Miniature isolation valves for hazardous fluids
Bio-Chem Valve has developed inert, perfluoroelastomer miniature isolation valves for the handling of aggressive, particulate-laden and high purity fluids in scientific and medical equipment.
Pinch valves take on aggressive liquids
A new range of inert, wide aperture, nonsticking pinch valves provides precise control of liquid and gas flow in medical and analytical equipment.
Applications include portable liquid handling equipment, repetitive sampling equipment and instruments requiring multiple flow path control within a small area.
The new, compact design reduces the footprint typically required by standard isolation valves, helping designers of analytical and medical instrumentation meet the challenge of smaller sample sizes and the need for portable, automated liquid handling equipment.
Up to four manifold mounted valves can fit in a 32mm2 space, and the lighter 12 to 18g weight facilitates use on robotic arms in sample handlers.
Two versions incorporate a rectangular body with 0.25-28 flat bottom ports on the bottom or on the side.
The manifold version has a screw-in collar for easy assembly and exchange.
The manifold version can be combined with an existing manifold, or Bio-Chem Valve can custom design an efficient pre-assembled, space-saving module to meet specific flow schematics and eliminate complex tubing and fittings.
The two-way normally closed valve features dual pin electrical connections, low power consumption, low internal volume, and a high cycle life.
The valve is constructed of Peek or PPS with Teflon wetted materials.
Alternative materials and customised modifications are also available.
