Setting the Flow Rate.
Enter the desired value into the software and then press the “Set Button”.
The pump will accept values ranging from -500 µL/min to 500 µL/min in the Purge Mode. A negative flow rate
means that the flow is being reversed and the pump is aspirating liquid. A positive flow rate means that the
pump is delivering liquid. The software will not register the flow rate entered until the user clicks the “Set”
button. For negative values caution should be used with flow rate to
avoid cavitation and degassing
. In Flow
Control Mode, the upper and lower flow range will be limited relative to the pump model.
Pump “Stop” versus setting Flow Rate to 0 µL/min.
When the “Stop” button is selected in the
software, the power to the motor is turned off. In contrast, setting the flow rate to 0 µL/min keeps the pump
in Flow Control Mode, and the pump will continue to compensate to maintain a flow of 0 µL/min. The ability
to maintain a flow rate of 0 µL/min is useful when multiplexing more than one pump as the pump set to 0
µL/min will compensate for changes in backpressure, eliminating the possibility of back flow.
Timer.
The software has a built-in timer that will allow the user to have the pump deliver a flow rate
for a desired period of time. When the time limit has been reached, the software sets the flow rate to 0
µL/min. This feature is useful if a user wants the pump to run for a period of time, but to stop before the user
returns to the lab.
