System Operation
The vacuum system provides high throughput
fl ow which enables aspiration for applications up to 96 well formats. The
attached inlet trap is provided to inhibit the accidental ingestion of liquid into the pump.
Vacuum level is preset at 26”Hg when the inlet is plugged with a rubber stopper. The vacuum gauge provided allows to check
the vacuum level -- that is pressure below atmospheric. Please keep in mind that atmospheric pressure tends to vary from
day to day. As a result of this variability, the dial vacuum gauge will indicate slightly diff erent maximum vacuum readings
from day to day.
The preset vacuum level may be adjusted by opening or closing the orifi ce. A small leak through the orifi ce is provided
to allow easy restart of the pump if you are turning off then immediately turning on the pump as is found with some cell
harvesting applications.
Adjust the vacuum using the screw located on top of the orifi ce. The deeper vacuum is particulary useful for removing sticky
or viscous substance. If you close off the orifi ce, please keep in mind this will lead to restart problems if you are turning off
then immediately turning on the pump. If you encounter a restart problem after closing the orifi ce, you will need to incorporate
into your procedure bringing the cell harvester up to atmospheric prior to restarting of the pump.
