Product Category Description:

These variable flow peristaltic pumps provide precise delivery. They are compact and ideal for applications in liquid chromatography, fraction collection, fluids/buffers circulation in baths, and corrosive material movement. Bidirectional, self-priming pumps provide outstanding flow control and flexibility for transferring and dosing liquids. Fluid contacts only the tubing for contamination-free pumping.

Flow rates range from 0.005 to 600mL/min. Variable speed flow control and five tubing sizes allow a wide flow range and fine resolution. Revolution of one roller delivers a precisely measured volume specific to the tubing size and motor speed.

Tubing can be used with fluids –62 to 260°C (–80 to 500°F). Tubing is autoclavable for use with food, pharmaceutical, and other critical solutions. Pumps liquid or gas, and pumping dry is not harmful to unit. The pump has a purge/prime switch for high speed emptying/filling. It also reverses at the touch of a switch for easy draining. Three rollers reduce flow pulsation, prevent siphoning, and eliminate the need for check valves. There are no valves to clog or seals to leak. Housed in a chemical-resistant ABS plastic case. For 115V operation.
