Harvard 33 Twin Syringe Pump Standard Infuse/Withdraw

Description

Harvard 33 Twin Syringe Pump  Standard Infuse/Withdraw
The Pump 33 Twin Syringe Pump is the only pump in the Harvard Apparatus had line that has 2 independent motors. It is like having 2 pumps one chassis. Both motors can infuse, withdraw or infuse and withdraw simultaneously.
Two independent pumps in a single package
• Operate each pump independently at its own flow rate to either infuse or withdraw
• Synchronize the two pumps for all types of exchange
procedures and dilutions of identical amounts
• Deliver or withdraw continuously, 24 hours a day
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.
• Reciprocal/Parallel Mode - Syringe mechanisms can run in the same or opposite directions (i.e. both infusing/withdrawing at the same time or one infusing and the other withdrawing)
• Proportional Mode - Different flow rates and syringe diameters can be set for each syringe mechanism
• AutoStop Mode - Pump stops operation when a limit switch is activated.
• Continuous Run Mode - When a limit switch is activated each syringe mechanism reverses direction.
The pump has high pressure capability and TTL and RS-232 interface for data acquisition and control. The communication ports enable daisy-chaining of up to 100 pumps.
