Micro-Metering Valve, 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. Flow rates as low as 3.5 µL/min
