Greetings,

On May 24, 2004 Don Brookfield Sr., founder, mentor,

inventor and leader of Brookfield Engineering

Laboratories passed away. His inventions and his

Company have enjoyed 70+ years of success to the

point where they have become the world standard for

viscosity measurement. The reasons for this are very

important to recognize.

Don was a consummate engineer. He was a

perfectionist who believed that his products could

always be improved no matter how successful they

were. He had an abiding desire to support and service

his customers to a degree that often caused him to lose

money rather than have a dissatisfied customer. Don

believed that for a business to have a future it must

never take advantage of its market position, never

overcharge its customers, and always provide excellent

service at very reasonable cost. He liked to say “if you

give the customer the best value, they will come back

to you over and over again”.

Don imbedded these ideals into the culture of

Brookfield, and we continue to honor the legacy

of Donald W. Brookfield, Sr. by maintaining and

reinforcing those ideals. Quality, customer support and

peerless value for your money, all are paramount in the

way Brookfield does business. As CEO I am committed

to furthering those attitudes, because I always want

our customers to think of Brookfield as “quality, service

and value”. I know my father would agree.

David Brookfield,

President

Brookfield introducesthe DV-III Ultra

Brookfield’s top of the line rheometer combines the sophisticated viscosity test capability of the DV-III+ Rheometer with the yield stress measurement capability of the YR-1 Yield Rheometer. Twice the instrument, one great price. See pages 18 and 19 for complete information.

Brookfield enhances the LFRA Texture Analyzer

with improved test capabilities for QC & R&D

Brookfield has redesigned the world standard Steven’s LFRA Texture Analyzer, combining simplicity of operation with increased load capacity and expanded test flexibility. In stand-alone mode, the LFRA provides increased test method choices, better resolution and improved accuracy. An automatic Bloom test option facilitates analysis for our established gels and gelatin markets. Expanded testing, including Texture Profile Analysis, is available via our Excel based software, enabling the technologist to generate analytical data comparable to other more costly instruments.For complete information regarding this exciting development, turn to pages 66 and 67.

3. How much sample is available for testing?

4. Is temperature measurement/control necessary?

5. How will you record the viscosity data?

1. What is the viscosity range of your material: Low, medium, high?

2. What rotational speeds or shear rates are important?

The ability to gather data on a material’s viscosity behavior gives manufacturers an important “product dimension.” Knowledge of a material’s rheological characteristics is valuable in predicting its pourability, its performance in a dipping or coating operation, or the ease with which it may be handled, processed, or used. The interrelation between rheology and other product dimensions often makes the measurement of viscosity the most sensitive or convenient way of detecting changes in color, density, stability, solids content, and molecular weight.

Ease of use, flexibility, reliable performance and quality of service have made Brookfield Viscometers favorites all over the world. All Brookfield Viscometers are accurate within ±1.0% of the range in use and have a reproducibility within ±0.2%. Test results can be duplicated anywhere in the world when the same model instrument is used.

Why Choose Brookfield?

Why Measure Viscosity?

Questions to Consider

Brookfield also offers several special purpose instruments which are used to perform a specific type of test or are used to evaluate certain types of materials.

The Model Selection Table (shown at right) shows detailed information on standard Brookfield Viscometers/Rheometers, including the Dial Reading, DV-E, DV-I+, DV-II+Pro, and DV-III+. There may be industry or supplier/vendor specifications that you need to duplicate. Before making a final selection, we suggest that you confer with people in your industry to find out which Brookfield Viscometer they are usingso that your data can be correlated.

In addition, you may wish to call us and discuss your application or refer to our extensive library of technical papers which covers a complete spectrum of applications. We can also test your materialsat Brookfield to recommend the instrument most suitable foryour application.

The Selection Method

Standard Brookfield Viscometers/Rheometers are supplied witha standard spindle set constructed of stainless steel (#302). Additional spindle options are available in #316 stainless steelor with teflon coating for increased corrosion resistance.

Cylindrical SpindlesCylindrical spindles are particularly valuable when measuring non-Newtonian fluids and are applicable to any Brookfield Viscometer model with the use of appropriate range tables. Cylindrical spindles may be substituted for standard spindles upon request.

Spindles

Extensions/Quick Connects

Type D ExtensionsUsed for applications where the depth of spindle immersion can be observed. Can also be used without a link for rapid spindle change.

Quick Connect CouplingUsed with disc, cylindrical and T-bar spindles for quick and easy attachment of the spindle to any standard Brookfield Viscometer/Rheometer.

Software Requirements

“Loader” programs are supplied with the DV-II+Pro Viscometer or DV-III Ultra Rheometer and allow a computer to download measurement parameters into the instrument. The computer can then be disconnected, leaving the instrument programmed with your custom parameters. DVLoader™ and RheoLoader™ are shown below.

The Wingather™ data collection program for use with the DV-II+Pro collects data via a PC. The results can be graphed and plots overlaid for historical comparisons. Wingather does not offer computer control.

Control and Analysis software is used to perform automated, comprehensive testing as well as analysis on the data collected. Rheocalc32™ for the DV-III Ultra Rheometer and DV-II+Pro Viscometer, Capcalc32™ for the CAP2000+, Rheo2000™ for the R/S Rheometer and Rheovision™ for the PVS Rheometer are exclusive Brookfield Software products designed to save time and enhance measurement results.

COMPUTER TYPE: Pentium™ III or higher 256 MB RAM

OPERATING SYSTEM: Windows 98™/2000 ™, NT™, or XP™ (not compatible with Mac OS, UNIX or Linux)

COLOR/GRAPHICS: VGA graphics card and monitor

DV Loader for the DV-II+ Pro ViscometerThis performance parameter software is supplied with the DV-II+Pro Viscometers. DV Loader is a software program that allows specific choices of parameters to be downloaded into your viscometer. It’s simple: 1. Connect your DV-II+Pro to a PC. 2. Create a custom test program on your PC. 3. Use DV Loader to download your test parameters for speed, test duration, etc. to the instrument. 4. Disconnect the DV-II+Pro from your PC. Now you have secure, user defined test methods in your viscometer that are set-up to run tests for your particular applications.

RheoLoader for the DV-III Ultra RheometerCustomize your test preferences for DV-III Ultra Rheometers. This exclusive Brookfield software, supplied with the DV-III Ultra, allows you to create customized programs for your instrument, each with as many as 50 commands. Once a program is downloaded from a host computer, comprehensive viscosity tests can be run automatically in stand-alone mode.

Software for our new line of texture measurement instrumentation is shown on page 34.

29

Wingatherfor the DV-II+PRO Viscometer

This data collection and graphing software provides an easy means to gather tabular data, graph and plot that data, and create permanent test records for analysis. Use Brookfield’s Wingather application software to collect, analyze or record test data in any of five different modes:Manual – A data point is taken when the operator chooses

Vari-Speed – A data point is taken when the operator changes the viscometer speed

Timed Stop – A data point is taken at an operator defined time interval.

Timed Torque – Data is taken at an operator defined time interval until an operator defined % torque value is reached.

Spring Relaxation – Data is taken at an operator defined time interval as the spindle “unwinds” (motor off condition).

Data is output directly to your PC. The data can easily be graphed. Overlay plots showing multiple sets of test data are possible.

Automates data collection to save time

Reduces potential operator error when recording data

Create viscosity flow curves (rheograms) and a permanent record of each test

Up to six data sets may be plotted and overlaid for product comparisons

Viscosity plots can be configured vs. time, temperature, shear rate, and shear stress

Data can be saved as a Wingather file (Paradox Database) or exported to Excel format

Math modeling for yield stress calculations (Bingham Plastic, Casson, Power Law, IPC Paste analysis)

Features& Benefits

30

Rheocalc32for the DV-III Ultra Rheometer & DVII+Pro Viscometer

Automate your sample testing for maximized accuracy, reliability and work efficiency.

Brookfield’s powerful Rheocalc32 application software empowers your DV-III Ultra Rheometer/DV-II+Pro Viscometer to provide fully automated and highly sophisticated testing. Rheocalc32 over-rides the instrument’s internal firmware and allows a dedicated computer

to control the instrument so other work can be done while the tests are running. After testing is complete, Rheocalc32 can analyze that data, generate multiple plot overlays to compare test studies, print tabular data, run math models for comparative “fit” analysis, and perform other important time-saving routines.

Powerful scripting language provides for simple to complex data collection programs

Provides looping functions for repetitive tasks

Built-in visual prompts for selecting spindle geometry, speed, shear rate, etc.

Automates data collection to save time and eliminate operator error

Provides instantaneous viscosity flow curves (rheograms) and creates a permanent record

Thermosel™for Elevated Temperature Testing

Sample Container

Thermo Container (Heating Chamber)

Programmable Temperature Controller

The difficulty with viscosity measurements of hot melts and liquids at elevated temperatures has been in maintaining accurate temperature control that is consistent from sample to sample so that meaningful data could be obtained.

The Brookfield Thermosel solves this problem by providing a stable, precisely controlled sample environment. This, together with the inherent accuracy of the Brookfield Viscometers, is fundamental to the Thermosel System, which produces viscosity measurements that are not only accurate but entirely reproducible.

Several factors contribute to the stable environment:

Non-fluctuating temperature control

Small sample volume and insulated sample chamber which reduces temperature gradients within the sample

The rotating spindle, which acts as a built-in stirring device

The test procedure is quite straightforward. Once familiar with the system, unskilled operators can easily produce accurate, reproducible data.

IES Small Sample Adapter


The Small Sample Adapter, consisting of a cylindrical sample chamber and spindle, provides a defined system for accurate viscosity measurements of small sample volumes in the order of 2 to 16 mL. The Small Sample Adapter attaches easily to all standard Brookfield Viscometers/Rheometers.

REMOVABLE SAMPLE CHAMBER The design of the Small Sample Adapter allows the sample chamber to be easily changed and cleaned without disturbing the set-up of the viscometer or temperature bath. This means that successive measurements can be made under identical conditions.

TEMPERATURE CONTROL The sample chamber fits into a water jacket so that precise temperature control can be achieved when the Brookfield circulating temperature bath is used. The stirring action of the rotating spindle, plus the small sample volume helps to keep the temperature gradient across the sample to a minimum. Direct readout of sample temperature is provided using sample chambers with embedded RTD sensors connected to the DV-I+ and DV-II+Pro Viscometers and the DV-III Ultra. Working temperature range for the Small Sample Adapter is from –15°C to 100°C.

CYLINDRICAL GEOMETRY The Small Sample Adapter’s cylindrical geometry provides extremely accurate viscosity measurements and shear rate determinations.

DISPOSABLE SAMPLE CHAMBERS Disposable chambers for hard-to-clean materials. Kit comes complete with 100 chambers and special size water jacket, Part No. SSA-DCU. Available only for 13R Chamber. Additional chambers available in quantities of 100, Part No. SC4-13RD-100.

Helipath Stand

Designed for viscosity/consistency measurement of gels, pastes, creams, putty, gelatin and other non-flowing substances.

A Brookfield Viscometer or Rheometer is mounted on the Helipath drive motor and a T-bar spindle is attached to the viscometer using a special coupling. The drive motor slowly lowers or raises the viscometer so that the T-bar spindle creates a helical path through the test sample thus eliminating the problem of “channeling”.

Compatible with standard Brookfield Viscometers and DV-III Ultra Rheometers

Simple to set up and clean

Provides a solution for hard-to-measure materials

Complete with drive motor, 6 T-bar spindles with coupling, case, lab stand, rod and base

Features& Benefits

The Helipath Stand can be used with any standard Brookfield Viscometer model, and is

supplied complete with a set of six T-bar spindles and a special coupling.

Viscosity Standards

Silicone Viscosity Standards

Brookfield Viscosity Standards provide a convenient, reliable way to verify the calibration of your Brookfield Laboratory

These fluids are most commonly used to verify calibration of Brookfield Viscometers/Rheometers.

Viscometer/Rheometer. Brookfield Viscosity Standards are Newtonian, and they are available as either silicone or oil. Silicone fluids are less temperature sensitive.

For our customers needing a nonstandard viscosity or temperature range, our silicone fluids can be modified to meet most requirements. Viscosity Blends Calibrated at 25°C (77°F)

Minimum: 5 cP (mPa•s)

Maximum: 60,000 cP (mPa•s)

Blends will be within ±2% of requested value Temperature Calibrations

Minimum: 10°C (50°F)

Maximum: 80°C (176°F)

Minimum temperature increment: 2°C

Special Order Silicone Fluids

These fluids are recommended for use with the Brookfield Thermosel accessory.

Features& Benefits

Accuracy: ±1% of viscosity value

Excellent temperature stability

Recommended for use with Brookfield and most other rotational viscometers

Consumer products succeed in the marketplace in part because customers perceive which “textural characteristics” are desirable. This is certainly true with food products but also applies to cosmetics, pharmaceuticals, packaging, industrial materials and even adhesive type materials.

Why Measure Texture?

Texture analysis is primarily concerned with the evalua-tion of mechanical characteristics where a material is subjected to a controlled force from which a deforma-tion curve of its response is generated. These mechani-cal characteristics in food can be further sub-divided into primary and secondary sensory characteristics.

What is Texture Analysis?

With over 40 years experience in texture analysis, from the Boucher Jelly Tester to the Stevens rangeof Analyzers, Brookfield’s new Texture Division pro-vides customers with a complete texture assessment service. We specialize in the development of novel and innovative test applications and accessories for solid and semi-solid materials, enabling our custom-ers to maximize the practical value of their texture studies within all test environments.

Utilizing simple compression or tension forces, we are able to imitate almost all conditions imposed during the manufacture or handling of a wide range of foods, industrial materials and personal care prod-ucts. Such measures provide a “real life” insight into the physical properties of a product, often invaluable in maintaining consistent quality manufacture while minimizing rejects in production.

Calibration & Certification…for long life and optimal performance of your Viscometer, Rheometer and Texture Analyzer

For your viscometers and rheometers, we will inspect your instrument for wear, clean, adjust and lubricate the internal mechanisms, replace part of the sensing system

element (the pivot support assembly and, when required, the pointer shaft), and check your spindles. Spindles that are returned to a Brookfield Service Center are also straight-ened if necessary. In addition to this main-tenance, we calibrate and certify in writing that your instrument is operating within proper Brookfield specifications. This certifi-cation states that your instrument has been calibrated against standards which are trace-able to the National Institute of Standards & Technology (NIST). This is becoming an increasingly important requirement as industry throughout the world takes steps to comply with ISO 9000 regulations. If your instrument requires any additional repairs, we will contact you before proceeding.

For texture analyzers,we also inspect for wear, clean, adjust and lubricate internal mecha-nisms, and adjust,if necessary, the zero and span for properload cell performance. Certifiedcalibration weights can be purchased for your texture analyzer.

We will automatically remind you when it is time to return your instrument to Brookfield for your next Calibration and CertificationService.
