The Bio-Chem Valve™ Solenoid Operated Micro-Pump is a solenoid operated device designed to provide a precise, repeatable and discrete dispensed volume of fluid. The pumps use a flexible diaphragm to isolate the solenoid actuation mechanism from the fluid path (read more on micro-pump valve operation).

Bio-Chem Valve™ Solenoid Operated Micro-Pumps are particularly suitable for use in highly aggressive and / or high purity fluid applications such as analytical chemistry and clinical diagnostics. (Download brochure – Solenoid Operated Micro-Pumps).

Features of the Solenoid Operated Micro-Pump:

12 volt or 24 volt DC solenoidChoice of pump style Threaded ports: Available dispense volumes; 20µl, 30µl, 40µl, 50µl, 60µl, 100µl, 125µl, 150µl, 175µl, 200µl, 225µl, 250µl Manifold mount: Available dispense volumes; 20µl, 30µl, 40µl, 50µl, 60µl

Inert fluid path with only three wetted components (body, diaphragm and check valve) made entirely from chemically inert materialsChoice of materials -(read more - Plastics & Polymers Reference Page)Body materials: PTFE, PEEK, PPS & POMDiaphragm materials: PTFE, EPDMCheck valve materials: EPDM, FKM, FFKM

Self-priming – At start-up, pumps are able to draw air. The suction created by the pumps is sufficient to pull liquids from an unpressurized container located up to 1.3m beneath the pump.

The Bio-Chem Valve™ Solenoid Operated Isolation Valve offers instrument designers a completely inert, non-metallic fluid path. The valves use a flexible diaphragm to isolate the solenoid actuation mechanism from the fluid path (read more on isolation valve operation). Isolation Valves offer low internal volumes, precise flow control and excellent ease of installation.

Bio-Chem Valve™ Solenoid Operated Isolation Valves are particularly suitable for use in highly aggressive and / or high purity fluid applications such as analytical chemistry and clinical diagnostics. The highly inert fluid path is especially useful in liquid chromatography, genomics and protein synthesis applications. The high flow factor makes these valves well suited to environmental and water analysis applications. (Download brochure – Isolation Valves).

The Bio-Chem Valve™ Solenoid Operated Pinch Valve allows flow passage through a flexible tube which is "pinched" off to produce a tight seal. Only the easily replaceable tubing comes into contact with the fluid making this style of valve ideal for applications requiring frequent changes of the flow path (read more on pinch valve operation).

Pinch Valves have specific features that lend themselves to particular applications: Unobstructed flow path. Pinch valves create minimal pressure drop, which is important for controlling downstream instrumentation.Tubing is soft yet durable. Pinch valves are highly tolerant of particulates in the fluid stream.Tubing is easy to change. The user can change tubes if a sterile fluid path is required (for instance, blood collection) or when chemicals create clogs (for instance, system waste lines).Zero dead volume. Consecutive samples are not contaminated by the previous one.Fluid contacts tubing only. The materials of construction of the body and plunger do not have to be highly corrosion resistant, which means pinch valves are often very economical when compared to alternatives.

The Bio-Chem Fluidics Electric Rotary Valve is a stepper motor operated fluid handling valve. The Electric Rotary Valve provides an inert flow path for aggressive fluids. The inert path is achieved by aligning holes in a PCTFE rotor with holes in the PTFE body. (Download brochure – Electric Rotary Valves). (Download User Manual).

Features of the Electric Rotary Valve:

Inert fluid path - the fluid in the Electric Rotary Valve contacts only two components; the PTFE valve body and the PCTFE rotor. This ensures a completely non-metallic, corrosion-resistant path.Multiple flow configurations - the Electric Rotary Valve is available in five different flow configurations (see below).Unobstructed flow path - precise machining creates an unobstructed flow path through the Electric Rotary Valve minimizing dead volumes and providing a lower pressure drop than solenoid mixing valvesOEM focused – the Electric Rotary Valve is available with and without the NEMA 17 stepper motor and controller board.
