精密雙注射泵Pump 33主要特點(diǎn)：

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.
