Variable Flow Peristaltic Pumps

This Variable Flow Peristaltic Pumps precisely meters dosing and fluid transfer. The variable speed motor yields flow rates of 0.03 mL/min to 85 mL/min and the reverse switch changes direction of the flow. It accepts 5 tubing sizes for excellent resolution over the entire flow range.

A three-roller design reduces flow pulsation, prevents siphoning, and eliminates check valves. It pumps liquids and gases and dry operation will not harm the pump. The purge/prime switch allows high-speed emptying/filling.

The pump includes silicone tubing (sizes 1/50", 1/16", 3/32", 3/16", and 1/4" I.D.), polypropylene fittings/nipples, auxiliary battery connector (battery not included) and cord with the plug. The compact ABS plastic case measures 6 5/8 x 4 3/4 x 4 1/2". It operates on 115 V, 60 Hz or 9 V battery (not supplied).
