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.

• Digital display
• Flow rates can vary from a low of 0.005mL/min. to as much as 600mL/min., depending on the pump model
• Ideal for use with conductivity flow-thru cells, liquid chromatography, collecting fractions, pH/circulating fluids or buffers in baths, and moving corrosive materials
• Four different tubing sizes ( 1/16", 3/32", 3/16", 1/4") and corresponding fittings/nipples provide fine resolution with a wide flow range; revolution of one roller delivers a precisely measured volume specific to the tubing size and motor speed
• Fluid contacts only tubing for contamination-free pumping
• Tubing may be used with fluid temperatures from –80 to 500°F (–62 to 260°C)
• May be used with up to 120 feet of tubing for remote sampling

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.
