Lab Expo Variable Speed Peristaltic Pump 51-VPP400 is a four channeled precise dispensing peristaltic pump to meet laboratory liquid handling needs. Equipped with varied flow range and speed accuracy it 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.
