Operational Description of VERITY® 4020 Single Syringe Pump
the Verity 4020 Syringe Pump has a single syringe and valve. the instrument only
dispenses to the GX-241 Liquid handler probe via the automatic loop injection valve of the
PLC Purification System.
NOTE
It is impossible to dispense to the reservoir.
When aspirating from the probe, it is important to take into account the volume of transfer tubing
connecting the pump outlet to the probe. The liquid aspirated from the probe must never enter the
valve. The maximum volume of liquid that can be aspirated from the probe is limited to the volume
of the syringe, or the volume of the transfer tubing, whichever is smaller.
