High pressure syringe pump module is
programmable
Users can start or stop the pump, change the pumping direction, change the flow rate, pump a precise volume and stop, pause the pump and even ramp up or ramp down the flow rate
Those looking to incorporate high pressure, accurate and precise dispensing, or fluid addition to a process or instrumentation, should consider this new PHD OEM pumping module says Harvard Apparatus With the Program and Auto Fill buttons, this pump can be programmed with a sequence of pumping steps

Transducers for any isolated tissue application
The Harvard Apparatus Research TRI series isometric force transducers measure the force of contraction of isolated tissues under conditions of constant preload
Users can start or stop the pump, change the pumping direction, change the flow rate, pump a precise volume and stop, pause the pump and even ramp up or ramp down the flow rate.
All of these tasks can be linked together in a sequence providing a powerful tool to simplify and automate complicated pumping processes.
The Auto Fill key is useful when the user would like to deliver a large volume of fluid.
The user sets a target volume and then programs the refill volume for the syringe.
The pump will automatically refill the syringe as many times as required to reach the target volume.
Then the pump will automatically stop.
This process does require the use of a valve.
On the back side of all PHD 22/2000 Syringe Pump are two RS232 ports.
One is for input from a computer and the second is for output when daisy chaining more than one pump together.
The I/O port is a nine-pin D sub connector and is used for TTL control.
Also on the back is the universal power entry module which encompasses the on/off switch, fuse and universal power supply.
This power supply will accept power input from 110 to 240VAC, 50/60Hz.
The mechanical stop collars cause the pump to stop automatically, thus protecting expensive syringes.
