PERISTALTIC PUMPS
Instech Model 720
64
Harvard/Instech 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 to
1100 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.
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 PC5 61-0098 for flows between 0.05 and
1 ml/min, the lower flow PC5 72-4048 for rates between 5 and
100 µl/min, the ultra low flow PC5 72-4049 for rates as low as
0.2 µl/min, and then the higher-flow PC5 72-0001 for rates up to
18 ml/min (1 l/hr). With a given tube set, the pump performs best over
a 10:1 flow control range.
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 9V lithium battery (supplied with PC5 61-0098,
PC5 72-4048 and PC5 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 (PC5 72-0001) is not
available with battery backup.

Compact Peristaltic Pumps
and Tubing
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.
Tube sets must be purchased separately. Please see our website or 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.
Tube Sets
A wide variety of tube
sizes, tube materials
and connector types
allows you to tailor your
peristaltic pump to your
particular application.
Tube sets typically last
about one month under
continuous operation.
Dual channel tube sets place more stress on the pump than
do single channel tube sets, which may shorten the life of your
pump's motor.
