Dual Syringe, Programmable Touch Screen, Continuous Flow, Push-Pull Pump

Push-Pull syringe pump. Accommodate two syringes for infusion and two syringes for withdrawal. These models support infusion and withdrawal simultaneously at user defined flow rates and with selectable target volumes to control the total volume pumped. They also support infuse only, withdraw only, infuse/withdraw/ withdraw/infuse and continuous mode, user-defined flow rates with selectable target volumes.

The 270P Model allows user defined configurations/programs of up to 800 steps. Up to 40 programs of 20 steps each step can be stored in memory.

 

A version with 0-10 VDC Analog Control is also available.
