The PrimeLine In-Line check valve incorporates many of the innovations of our HPLC self-priming replacement check valves. It is a rapid-closure cartridge valve that features very low resistance to flow, low internal volume, and operates independently of gravity. It features crush-proof construction. The valve may be used whenever flow needs to be restricted to one direction. Applications include prevention of post column derivatization fluids from back-flowing into the column in the event of mobile phase pump failure.

1/8" ball cartridge is protected from solvent contamination by a .250" diameter x .062" thickness 10 micron frit. If you see a large pressure drop across the valve with 1/8" ball cartridge version when you run at a very high flow rates, for example at 100 mL/min., please contact us for the solution.

This in-line CV is available for Acetonitrile-resistant version. High Temperature version that will operate at up to 200°C at 5,000 PSI is available. Link to High Temperature Version 

All 1/16", 1/8" & 3/16" ball In-line CV are suitable for SFC application.
