Watson-Marlow Peristaltic Pump 120S – 120V (1 each)

Easily maintain fluid integrity using the Watson-Marlow Peristaltic Pump. Only the bore of the tubing contacts the fluid, eliminating the risk of the pump contaminating the fluid or the fluid contaminating the pump. The pump is perfect for use with most liquids, including viscous 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. Operate the pump from 1 to 200 rpm in 1 rpm increments to achieve flow rates from 0.001 to 120 mL/min. The pump system includes a four-roller pump head that accepts 0.5 to 4.0 mm bore tubing with 1.6 mm wall. The pump head is constructed of acetal roller assembly, aluminum rotor assembly, aluminum track, and stainless steel hardware. *Flow rate depends on drive rpm, pump head, and tubing size.
