Micro-Metering Valves
For fine control of fluid flow rates, Micro-Metering Valves can reduce outgoing flow to as low as 3.5 μL/min*. These needle valves are perfect for use with peristaltic pump fluid-transfer applications, mass spectrometry, and fraction collection. Upchurch ScientificR Micro-Metering Valves can also be used to regulate gas flow in helium sparging lines and as a flow-dependent variable back pressure regulator. Flow path materials are PEEK polymer and PTFE. All versions of this valve have 0.020” (0.50 mm) thru-holes.
*At 1.0 mL/min incoming flow rate with room temperature water
