The Model 720 Compact Peristaltic pump is a stand-alone pump series with flow rates of 0.02 to 12 ml/hr (Low Flow), 0.2 to 145 ml/hr (Mid-Flow) and 2 to 1100 ml/hr (High Flow). It is an ideal pump for applications which require limited size or weight, low EMI interference, the versatility of single and dual tubes sets (see table below) and/or external analog control.

An internal 9V lithium battery (supplied) will run the pump for up to 30 hours, protecting your experiments in the event of a power failure. Due to its power requirements, the high flow version is not available with battery backup.

The pump is typically powered by a 1.25 V internal reference voltage. An external reference voltage can be used to regulate flow rate and direction (pump direction can only be reversed by analog control). Under external control the speed dials serve as voltage attenuators to limit the external voltage to ±1.25 volts.

Supplied complete with 9 V lithium battery and wall-mounted AC adapter. Tube sets are available separately. Please see our website or contact customer service for more information. When using with saline and most drugs, use silicone tubing. For use with solutions containing fats, such as IV diets, use C-FLEX® tubing. For use with petroleum-based fluids, use VITON® tubing.
