AccuPump2 OEM Syringe Pump - TriContinent


The next generation AccuPump2 OEM Syringe pump is designed to meet the broad needs of the automated liquidhandling market and is a seamless replacement for industry standard pumps using the Cavro® protocol.  A variety of valves, piston seal designs and syringe barrel sizes provide selection and flexibility at a reasonable price and each AccuPump2 syringe pump is manufactured under stringent quality control standards resulting in industry recognized reliability and accuracy.  The TriContinent AccuPump2 provides a low-cost alternative to in-house customized syringe pump designs.

AccuPump2 Syringe Pump with No Valve

Created for use as a sample side of a two-syringe diluter or as a standalone air-displacement syringe pump, the valve-less AccuPump2 syringe pump provides accuracy, precision and long-life reliability.  The AccuPump2 includes a TriContinent motor-driver PCBA which provides ready-to-use interfaces for single or multiple syringe pump use.

AccuPump2 Syringe Pump with Valve

The AccuPump2 OEM syringe pump includes a highly reliable shear valve and is designed for use as the primary syringe pump in a two-syringe diluter system or as a single-syringe diluter/dispenser.  It can be used as a standalone or in combination with other standard syringe pumps.  AccuPump2 includes a TriContinent motor-driver PCBA which provides ready-to-use interfaces for single or multiple syringe pump use.


The two available three-way valves, small and large, have a polycarbonate body with a high-density polyethylene core and can last mote than 1,000,000 cycles in chemically compatible applications.  A nylon valve body is also available.

See TriContinent's BasePump / AccuPump2 for a syringe pump similar to the AccuPump2 but without control electronics.  The BasePump without electronics is best for those instrument manufacturers who have experience driving motors or are planning to develop their own control electronics.
