     Bio-Chem Fluidics provide with the Bio-Chem Valve range the OEM product engineers and end users with solenoid operated miniature valves and pumps to handle precision metering and dispensing applications.


The product range includes:
 
CHECK VALVES - Bio-Chek™ in-line check valves feature an inert flow path in high-purity, low-pressure applica-
tions. Unlike spring-actuated check valves that can restrict or impede the flow path, Bio-Chek™ valves feature a smooth flow path that minimizes shear and turbulence.

MICRO PUMPS - The inert, solenoid-operated, self-priming, fixed-displacement diaphragm pumps accurately dis-
pense high purity or aggressive liquids. Designed for continuous duty, they are guaranteed for up to 20 million ac-
tuations, corresponding to nearly 3,000 hours of continuous use at a 2 Hz cycle rate.

Bio-Chem Valve Applications:

Chromatography - The need for a fully inert fluid path in HPLC instruments is satisfied with the Bio-Chem Valve line of isolation and mixing valves. These miniature valves provide all-inert flow paths, small footprints, and the accuracy required by this demanding appli-
cation. Examples of valves used in HPLC instruments include a 2-way inert solenoid valve used as an off/on waste valve and as a pres-
sure relief valve to protect an analytical cell. Solenoid micro pumps are used to dispense liquid onto a piston in a high-pressure pump to maintain lubrication. Other products in use include wash pumps, reagent pumps, switching valves, and gradient valves.

Auto-Sampling - Today's high throughput applications require automated solutions. Pumps and valves from Bio-Chem Fluidics are used where liquids need to be moved quickly and accurately. Liquid handling and sample preparation units use isolation valves at the ends of sampling needles, syringes, and probe tips to conveniently and accurately dispense small volumes. Auto-sampling is an ideal use for three-way isolation valves and micropumps.

Blood Diagnostics - Reliability is crucial when patient results are needed. Bio-Chem valves have been specified in diagnostic instru-
ments worlwide to achieve fast test cycles, no sample cross-contamination, and precise results. A pinch valve can provide a periodic sample to the analyzer or be used to dispense a rinse to the sample probe. Reagent handling and dosing, line rinsing, and venting are all standard applications. From complete manifold assemblies to non-sticking pinch valves for liquid waste removal, Bio-Chem Valve is the ideal choice for your clinical chemistry application.

Medical Instrumentation - Miniature solenoid valves are used in a wide range of medical instrumentation including dialysis machines and automated slide staining equipment. Specific applications for valves include saline wash maintenance for surgery, pinching tubing used in disposable patient kits, and pumping solution away from the areas of patient contact. The adaptability of the Bio-Chem Valve standard product line allows our valves to be used in many 'non-standard', high-purity or chemically aggressive applications as well.

Biotechnology - The aggressive solvents and reagents used in most biotechnology applications require a chemically compatible fluid path. Bio-Chem Valve's pumps and valves provide this path with products made from the most advanced engineered polymers and elastomers. Applications involving small volumes, where precise dispensing, metering, and measuring are required, include solvent selection, liquid control on robotic systems, autopipetors, autosamplers, and liquid delivery to system analyzers.

Pharmaceutical - Bio-Chem valves and pumps serve many engineers who design custom machinery for applications such as filling machines, clean-in-place systems, and other specialized projects. Mixing valves can be used in dissolution testing equipment and com-
binatorial chemistry where multiple chemicals need to be selected.

Life Sciences - In the growing market for life science research Bio-Chem Valve products are used in some of the most demanding applications. These include DNA research, synthesis, sequencing, and manufacturing, as well as protein and peptide instrumentation. Two and three way valves are the products of choice due to their excellent sealing capabilities, fast response time, material composi-
tion, and most importantly, reliability and repeatability.

Environmental Analysis - The ability to measure and track our surroundings is critical in today's world. Bio-Chem valves are speci-
fied in instruments that measure air and water composition throughout the world. Air sampling equipment uses pinch valves to create a vacuum for drawing in air at specific intervals. Particle counters, daily environmental monitoring units, and marine biology instrumenta-
tion also utilize our solenoid valve technology to achieve accurate measurements.

Agriculture - There are various agricultural applications for Bio-Chem valves and pumps including distributing and controlling the flow of cleaning agents, reagents, vaccines, and hormones in a range of products. These include machines and instruments that innoculate and vaccinate animals against disease, monitor the health of animal populations, determine the composition and properties of soil sam-
ples, and automate simple processes previously done manually.
