Cleaning And Sterilization; Pipette Kit And Accessories - Labnet BioPette PLUS BPP2 Instuction Manual

If you find an increase in the pipetting force, which
may happen after repetitive autoclaving of the pipette:
Remove the tip ejector. Unscrew the shaft nut, and
then remove the shaft, piston assembly, seal and
O-ring. Rinse the removed parts in distilled water and
dry. Lubricate the internal surfaces of the seal and
O-ring with lubricant that has been included with each
pipette. Reassemble the pipette in opposite order.
Note: All parts of the pipette can be autoclaved (see
Section 10)
The shaft of the 5000 and 10000 models should be
autoclaved without the filter.
If the problem continues after carrying out the above
steps, contact your Labnet representative.
Before returning the pipette, please ensure that the
pipette is completely free of any chemical, radioactive or
microbiological contamination which could pose a threat
during transport and repair. As far as it is possible, clean
the pipette.

10 - CLEANING AND STERILIZATION

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. The remaining parts removed from the
pipette during pipette disassembly may be washed with
distilled water or isopropyl alcohol.
Sterilization:
The pipette can be sterilized in an autoclave at 121°C for
20 minutes. After sterilization, the pipette should be dried
and cooled to room temperature.

It is recommended:
- to sterilize the pipettes in autoclave with an initial vacu-
um and drying cycle,
- prior to sterilization unscrew the shaft nut slightly in the
BPP2-BPP1000 pipettes, and unscrew the shaft slightly
in the BPP5000 and BPP10000. After autoclaving these
parts should be screwed tight again.
- to set the locking ring in lower (unlocked) position prior
to sterilization.
The precision of the results should not alter if the pipet-
ting process and autoclaving are carried out as
described in this manual. Because a slight change in the
accuracy of the dosage may occur, it is recommended to:
- check the calibration of the pipette after the initial first,
third and fifth autoclaving cycles and then after every 10
autoclaving cycles.
