Quick-Stop Luer Check Valve

• Check valve protection with luer convenience
• Automatically open when engaged

The Upchurch Scientific® Quick-Stop Luer Check Valve offers check-valve protection with luer connect/disconnect convenience. Just insert the valve into your low-pressure system with standard 1/4-28 flat-bottom fittings and the included luer components. The check valve is automatically opened once the luer connection is engaged, allowing flow in either direction. Disconnecting the luer union causes the check valve to close.

APPLICATION NOTES:

Inlet Solvent Reservoir: Quickly change your solvent on the low pressure end of an HPLC system, while preventing potentially hazardous spills. Just install a Quick-Stop Luer Check Valve Assembly between your solvent reservoir and the pump, with the valve towards the bottle. The valve will prevent solvent leakage from the line coming from the reservoir, while the check valves in your pump prevent spills from the line leading to the pump. With both lines still full of solvent, this system also eliminates the need to reprime your pump.

FIA Sample Injection: The Quick-Stop Luer Check Valve provides a practical means to introduce sample into FIA and other low pressure systems, when used in conjunction with our P-612 Pressure Relief Valve Tee. Simply connect the Tee into the appropriate flow path line with the included fittings and thread the P-697 Quick-Stop Luer Check Valve onto the 1/4-28 male end of the Tee. Sample can then be introduced conveniently by utilizing a standard luer-tipped syringe. The check valve is automatically opened when the syringe is attached, and closed when the syringe is removed.
