Compact, variable-flow, bi-directional, self-priming, peristaltic pumps offer precise flow deliveries. Ideal for use with conductivity flow-thru cells, liquid chromatography, collecting fractions, pH/circulating fluids or buffers in baths, and moving corrosive materials. They provide outstanding flow control and flexibility for transferring and dosing liquids. Fluid contacts only the tubing for contamination-free pumping. Flow rates are from 0.005 milliliters per minute to 600 milliliters per minute. Variable-speed flow control and five different tubing sizes provide fine resolution with a wide flow range. The revolution of one roller delivers a precisely measured volume specific to the tubing size and motor speed. May be used with up to 120 feet of tubing for remote sampling. Tubing may be used with fluid temperatures from -80 to 500°F (-62 to 260°C). Use with food, pharmaceuticals, and other critical solutions. The tubing may be sterilized by autoclave. Unit pumps liquids and gases. Pumping dry does not harm the pump. Pump has a purge/prime switch for high-speed emptying/filling. It also reverses at the touch of a switch for ease in draining tubing. Three rollers reduce flow pulsation, prevent siphoning, and eliminate the need for check valves. There are no valves to clog, no seals to leak. The 120-VAC CSA-approved wall power supply ensures that a safe 12 volts drive the pump motor. Comes with a battery connector for portable use with any 9 or 12-volt battery. Pump draws so little power it will run for five months on a car battery. Accessory Chemical-Resistant Check Valves Tubing barbed check valves are constructed of chemical-resistant Kynar® body and Viton® valve for an inert high purity smooth and clear flow path. Use with acids, bases, water, chemical processing, and alcohols. Use for liquids, gases, pressure, and vacuum applications. Operating ranges are 0 to 50 PSI and -40 to 126°C. Autoclavable, zero maintenance, 1-1/4 inch length unit installs in any position. Prevents damage to equipment, pumps, and flow systems by preventing backflow. Supplied with silicone tubing, and polypropylene fittings/nipples, 115-VAC wall power supply, and an accessory battery connector (battery not supplied). Packaged in a chemical-resistant ABS plastic case. Size is 6-5/8 x 4-3/4 x 4-1/2 inches and weight is 1-1/4 pounds. One-year warranty. Cat.
