Trouble Shooting; Spare Parts - Thermo Scientific Finnpipette F1 Guide D'utilisation

Sterilization
The tip cone assy of a single channel pipette can be repeatedly autoclaved at 121°C (252°F)
(2 ata) for 20 minutes. All other parts and the multichannel pipettes are not autoclavable. After
autoclaving the tip cone assy must be cooled to room temperature for at least two hours. Before
pipetting, make sure that the tip cone assy is dry. We recommend that you check the calibration
after every sterilization cycle.
Autoclavable parts:
Part number 42: single channel tip cone assy
Excluding part number 10 and 14 on 0.5-5ml and 1-10ml models
The part numbers are presented in section Spare Parts.
