Description
The Harvard 33 Syringe Pump offers continuous infusion or withdrawal, 24 hours a day, 365 days a year with the accuracy and low flow of a Harvard syringe pump.

The Harvard 33 Syringe Pump is a breakthrough in pumping technology. The 33 has two independent pumping channels linked through hardware and software. When combined with a valve box, it provides the continuous delivery of a peristaltic or piston pump with the accuracy, absence of pulsation and low flow rates of a syringe pump.

The Harvard 33 Twin Syringe Pump opens up whole new pumping possibilities.
These are some of the applications of this pump:
• The injection of dyes, perfumes and flavoring in industrial applications
• Applications with liquids or viscous materials in micro-manufacturing
• Continuous injections of reactants into reactor vessels
• Simultaneous samplings from two sites
• Continuous injection for long term toxicology testing

Several modes of operation are available to accommodate a range of setups and experimental protocols. A unique movable limit switch mechanism is used to change direction or stop operation of the pump depending on the mode of operation.
