Micro valves are available as both screw top and crimp top vials. When used with a glass vial, only PTFE and glass are in contact with the contents. Operation is extremely simple, using the green and red buttons in tandem with a needle inserted through the septum to retrieve the sample. Micro push-bottom valves are highly dependable, leak-tight closures for vials and other laboratory containers. They provide an inert, high-pressure seal, and can be used repeatedly for unlimited syringe-needle access to sample.

Micro-metering valves, Upchurch Scientific®

Supplier: UPCHURCH SCIENTIFIC

For fine control of fluid flow rates, these valves can reduce outgoing flow. These needle valves are perfect for use with peristaltic pump fluid transfer applications, mass spectrometry and fraction collection. They can also be used to regulate gas flow in helium sparging lines and as a flow-dependent variable back pressure regulator.
