Micro-Metering Valves

  • Flow Rates as Low as 3.5 µL/min (At 1.0mL/min incoming flow rate with room temperature water.)
  • 1/4-28 and 10-32 Designs Available
  • PEEK™ Polymer Construction, with PTFE

For fine control of fluid flow rates, our 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 Scientific® Micro-Metering Valves can also be used to regulate gas flow in helium sparging lines and as a flow-dependent variable back pressure regulator. For flow independent regulation of back pressure.

Flow path materials are PEEK polymer and PTFE (O-rings). All versions of this valve have 0.020" thru-holes.
