Decontamination
Autoclaving
The body (handle) of the pipette is not autoclavable.
However, after separation from the body, any of the
internal components of the volumetric module may
be autoclaved individually: ejector-cover, ejector, con-
necting nut, tip-holders, pistons, springs and washers
(except O-rings).
1) Clean the parts to be autoclaved, especially the
tip-holders.
2) Put the parts in an autoclaving sack.
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 tem-
perature.
Chemical Decontamination
You may choose to decontaminate your pipette
chemically, in accordance with your own procedures.
Whatever decontaminant you use, check that it is
compatible with the plastics used in the construction
of the pipette (see page 26).
Body (Handle)
1) Wipe the body (upper part) of the pipette with a
soft-cloth or lint-free tissue impregnated with the
chosen decontaminant.
2) Wipe the upper part of the pipette with a soft-cloth
or lint-free tissue impregnated with distilled water
or sterile water.
Volumetric module (lower part)
The following components only can be immersed in
a decontaminant solution: ejector-cover or tip ejector,
connecting nut, tip-holder, piston, and springs. The O-
ring, washer and washer clip should be replaced.
