Harvard Apparatus PHD 2000 Syringe Pump

Harvard Apparatus prides itself on building the most reliable syringe pumps on the market and Harvard Apparatus pumps are quite literally the most popular syringe pumps in the world. You can’t get much more of an endorsement than that.

The Harvard Apparatus PHD 2000 is an infusion only syringe pump that is suited for applications that require high accuracy and low rates. This unit is not programmable but does have a RS-232 port for PC communication capability. The Harvard PHD 2000 has two modes of operation: PUMP, a continuous run until the syringe is empty, and VOLUME, which runs until a specified volume has been pumped.The micro stepping motor and control software give the lowest flow rates ever, down to 0.0001 µl/hour. It is also incredibly quiet so it won’t disturb experimental subjects. The programming functions of Harvard PHD 2000 pump provide powerful capabilities for advanced experiments. While in program mode this pump can perform several tasks at a predetermined time or when prompted by a signal from an external device, including start or stop pumping, change flow rates, pump a precise volume and stop, pause operation, and ramp up or down flow rates.

Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.
