlled via this by the measuringdevice. The heads of the two assemblies are situatedon the right-hand side of the unit.The sample is transported into the measurement systemby means of the peristaltic pump. If the measured valueis stable and is recorded, the valve toggles from Sample to Standby and the system is rinsed. This minimises spreading and measurement errors. To take the following measure-ment the rotor is moved to the next sampling position and the valve set back to sample mode.

The History of A. Krüss Optronic

200 years of history is a long time for any company. The family enterprise of A. Krüss has spent this long keeping up with, and ahead of, some breathtakingdevelopments in science, technology, optics andprecision engineering.

An amazing number of high-precision optical and other quite different products have been shipped worldwide from the company’s Hamburg laboratories.Although some have long since been forgotten, many are known throughout the world. But let us return to the origins, to 1796 and the Hamburg workshop of Edmund Gabory, "Mechanicus Opticus".

Gabory was trained in London by none other than Jesse Ramsden,theworldfamousoptician,atatimewhenprecision engineering was flourishing. On finishing his training in 1790, Edmund set up a workshop of his own in London’s Holborn. In 1796 he moved with his family to Hamburg, the international port and trading city.This is where the talented optical engineer establishedhis career and saw his business prosper.In 1813 Gabory died, and the company was taken over byhiswidowMaryandtheirsonEdmundNicolas.In 1823 Gabory’s daughter Mary Ann marriedAndres Krüss.

The combination of scientific skill and Hanseatic busi-ness acumen, tradition and perspective proved to be a successful formula. Together with his wife and herbrother, Andres Krüss led the company to furthersuccess, adding nautical instruments and charts to their product range. Brisk trade with the neighbouring Scan-dinavian and other foreign countries developed.In 1844 Andres Krüss established a company of his own named Optical Institute A. Krüss. Four years later he fell victim to one of the cholera epidemics.After his death, the company was first run by his widow who then handed it over to her sons Edmund andWilliamin1851.

In 1859 Edmund set up the company’s own lens-grinding facility. In addition to camera lenses, they later manufactured projectors for dissolving views.In order to demonstrate the quality of his photographic lenses, he opened his own photographic studio. He was awardedfirstprizeforhislensesattheWorldExhibitionin London in 1862. In 1865, Krüss patented his famous Magic Lantern, forerunner of the cinema projector.

Still in existence, the original company of Edmund Gabory was merged with Optical Institute A. Krüss in 1886. After completing his training with distinction at Steinheil and his university studies in Munich, Edmund’s son returned to take over the management of the

company in 1888. In a period of many new inventions and scientific developments, Dr. Hugo Krüss established himself as a pioneer in theoretical and applied photo-metry. His Manual of Electromechanical Photometry became a standard work. In his capacity as chair-man of the German Society for Precision Engineering and Optics, Dr. Krüss was appointed by the German government as an expert for customs and excise in 1892; while in office, he convinced the government to establish a tariff-heading specifically for ‘scientific instruments’. In 1917, the Hamburg Senate awarded Dr. Krüss a professorship in recognition of his achieve-ments in the scientific world and his engagement in public affairs.

In 1904 Hugo’s son, Dr. Paul Krüss, had joined the family company at the age of only 24. The so-called ‘master craftsman with a doctorate’ managed the com-pany from 1920 during the troubled times of crisis and WorldWar,aswellasduringthelaterrestructuringofthe German economy. Using his international connec-tions in the world of science, he developed a range of scientific instruments including laboratory equipment for schools.

Andres Krüss, Paul’s son, was an engineer and be-came a partner in 1946 in the 6th generation.Due to his hard work during the ‘German Economic Miracle’, Andres secured new customers and newmarkets. Dr. Paul Krüss died in 1976 at the age of 96. Nooneelsehadeverrunthecompanysolong.

Today the company is run in a seventh generation by Martina Krüss-Leibrock, who took over A. Krüss Op-tronic in 1980. Martina is the daughter of Andres, who died in 1992. In 2005, Martina’s daughter Karin Leibrock joined the management of the company as 8th generation, and today the company remains famous for high-precision, state-of-the-art measuring instruments.The traditional craftsman’s art of precision engineering has been perfectly combined with innovative electronic technology.

Whatispolarimetry?

If we regard light as an electromagnetic wave propagating through space, it is possible to illustrate the phenomenon of “polarized light”.The oscillation and the direction of propagation of the wave define a very specific plane. If you would look towards the beam you would see this wave as a line which is inclined at a certain angle in space.Regular light includes waves that are inclined in any direction of the space while polarized light is inclined only at a defined angle.This polarization can only be achieved by a very close meshed grating – a polarization filter. This one filters out all waves from the regular light that do not have the same inclination as the filter’s grating. Is the light now directed to a second grating which is exactly 90º to the first grating, no light will fall on the detector or the human eye located behind it. If you place an optically active substance between the two filters, light will again pass through the second filter.Optically active substances change the inclination of the lightwave. Depending on the design of the device, the second filter is rotated (manually or automatically) until no light will fall on the detector. This technical setup explains the terms “optical rotation”, “rotation angle” as well as the terms “clockwise” and “anticlockwise”.The two later terms describe the behavior of the wave mentioned above during the passage through an optically active substance. Depending on the molecular structure of the substance, the direction of the inclination of the wave is towards the right or towards the left.In order to be able to measure this change, the second filter has to be rotated anticlockwise or clockwise.Typical substances are sugar, lactic acid, tartaric acid but also many other biologically active substances.

Optically active are chiral substances whose molecules can take up different spatial arrangements that can not be aligned with by a rotation. Hence, this is a form of configuration isomerism. The different molecules of the substance are called enantiomers.

The following two enantiomers of lactic acid are an example of such a molecule:

The chiral center of the lactic acid is the middle carbon atom. Since the two enantiomers have different rotation angles, the polarimetry will provide information about the molecular structure.In addition to the properties of the substance, thefollowing factors also have an influence on the strength of the optical activity: the temperature, the wavelengthof the light, the concentration of the substance andpossibly also the solvent.The following applies as well: The longer the path of the light through an optically active substance, the larger the angle of rotation.

HR-Serie|ManualHand-heldRefractometers

Manual handheld refractometers are for fast everyday use. They are particularly easy to use and very sturdy.Various scales and additional functions ensure that there is exactly the right handheld refractometer for manyapplication areas. This makes for reliability when rea-ding, as the measured value does not first have to be converted.

Some models have an automatic temperature compen-sation feature. which increases measurement precision for measurements which are performed at 10–40 °Cinstead of 20 °C. For calibration, distilled water isrequired, or else a small calibration plate is provided.
