Valves eliminate need for tubing sets to connect individual valves
Boonton, NJ (July 27, 2012) – Bio-Chem Valve™ Flow Selection Valves reduce the number of connections and potential leak points in flow mixing and selection for highly aggressive and high purity fluid applications. Flow Selection Valves combine multiple valve actuators into a single compact unit around a central block, allowing mixing or selection of any combination of between two and eight individual source streams.
Bio-Chem Fluidics’ Flow Selection Valves for highly aggressive and high purity applications.
Flow Selection Valves use a flexible diaphragm that isolates the solenoid actuator from the fluid path. All wetted parts are constructed from highly inert, non-metallic materials such as PTFE or PEEK. Flow Selection Valves are available in a range of orifice sizes from 0.032” to 0.125”, and power ratings from two to eight watts.
Valves feature a radial manifold block, eliminating the differences in flow path length and timing found in linear manifolds. Each solenoid actuator is individually adjusted by the manufacturer to ensure equal flow rates at the same pressure.

Manufacturing and sales of finished products and electrical sub-assemblies has already begun, with more new products being rolled out over the coming months. The Shanghai factory will also serve as a global sourcing centre for operations in North America and Europe. The company has begun identifying local suppliers of key components. Bio-Chem Fluidics is one of four Halma companies (including Castell Safety, Labsphere and Ocean Optics) that have begun production at the site.
According to Tim O’Sullivan, the company’s Vice President of Manufacturing, “We see China and the rest of Asia as a major growth market and we want to emphasise that we’re manufacturing in Asia primarily for an Asian customer base.”

Cambridge, UK (April 29, 2009) – Bio-Chem Fluidics, under its Omnifit® brand, has launched a new bubble trap for effective, in-line removal of bubbles in aqueous solutions. Positioned upstream of sensitive instrumentation and pressure rated up to 30 psi, the bubble trap protects valuable sensors from damage and prevents errors caused by gas bubbles in an analytical flow system. Typical applications include flow analysis systems, liquid chromatography, enzyme reactors and flow-through biosensors.
The principle of operation is simple: when a fluid containing bubbles flows through the device, any bubbles are forced through a micro-porous, hydrophobic membrane, while the fluid is retained within the bubble trap. Because the membrane function depends on its hydrophobicity, the bubble trap is only suitable for use with aqueous systems.
The unit is quick and easy to connected in-line using 1/4”-28 UNF female threaded ports and fittings such as Omni-Lok™. While the maximum flow rate is dependent upon the amount of bubbles in the liquid, the typical operating range is 0.5 – 2.0ml/min. Up to 6ml/min can be achieved if few bubbles are present in the liquid.
Cambridge, UK (February 5, 2009) - Bio-Chem Fluidics is helping instrument manufacturers save time and assembly costs by offering pre-assembled tubing sets to their exact specifications. Kits for complete instruments can be supplied under a single part number, enabling manufacturers to simplify their purchasing and inventory management.
Customers can mix and match a wide range of ferrule types, fitting nut designs and colours, tubing sizes and materials to custom configure their ideal system. They can also choose single or multiple tubing sets, fittings at one or both ends of a line, different coloured fitting nuts for colour coding fluid lines, and mesh wrapping to simplify tubing management within an instrument.
The tubing sets are assembled to exact specifications by Bio-Chem Fluidics’ skilled production staff, ensuing a perfect, leak-free connection. The most popular options for instrument manufacturers are from the Omni-Lok fitting range, which features a compact fitting nut in robust, glass-filled polypropylene or PEEK and a choice of chemically inert ferrule types.
The Omni-Lok fitting nut also features a recess to house the ferrule, allowing maximum thread engagement with the port. This ensures the system stays sealed up to the rated pressure even in shallow or PTFE ports. The nut can spin freely, eliminating tubing twist and is available in a choice of nine colours for easy colour-coding of fluid lines. Fitting nuts are available in robust, glass-filled polypropylene or PEEK and in 1/4”-28 UNF, M6 and 5/16″-24 UNF thread types.
To support the new range of tubing sets the company has also published a comprehensive new fittings systems catalogue which details the complete range of Omnifit® fittings, connectors and adaptors, with particular emphasis given to the Omni-Lok range.
Cambridge, UK (October 20, 2008) – Bio-Chem Fluidics is showcasing its extensive range of precision fluid handling products for high purity applications at this year’s Medica exhibition in Düsseldorf, Germany (Booth 01/E06).
Particular prominence will be given to the Bio-Chem Valve brand of pinch valves developed specifically for medical applications. Featuring accurate stroke adjustment, small footprint and low wattage, the valves also come with optional extras including a quiet operation function and feedback sensor, making them ideal for medical device manufacturers.
New additions to the extensive Omnifit range of inert fittings will also be on show, including a new range of torque control tools for easy, hand-tight installation. In addition, Click-N-Seal fittings from Diba Industries will be on display. A new, comprehensive fitting systems brochure will also be available at the booth to take away.
Bio-Chem Fluidics has many years of experience in providing instrument manufacturers and laboratories with inert, miniature fluid handling components. Application specialists will be on hand at the show to answer questions about the entire product range and demonstrate products.
Cambridge, UK (September 25, 2008) – Bio-Chem Fluidics manufactures a range of Omnifit® bottle caps and accessories which prevent harmful chemicals and solvent vapours from escaping, ensuring a safe and dependable solvent delivery system in the laboratory.
Following an extensive re-engineering programme, the company has now reduced the cost of its T-Series bottle caps. Featuring a PTFE* inner portion, which offers a high level of chemical compatibility, T-Series caps have an anti-twist design which allows the inner body of the cap to spin freely. This prevents tubes being twisted when the cap is fitted or removed and eliminates the need to disconnect fluid lines before unscrewing the cap.
The caps are very easy to use and require no fittings – standard 1/8” laboratory tubing is simply pushed through Luer ports on the top of the cap. These ports allow connection of other tubing sizes and types with a range of Luer adaptors which are available separately. Optional integrated check-valves and filters are also available, enabling pressure to be equalized within the bottle as liquid is drawn out and preventing particulate contamination.
