Updated Pump Head

The Masterflex L/S Easy-Load pump head from Cole-Parmer has an updated design and enhanced features for greater ease of use. The pump head is suited for laboratory, process, and industrial applications. 

This redesigned pump head now pumps 2.3 L per minute at 5 to 6 bar. Enhanced features include improved pressure performance and reduced pulsation with the four-roller design. An improved occlusion-bed geometry reduces tubing wear and lengthens tubing life. Tubing changes are fast with single-thumb actuation. Automatic tubing retention eliminates the need for manual adjustments, thus increasing accuracy and repeatability, as stated by the company. The pump heads can also be stacked for multichannel pumping.

The device has a corrosion-resistant stainless-steel rotor and polytetrafluoroethylene-shielded bearings for improved life expectancy. The pump head works on any Masterflex L/S drive and provides optimal performance when using compatible Masterflex tubing. Models are available with and without open-head sensor functionality. When a pump head with open-head sensor functionality is opened, the drive stops, making it a safer option, according to the company.
