Pump

Steady high-pressure
pulsation-free flow

Stream LC photo
For years solvent delivery pumps in HPLC was dominated by complex, expensive, and none-reliable reciprocating multi plunger devices. With proliferation of small-bore columns the needs for continuous unlimited flow is diminished. Now a small syringe based pump can provide sufficient amounts of mobile phase for almost any narrow and small bore application. Since syringe flow is inherently pulsation free, there is no need for bulky dampeners mixers and precision check valve arrangements. Refill time is reduced for a few seconds prior to each injection. Two pumps when connected provide high pressure mixing precision gradient flow with zero delay volume mixing at high pressure.
