VWR Pumps, Variable Flow - Model 54856-070 - Each : 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 degrees C (-80 to 500 degrees 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. Dimensions: 16.8L x 12H x 11.5D cm (65/8 x 43/4 x 41/2") Shipping Weight: 0.57 kg (1.25 lbs.)
