The Harvard 33 Dual Syringe Pump offers continuous infusionorwithdrawal, 24 hours a day, 365 days a year with the accuracyandlow flow of a Harvard syringe pump.

TheHarvard 33 Dual Syringe Pump is a breakthroughin pumpingtechnology. The 33 has two independent pumping channelslinkedthrough hardware and software. When combined with a valvebox, itprovides the continuous delivery of a peristaltic or pistonpumpwith the accuracy, absence of pulsation and low flow rates ofasyringe pump.

TheHarvard 33 Dual Syringe Pump opens up whole newpumpingpossibilities. These are some of the applications ofthispump:

• The injection of dyes, perfumes and flavoring in industrial applications

• Applications with liquids or viscous materials in micromanufacturing

• Continuous injections of reactants into reactor vessels

• Simultaneous samplings from two sites

• Continuous injection for long term toxicology testing

Several modes of operation are availabletoaccommodate a range of setups and experimental protocols. Auniquemovable limit switch mechanism is used to change direction orstopoperation of the pump depending on the modeofoperation.

Reciprocal/Parallel Mode - Syringe mechanismscanrun in the same or opposite directions (i.e.bothinfusing/withdrawing at the same time or one infusing and theotherwithdrawing)

Proportional Mode - Different flow ratesandsyringe diameters can be set for eachsyringemechanism

AutoStop Mode - Pump stops operation when alimitswitch is activated.

Continuous Run Mode - When a limit switchisactivated each syringe mechanism reverses direction.

Thepump has high pressure capability and TTL andRS-232 interface fordata acquisition and control.

Thecommunication ports enable daisy-chaining of upto 100pumps.
