Standard Infuse/Withdraw PHD 22/2000 Syringe Pumps
The Harvard PHD 22/2000 Advance Syringe Pump family is the most versatile of the pump lines. This pump is available in infuse/withdraw and programmable configurations.
All pumps have RS-232 communications capabilities, but there are also PHD 22/2000 pumps that are programmable directly from the keypad. In addition, a multitude of syringe racks are available to hold 2, 4 or up to 10 syringes. A microliter syringe rack is also available for microliter applications.
Remote versions are also available where the control box and pumping mechanism are separated by a 9.1 meter (30 foot) cable. These models are listed separately on the Harvard Apparatus website.

The Model 720 Compact Peristaltic Pump is a stand-alone pump series with flow rates based on model type and tubing size. 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 with 61-0098, 72-4048 and 72-4049) 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 72-0001 is not available with battery backup.
