These microprocessor-controlled syringe pumps are designed for applications requiring low, pulse-free flow rates. Dispensed volume is continuously displayed, and when the preset volume has been dispensed, these small infusion syringe pumps shut off automatically. These inexpensive pumps combine precision and simplicity with durability. Additional features in select models include a simple menu-driven setup, permanent memory of last-used settings, and continuous dispense volume display. Pumps can have either single-syringe or multiple-syringe setups, depending on user needs. VWR offers a wide range of full featured programmable syringe pumps with user defined flow rates and selectable target volume.
