Advantages of J-KEM RoboticsCustom Design

While others start from an existing design, then try to make your application fi t their instrument, every J-KEM workstation is designed from scratch to implement your automation task effi ciently and with an eye towards future expandability. J-KEM’s experience in lab automation, including temperature control, reactor design, fl uid delivery, solid and solution phase synthesis is invaluable when optimizing the design of custom robotics.

You Own the SolutionJ-KEM believes that you should not only own the instrument, but you should own the technology that created the instrument. That’s why we are the only company that releases the original source code with every robot. This gives you the power to change every aspect of the robot’s operation as your automation needs change.

Personal ServiceJ-KEM is committed to personal service, offering any support that’s needed to assure the successful integration and productivity of our automation solutions. With one phone call, you can talk to the engineer who designed your robot, the engineer who installed it, and the software engineer who wrote the program.

ValueJ-KEM’s custom robotics are often half the price of other companies’ “one-size-fi ts-all” alternative. While many of the modules on a workstation are standard J-KEM products, we also use the best available instruments like balances, bar code readers, and pumps to assemble the fi nal workstation in the most affordable and effi cient manner.

Polymer Compounding Robot Modules: 4-Temperaure zone reaction block, balance, bar code reader, heated & cooled reagent block, cooled 4-position sonicator, precision syringe pump with 16 reagent ports, 6-zone temperature controller, and needle wash station.

Custom SoftwareCustom software is written for every workstation to provide an intuitive user interface. The procedure’s setup, the way data is read into and out of the program, and the exact sequence of program steps are all customized to make the operation of your robot both effi cient and user friendly.

Why is it important to own the original source code?Without the source code, you’re stuck with the robot you have rather than the robot you need as your automation needs change. For example, suppose the robot’s original task was weighing and dissolving samples to specifi c concentrations, but now you need it to add reagents to 4 mL septum vials in a temperature controlled reactor with mixing. In most cases you’d need to purchase a new robot. Even for small changes, if you don’t own the original source code, then you’re 100% dependent on the company who does. J-KEM offers ongoing software support for all of our customers. But still, to own the tools that place you in control of your own workstation is invaluable.

It’s not really enough to own the code if it’s not easy to use.

Fraction CollectorsJ-KEM manufactures custom fraction collectors for any research application, from a simple 2 axis to a sophisticated 3 axis instrument running a custom, user specifi ed, program.

Features: · External inputs & outputs for tube advance · Collect to a single or multiple racks · Fractions taken as a function of: - Time - Input voltage - User specifi ed parameter · Custom inputs/outputs to interface with other instruments

Custom fraction collector holds 12 microtiter plates

This is great stuff, but what I really need is. . . . . . .

The Endeavour’s affordable price makes it a perfect “intelligent fraction collector.” The Endeavourcan be programmed to collect fractions based on any input parameter and according to any pattern. For example: 1) Place the fi rst 40% and the last 40% of any peak in one common test tube, but put the middle 20% in a GC vial for analysis.

2) Collect each peak to a single tube. After the fractionation process is done, go back and transfer 1mL of each collected peak to a GC vial for analysis.

Programmable Syringe Pumps

• Flow rates from 0.75 µL/min to 375 mL/min

• Syringe automatically refi lls to deliver any volume from any syringe

• PC control and data logging with KEM-Commander software

The SYR-1200 syringe pump automates the addition of reagents at user entered rates. A programmable distribution valve allows the system to dispense to and withdraw from up to 8 reagent bottles or reactors in any sequence. In addition to the standard programs pre-loaded in the controller (see below), J-KEM offers custom programming at no additional charge to automate virtually any fl uid delivery task. Additionally, KEM-Commander PC software allows the user to build sophisticated delivery programs with an intuitive drag-n-drop interface.

KEM-Commander Software

KEM-Commander is standard with every pump and allows the user to construct sophisticated syringe pump programs in an intuitive drag-n-drop environment. Programs can then be run/saved/recalled from the PC or uploaded to the pump.

Standard Syringe Pump ProgramsStandard programs are permanent and pre-loaded in the syringe pump controller

Program 1. Timed Addition Sequentially adds up to 16 reagents to a single or multiple reactors at user specifi ed rates. The syringe automatically primes and refi lls with the active reagent as needed.

Example (pump fi tted with a 5 mL syringe): 1) Add 12mL of reagent A at a rate of 3 mL/min 2) Add 2.5mL of reagent B at a rate of 0.025 mL/min 3) Delay 1 hour 4) Add 10mL of reagent C at a rate of 60 mL/min

Program 2. Program Loader Use KEM-Commander PC software (included) to construct a custom syringe pump program in a drag-n-drop visual environment. Program Loader then uploads that program to nonvolatile memory in the syringe pump controller. Once stored in the controller, the program can be run at any time with no PC needed. Construct programs for parallel reactions, fi lling titer plates, washing, or any custom application.

Program 3. PC Control Places all functions of the syringe pump under PC control. Useful for robotic applications or when part of a larger automated reaction system.

Program 4. Custom At no additional charge, the user can specify a custom syringe pump program. This program is written by J-KEM and stored as one of the permanent programs.

Program 5. Update Manager Allows new or updated programs, available from J-KEM (via E-mail or web site), to be uploaded into permanent memory.

Program 6. Concurrent Addition (SYR-2200 only) Adds two reagents in parallel to a common reaction at two independent rates.

Program 7. Serial Dilution (SYR-2200 only) Repeatedly dispenses two reagents in a user specifi ed ratio.

Program controlled distribution valve fi lls and dispenses from up to 8 ports

The SYR-1400 system includes both the syringe pump and KEM-Pump software. KEM-Pump is open source, graphical software that includes both pre-written applications and the original source code, in VB.Net, to allow users to create their own custom applications. KEM-Pump is a bold advance in laboratory automation that provides the user unprecedented control over how the syringe pump operates. KEM-Pump handles the low level tasks, like serial communications, then exposes high level functions for virtually any syringe pump action, greatly simplifying the effort needed to write new applications. For example,the code block below fully implements dispensing any volume of reagent at a user specifi ed rate; syringe refi lls are handled automatically. The list of functions and a complete programmer’s manual is available at jkem.com.

Timed Addition - Adds a single reagent (any volume) to a single reactor at a user specifi ed rate Multi-Step Timed Addition - Adds up to 16 different reagents, independent volumes and rates to a single reactor Multi-Reactor Addition - Adds a single reagent to 1-7 different reactors at independent rates and volumes Program Builder - A drag-n-drop application, for non-programmers, to build sophisticated pump programs

Pre-written applications include:

The SYR-1400 is the most versatile syringe pump available. The SYR-1400 is operated from a PC running J-KEM’s KEM-Pump software. KEM-Pump implements all the programs of the SYR-1200 plus additional programs for serial and multi-reactor reagent additions. Unlike any other syringe pump, KEM-Pump is an open source code application that allows researchers with programming experience to create their own applications without limitations (see blue insert below).

NEW Model SYR-1400 Syringe Pump


Comparing the Features of the SYR-1200 and theSYR-1400 Syringe Pump Systems

J-KEM’s two syringe pump systems, the SYR-1200 (page 10) and the SYR-1400 (page 11) share many of the same features, but differ in several important ways that may make one system better suited for your application. The key differences between the SYR-1200 and the SYR-1400 are 1) the SYR-1200 has its own syringe pump controller allowing it to be used as a stand-alone instrument while the SYR-1400 requires a PC for operation, and 2) the SYR-1400 is substantially more versatile, taking advantage of the power of a PC.

The SYR-1200 The SYR-1400

Controller The SYR-1200 is operated from its own computer controller which means that a PC is not required for operation. The controller stores and recalls the various programs and has a keypad for user input and a screen to display the experiment’s progress.

Both the SYR-1200 and the SYR-1400 use the same pump module. This means that both systems provide identical performance in regards to fl ow rate range

and accuracy. It also means that both system use the same syringes, distribution valves and

other accessories.

Syringe• Sizes: 10 µL to 50 mL• Glass & Tefl on wetted parts• Dispense resolution is 1/48,000 of the syringe size in use• Easily interchangeable

Valve• With 3 to 8 program selectable ports• All wetted Tefl on parts

Optional I/O• Use external inputs to start/stop fl ow, change fl ow rate, or port position.• Control external valves or other devices under program control.

Motor• Stall detector

Controller The SYR-1400 is operated from your PC. Programs are stored and recalled, and the experiment’s progress is displayed on the PC.

Standard ProgramsThe syringe pump controller has the most common and useful pump applications loaded into permanent memory (see page 10).

Custom ProgramsJ-KEM offers to write one custom program and load it into permanent memory at no additional charge.

Creating New ProgramsThe SYR-1200 comes with a free PC application called KEM-Commander. With KEM-Commander, sophisticated script-style programs can be built in a drag-n-drop environment that can then be run from the PC.KEM-Commander programs can be thousands of commands long. Examples of program script commands are shown below.

Standard ProgramsThe SYR-1400 comes with KEM-Pump graphical control software that runs the syringe pump module. KEM-Pump implements all of the standard programs of the SYR-1200 plus several others.

Custom ProgramsJ-KEM offers to write one custom program and add it to your copy of KEM-Pump at no additional charge.

Creating New ProgramsWith the SYR-1400, new programs are created by adding your code to J-KEM’s open source syringe pump application, KEM-Pump, written in Microsoft’s VB.Net. For researchers with programming experience, the versatility of the syringe pump system is limited only by your imagination. KEM-Pump contains high level functions that provide intuitive access to every syringe pump feature. Using these functions, virtually any syringe pump program can be created in a matter of hours. For researchers without programming experience, one of the screens in KEM-Pump builds new syringe pump programs by dragging commands to a script-style command list. KEM-Pump also has an intuitive graphical interface that displays the status of a running experiment in real-time.

Continuous Flow Reactor

Something unusualfrom a scientifi c

instrument company

From the beginning, J-KEM has worked to be part of the research community, rather than just a supplier to the research community. That’s why J-KEM offers substantial Academic discounts on every item we sell, because we believe that supporting the next generation of researcher is part of our corporate responsibility. J-KEM’s Continuous Flow Reactor continues that commitment by supplying the high quality instruments that are needed for research today. At the time this catalog was printed, our continuous fl ow reactor was still in development, but even in development, its performance and features so signifi cantly exceeded those of any other fl ow reactor that we decided to provide a preview of what’s coming.

J-KEM’s continuous fl ow reactor can be confi gured to operate in either of two modes, reaction discovery mode or preparative synthesis mode. In discovery mode, a homogeneous mixture of reaction materials are loaded into a sample injection loop which are then injected into the fl ow reactor. The reactants fl ow through the reactor being pushed forward by a continuous stream of clean solvent. While the reactants from the fi rst injection are in the reactor, the reactants for a second injection are being measured out and mixed by a robotic workstation that both prepares reactants for injection and acts as a fraction collector for the reaction products as they elute. Up to 128 reactions can be fully automated without requiring operator intervention. In discovery mode, 50 - 100 mg of products are typically produced in each experiment.

J-KEM’s continuous fl ow reactor can also be confi gured to run in preparative mode to produce gram quantities of reactants. In prep mode, the reactants are continuously pumped into the reactor in the desired ratios by adjusting the fl ow rate of the two reactant pumps. This method was used to run the reaction shown at the left, which resulted in the preparation of 1.94 g of the aryl amine during a 3.5 hour run.

Reactor Features• Multiple reactor options: - Stainless steel, Inconel, PEEK, PTFE - Tube OD’s of 1/16” and 1/8” - Tube ID’s from 0.02” to 0.14” - Reactor volumes from 1 mL to 20 mL• Flow rates from 0.01 to 5.0 mL/min• High pressure (4000 psi) pump• Temperature range from RT to 300o C• Back pressure regulators from 100 to 1000 psi• Manual or fully automated operation

Fully Automated SPS ReactorSolvent is held in the reactor by computer controlled nitrogen back pressure.Single key stroke commands provide the functionality to:

· Set up a new reaction · Mix the reactants and resin · Filter & wash the resin · Cleave and collect fi nal products

The SPS reactor works by pressurizing the reactor base with nitrogen gas until it exactly offsets the pull of gravity. In this way, solvent can be added to a single reactor with none of it dropping through the frit. As reactors are sequentially fi lled, the SPS computer regulator precisely controls the fl ow of nitrogen to maintain the reactor’s back pressure to +-0.001 psi. Using nitrogen back pressure to hold solvent in the reaction tube eliminates the need for mechanical valves or other mechanical devices which prevents automation of the SPS process. Reactions are mixed by placing the reactor on a bench top shaker, or by increasing the pressure in the base to cause continuous or intermittent bubbling up through the frit mixing the resin and reactants. Reaction setup, mixing, washing, and fi ltration are accomplished by a single key stroke on the computer pressure regulator. Can be combined with J-KEM’s Eclipse robot for fully automated, multi-step SPS reactions.

The KEM-Vap Solvent Evaporator uses heatednitrogen gas and variable vacuum pressures to rapidlyevaporate volatile and nonvolatile solvents in the same evaporator. The evaporator cover directs a jet of nitrogen gas into each cell of a titer plate or vial in a vial rack for uniform and consistent evaporations. For nonvolatile solvents, a combination of vacuum and heated nitrogen removes solvents in a fraction of the time needed when vacuum or heated gas is used alone. Made from stainless steel and ultra high density polypropylene the evaporator is not harmed by organic or aqueous solvents. Custom evaporators made on request.

Two Styles of Regulator to Choose FromDVR-200The DVR-200 is designed for continuous vacuum sources, such as oil-fi lled vacuum pumps, aspirators, or systems that are “always on”, like in-house vacuum systems. The DVR-200 regulates pressure by opening and closing a valve that separates the vacuum source from the system being evacuated. In most cases, the DVR-200 is the best choice.

DVR-280The DVR-280 is designed for use with diaphragm vacuum pumps. In some systems, pressure is regulated by turning on and off the vacuum pump itself. The DVR-280 extends the life of diaphragm pumps by not exposing the diaphragm to full vacuum pressures when starting, which increases pump life by 100%.

A Note About QualityJ-KEM uses the highest quality components available. For example, most vacuum controllers use a silicone fi lled vacuum transducer (because they cost less), but J-KEM uses a stainless steel diaphragm transducer. Also, rather than a standard vacuum valve with Viton seals, J-KEM uses a custom stainless steel valve with Tefl on seals. These, and other enhancements provide the chemical resistance needed in chemistry laboratories.

New in 2009At the heart of J-KEM’s 200-Series controllers is a new, high speed microprocessor that performs 3 functions:

1. Power Regulation J-KEM’s original power control computer is replaced by a next generation microprocessor. The power control computer is J-KEM’s patented technology that adjusts power to the heater 2048 times per second resulting in 0.1o C regulation.

3. Upgradable Programming Software modules can be uploaded to the processor, at no charge, adding new capabilities to the controller. For example, automatic detection of exothermic reactions. You may not see the exotherm in this plot (and it was a big one), but the microprocessor does. You can’t see it because as it occurred, the temperature controller stopped powering the heater to compensate for the heat being generated by the reaction.

2. USB Communications PC communications and free KEM-Net software enables remote PC control, GLP/GMP compliant data

collection, and multi-temperature ramps built in an Excel-like table.

Serial Communications, PC Control, Data Logging &The J-KEM Advantage

The J-KEM Advantage

PC Control, serial communications, networking, and data logging explained.....J-KEM supports three serial communications standards: USB, RS-232, and RS-485. Each has advantages and limitations.

Controllers connect to the PC’s USB ports or a USB hub.

RS-485 has the unique advantage that cable lengths between the instrument and PC can be as long as 4000 feet. For lab arrangements that require long cable runs, RS-485 is a valuable alternative. Contact J-KEM for ordering assistance. J-KEM’sKEM-Comm software is required for RS-485 communications.

Research grade temperature (200-Series) and vacuum regulators contain two next-generation FLASH programmable microprocessors.

The patented power control computer is the heart of every J-KEM temperature controller. The computer adjusts power to the heater 2048 times per second resulting in 0.1o C regulation of any reaction and virtually eliminates overshoot of the entered setpoint on initial warming.

The communications processor, new in 2009, implements PC

control, data logging, and our new web based FLASH Modules. FLASH Modules are programs that can be downloaded from J-KEM’s web site to your controller at no charge. An example of a FLASH module is the Exo/Endo module that automatically quantifi es, then alerts the user when an exothermic reaction is detected.

RS-232 A hardware RS-232 port is available, but usually not needed. J-KEM’s USB port includes a virtual RS-232 port driver that operates with software utilizing RS-232 communications.

J-KEM USB This is the standard port on 200-Series temperature controllers and the Digital Vacuum Regulator. The advantage of USB is that it’s present on all PCs and supports connecting multiple controllers to a single PC. The only limitation of USB is that cable lengths cannot be longer than 15 feet without using a USB extender (offered below).

Heating mantles are the safest method of laboratory heating because they avoid the burn hazards associated with other styles of heaters. Heating mantles uniformly heat glassware and remain cool to the touch, even at internal temperatures > 300o C.

Instatherm® Oil BathsThe intelligent design of the Instatherm oil bath, from Ace Glass, includes features that make it the safest and most reliable oil bath for laboratory use. The metal alloy heating element is fused directly to the surface of the glass bath and then covered with a tough silicone rubber layer and a glass insulation layer which serves as both a thermal barrier and protects against physical shock. The bottom of the

Instatherm is not heated so the bath can be placed on magnetic stirrers. The Instatherm bath can be operated up to 250o C. Includes power cord.

For maximum versatility, J-KEM recommends the INS-150 and INS-190 oil baths. These baths can be used with any 200-Series temperature controller, which can also be used with any heating mantle (above). Thus, the same controller can be used with either heating mantles or oil baths.


Series-OS heating mantles can be placed directly on top of magnetic stirrersproviding vigorous mixing using a stirring bar.

Series-TM heating mantles have a self-supporting aluminum shell. The TM mantle is stable on bench tops, and with extra insulation, the exterior remains cool to touch.Maximum internal temperature of 450o C.Not suitable for magnetic stirrers.

The fi rst temperature controller made by J-KEM, sold to Dr. Kurt Moedritzer of Monsanto

(Dr. Moedritzer also purchased controller #2. Our fi rst loyal

customer!!)

J-KEM Scientifi c’s employees gathered around the fi re pole of our fi rst facility, the fi re house.

1988Incorporated as J-KEM Electronics. Offering one product, the Model 260 temperature controller, we fi nish our fi rst year with sales of $784.00.

1989Flush with cash from its fi rst year sales, J-KEM doubles its product line and begins offering the Model 210.Attended the Fall ACS meeting, exhibiting all four of the controllers we owned, then spent sleepless nights worrying how we’d fi ll orders if they came in.

1990J-KEM’s fi rst major customer was Dr. James Zeller of Parke Davis. J-KEM expands its manufacturing area 400% by moving from just the corner to occupy the entire basement (sorry girls about your play house).

1993Moved to our fi rst commercial building.Hired our fi rst full time employee (Li, above).Built the fi rst power control computer (8 bits, 4 MHz!!).

1994 - Incorporated as J-KEM Scientifi c

1995 - Purchased our fi rst building, a 1930’s fi re house.

1998 - First years sales >$1,000,000.

1999 - First robot sold to Dr. Glass of Zenica.

2000+ - Emphasis in lab automation, parallel reactors, and robotics.

2008 - Staying abreast with advances in technology:

• Third generation power control computer• Second generation Syringe Pumps• Two new robotic designs• Custom lab automation instruments and software

The Road We’re On

(together)

J-KEM appreciates the relationship we’ve had with all of our customers. It’s more than just the obvious fact that without you, J-KEM

would not be in business. We appreciate the friendships and the ideas we’ve received from world class scientists, that without, many of our best products wouldn’t exist. Don Korte gave us the idea for

the miniature overhead stirrer, Martyn Fordham, the Personal Reaction Station, Dr. Bruce Hamper the Solid Phase Synthesis Regulator, and the unknown chemist from Abbott who came to our booth at the ACS show to say “I don’t need a temperature controller, I need a vacuum regulator

that works”. This resulted in our Digital Vacuum Regulator.

Pictured are the original (left) and new (right) Model

210-Timer circuit boards

40 MHz microprocessor enables * Exo & Endotherm analysis * USB communications * Enhanced safety

In 2008, J-KEM completed the redesign and implementation of the 3rd generation of its power control computer. The new design uses a FLASH programmable microprocessor that can be updated with new controller features from J-KEM’s web site.
