HPLC Syringe Pump

SIELC’s Alltesta™ Advanced High Pressure Syringe Pump

Alltesta syringe pump was designed to produce a steady high pressure pulsation-free flow. For years, solvent delivery pumps in HPLC have been dominated by complex, expensive, and non-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 applications. 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 less than a minute prior to each injection. Two pumps when connected provide high pressure mixing precision gradient flow with zero delay volume mixing at high pressure.

The pump features communications capability for integration with other instrumentation through the USB virtual serial port.
