Trouble Shooting - Thermo Scientific Finnpipette Guide D'utilisation Et D'entretien

STERILIZATION
The entire pipette can be sterilized by autoclaving it at 121°C (252°F) (minimum 20
minutes). No special preparations are needed for autoclaving. You can use steam
sterilization bags if needed.
After autoclaving the pipette must be cooled to room temperature for at least two hours.
Before pipetting, make sure that the pipette is dry. We recommend that you check the
calibration of after every 25th sterilization cycle.
