Syringe Pump

A syringe pump is a precision instrument that delivers accurate, continuous, and pulsation-free fluid flow by mechanically driving a syringe plunger at a controlled rate, used for drug infusion, microinjection, and perfusion studies.

A stepper motor drives a lead screw that advances the syringe plunger at a precisely controlled rate. Flow rate is set digitally and can range from nanoliters to milliliters per minute depending on syringe size and pump resolution.

Syringe pumps are used for stereotaxic microinjection of drugs into brain regions, continuous IV drug infusion in pharmacokinetic studies, and precise fluid delivery in microfluidics and organ-on-chip experiments.
