变速小型蠕动泵 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.管可用于与流体–62到260°C（–80到500°F）。高压油管是用于食品，制药，和其他关键的解决方案。泵的液体或气体，抽干不是有害的单位。该泵具有高速排空/填充吹扫/主要开关。它也能在个简单的排水开关触点。三辊减少流量脉动，防止虹吸，并消除为止回阀的需要。无阀堵塞或密封泄漏。坐落在个耐化学腐蚀的塑料盒。
Ordering Information: Pumps come ready-to-use ａnd are supplied with silicone tubing （sizes 1/16", 3/32", 3/16", ａnd 1/4" I.D.）, polypropylene fittings/nipples, 115V wall power supply, ａnd an accessory battery connector （9V battery not supplied）. Replacement tubing ａnd tubing sets available separately.
