精密双注射泵Pump 33主要特点９�/strong>

The Harvard 33 Dual Syringe Pump offerscontinuous infusion or withdrawal� 24 hours a day� 365 days a yearwith the accuracy and low flow of a Harvard syringe pump.

The Harvard 33 Dual Syringe Pump is a breakthrough in pumpingtechnology. The 33 has two independent pumping channels linkedthrough hardware and software. When combined with a valve box� itprovides the continuous delivery of a peristaltic or piston pumpwith the accuracy� absence of pulsation and low flow rates of asyringe pump.

The Harvard 33 Dual Syringe Pump opens up whole new pumpingpossibilities. These are some of the applications of this pump:

? The injection of dyes� perfumes and flavoring in industrialapplications

? Applications with liquids or viscous materials inmicromanufacturing

? 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 ofsetups and experimental protocols. A unique movable limit switchmechanism is used to change direction or stop operation of the pumpdepending on the mode of operation.

Reciprocal/Parallel Mode - Syringe mechanisms can run in the sameor opposite directions (i.e. both infusing/withdrawing at the sametime or one infusing and the other withdrawing)

Proportional Mode - Different flow rates and syringe diameters canbe set for each syringe mechanism

AutoStop Mode - Pump stops operation when a limit switch isactivated.

Continuous Run Mode - When a limit switch is activated each syringemechanism reverses direction.

The pump has high pressure capability and TTL and RS-232 interfacefor data acquisition and control.

The communication ports enable daisy-chaining of up to 100pumps.
