Upgradeable pumps allow for changing needs!
Harvard Apparatus can help with changing needs: both the features and the syringe capacity of the PHD22/2000 Syringe Pumps can be upgraded without purchasing a new pump
You 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 programmes 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 Pumps 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 9-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 240 VAC, 50/60 Hz.
The mechanical stop collars cause the pump to stop automatically, thus protecting expensive syringes.
