Repair and maintenance of the pipettor
Cleaning:
External surfaces of the pipetting pushbutton, the ejector
pushbutton, the handgrip, the shaft nut and the adjust-
ment knob may be cleaned using a cloth dampened in
isopropyl alcohol. Remaining parts removed from the
pipettor during pipettor disassembly may be washed
with distilled water or isopropyl alcohol.
Sterilization:
The pipettors can be sterilized in the autoclave at 121°C
for 20 minutes. After sterilization, the pipettor should be
dried and cooled down to room temperature.
It is recommended:
- to sterilize the pipettors in autoclave with an initial vacuum
and drying cycle.
- prior to sterilization to unscrew the shaft nut slightly in
the VWR2-VWR1000 pipettors, and unscrew the shaft
slightly in the VWR5000 and VWR10000. After autoclaving
these parts should be screwed tight again.
- to test pipettor calibration every 10 sterilization cycles.
Note: VWR pipettors should be autoclaved with the
filter removed (VWR5000 and VWR10000).
After autoclaving, check that the shaft nut is tightly
fitted to the pipettor handle.
