主要特点：
EHSY西域品质提供的精密双注射泵性能卓越,能满足您不同工作环境的多种需
求．
The Harvard Dual Syringe Pump is a breakthrough in pumping
technology. The Pump 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 Dual 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 micromanu
-facturing
• 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.
