Trouble Shooting - Thermo Scientific Finnpipette Bedienungsanleitung

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
0.5-1000 µl pipettes after every 25th sterilization cycle and of 1-10 ml pipettes after every 10th
sterilization cycle.
The table below lists possible problems and their solutions.
