Sterilization
The entire autoclavable range of pipettors can be sterilized by steam autoclaving at
121°C (252°F), 1 atm for 20 minutes.
The single and multichannel pipettors can be autoclaved without special precautions.
Use of a bag is not recommended in order to improve the drying of the pipettor.
After autoclaving, check the connecting nut is fully tightened and screw it if it is not
the case. The pipettor needs to dry completely and cool down to room temperature.
(1/2 day if your autoclave has a dry cycle or otherwise overnight before use).
The piston does not need to be lubricated after autoclaving, except if grease was
removed during cleaning. Gravimetric checking is recommended after every 5
autoclave cycles for single channel pipettors and after 1 cycle for multichannel
pipettors.
