Watson-Marlow 120S Variable-Speed Single-Channel Pump System

Compact pump systems deliver accuracy and repeatability to optimize your fluid handling process

Easily maintain fluid integrity using peristaltic pumps. Only the bore of the tubing contacts the fluid, eliminating the risk of the pump contaminating the fluid or the fluid contaminating the pump. Peristaltic pumps are great for use with most liquids, including viscous, shear-sensitive, corrosive, and abrasive fluids.

Manual control drives include a single-channel pump head for flow rates up to 170 mL/min*—select from 2-roller, 4-roller, or 4-roller flip-top models. Easily adjust speed, start/stop, and direction from the keypad. Adjust speed in 1 rpm increments using the up/down arrows. Press the MAX key for rapid priming; AUTO START for automatic power recovery. Use the keypad lock feature to prevent any unwanted changes to pump settings. A smooth, IP31-rated housing encases a maintenance-free, brushless motor for quick and easy cleaning. Contact us for free technical application support on pump and tubing selection.
