For fine control of fluid flow rates, Micro-Metering Valves can reduce outgoing flow to as low as 3.5 μL/min (derived with water at room temperature at 1.0 mL/min incoming flow rate). These needle valves are perfect for use with peristaltic pump fluid-transfer applications, mass spectrometry, and fraction collection.
Upchurch Scientific® Micro-Metering Valves are used to regulate wash station flow on CTC/LEAP liquid handlers. Flow path materials are PEEK™ polymer and PTFE. All versions of this valve have 0.020” (0.50 mm) thru-holes.
