Lab Expo Variable Speed Peristaltic Pump 51-VPP500 is a twenty-four channeled peristaltic pump designed to meet laboratory liquid handling needs. Equipped with a flow range of from 0.00011 to 1700 mL/min and speed accuracy which allows reversible operation to pump in both directions. Provides high levels of volumetric accuracy without contaminating the fluid during the operation. Interchangeable pump heads help in delivering smooth and low pulse flows.
