Solenoid valve system
These 10- and 16-mm analytical valve systems are designed for the analytical, medical, and biotechnical industries. The 6600 Series of 2- and 3-way valves should be more easily installed on a manifold because all inlets are together on one side. They have Simriz isolating diaphragms that completely separate the actuator from the fluid. A stainless-steel plate isolates the actuator from the coil, ensuring no heating of the media. Applications include blood analysis, chromatography, peptide synthesis, and kidney dialysis.

Minimatic Electronic Valves and manifolds are designed to provide a complete system for efficient interface with electric and electronic circuits and are recommended for a range of applications in the biomedical field. The standard valves covert low-voltage, low- current signals into high-pressure (100 psig) pneumatic outputs. Optional low-pressure/ medium-flow and low-pressure/high-flow valves are available. The 2- or 3-way control valves contain no sliding parts.

Air vacuum pump
This line of dc-powered miniature pumps reportedly includes the industry's smallest. They are recommended for space-critical air and gas applications, and battery-powered portable equipment. Motors feature ironless winding technology to reduce current draw and increase life. Some applications include blood pressure monitors, gas chromatography, and medical diagnostic equipment.

Combining the speed of a canned motor vacuum blower with the productivity of a high-capacity mechanical pump, 1739 Series direct-drive pumps have no external shaft seal, maximizing uptime of the vacuum system. Capacity can be up to 2,600 cfm. An optional bypass feature can decrease pump-down time by 5 to 50%.
