Description
Laboratory Peristaltic Pump for Dosing and Fluid Transfer
Watson-Marlow 300 Series pumps are compact benchtop peristaltic pumps designed for laboratory dosing, metering, dispensing and controlled liquid-transfer applications.
The range combines chemically resistant ABS construction, IP31 protection, membrane-keypad operation and a digital LCD speed display. Multiple drive and pumphead combinations are available for low-flow, high-flow, single-channel and multichannel pumping requirements.
