soft-cloth and brushes.
4/ Rinse the individual components with distilled water.
5/ Leave the parts to dry by evaporation or wipe them with a clean soft-cloth or lint-free tissue.
6/ Lubricate the piston and reassemble the pipette according to the instructions given in chapter 13.
Multichannel models
The following components only can be immersed in a cleaning solution: tip-ejector and ejector
locks.
1/ Remove the tip-ejector
2/ Immerse the tip-ejector and ejector locks in the cleaning solution or wipe them with a soft cloth or

Please note that although the lower part of VWR Electronic multichannel Pipette can withstand a
few number of autoclaving cycles, we do not recommend autoclaving it.
Decontamination
Autoclaving - Single channel models
However, after separation from the body, any of the following components of the volumetric module
may be autoclaved individually: tip-ejector, connecting nut, tip-holders, pistons and seals (except
O-rings).
1/ Clean the parts to be autoclaved, especially the tip-holders.
2/ Put the parts in an autoclaving bag.
3/ Autoclave for 20 minutes at 121°C and 0.1 MPa.
4/ Check that the parts are dry before reassembling the pipette.
5/ Set the pipette aside to stabilize at room temperature for at least 6 hours.
The body (handle) of the pipette is not autoclavable!
The specifications of the pipette must be checked after
autoclaving/disassembling
