Check valves for OEM manufacturers

The performance of an HPLC pump is only as good as the check valves in it. Flow stability, accuracy, repeatability, and most importantly reliability all depend on the check valves. ASI’s spring loaded valve design provides extremely rapid response that will work efficiently at any flow rate from nanoliters/min up to liters/minute, and at any pressure from 0 PSI up to 30,000 PSI. This also means that the valves will make any pump self-priming – the valves will keep functioning in either air or solvent.

ASI has developed a check valve for almost any application in HPLC and other metering pumps:
