Compact Peristaltic Pump (Model 720)
The Instech Model 720 Compact Peristaltic Pumps are a stand-alone pump series with flow rates of 0.2 µl/min to 18 ml/min (0.04 to1100 ml/hr) depending upon the pump and tubing selected.
These pumps deliver the accurate low flow rates of syringe pumps without the limits on delivered volume. They are ideal for animal IV infusion, tissue perfusion, and other low-flow laboratory applications. Choose the motor and tube set that best matches your flow requirements.

Features
- Compact and versatile peristaltic pump
- Continuous infusion
- Battery back-up (30 hrs)
- Minimal electromagnetic radiation
- Choose from ultra-low, low, mid, or high flow
Instech offers this pump with four different motors; choose the motor and tube set that best match your flow rate requirements. In general, use the standard 61-0098 for flows between 0.05 and 1 ml/min, the lower flow 72-4048 for rates between 5 and 100 µl/min, the ultra low flow 72-4049 for rates as low as 0.2 µl/min, and then the higher-flow 72-0001 for rates up to18 ml/min (1 l/hr). With a given tube set, the pump performs best over a 10:1 flow control range.

Operation and Use
The pump’s analog circuitry has been carefully designed to minimize electromagnetic radiation; for this reason, the pump is often used for tissue perfusion even in the presence of sensitive intracellular recordings. It is also an ideal pump for applications which require limited size or weight, the versatility of single and dual tubes sets and/or external analog control.
An internal 9 V lithium battery (supplied with PC4 61-0098, PC4 72-4048 and PC4 72-4049) will run the pump for up to 30 hours, protecting your experiment in the event of a power failure. Due to its power requirements, the high flow version (PC4 72-0001) 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.
Recommended Tubing
Tube sets must be purchased separately. Please contact technical support if you need assistance choosing the right tube set. For use 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.
