Valves
A variety of valves that can, depending on the product, be used to regulate pressure levels of liquid and gas in flow systems. These valves can be used for making connections between different lengths of tubing and connection points. Liquid and vacuum seals. A plethora of scenarios exist in which these valves can be used, each with a unique purpose and design for maximum safety and efficiency when in use, especially when pressure is of great concern.

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.
