Sterilization - Thermo Scientific F1-ClipTip User Manual

7.2.7 Cleaning and reassembling multichannel pipettes
See the cleaning instructions in Section 7.2.2 "Single channel pipettes". Check the volume-specific
reassembling of the piston assemblies starting on page 23. The pipette is assembled in the reverse
order to disassembling. Note that the ejector link 24 must be in the down position simultaneously
with the tip ejector 23 (page 26). Clean and lubricate the holder spring 13 before assembling.
NOTE!
To ensure even performance between all channels in a multichannel
pipette, all tip cones have to be changed at the same time, if any of
them needs to be changed. Don't mix tip cones of different packages,
because one bag contains a matched set of tip cones. Place aligning
studs to the same side when assembling the module (Picture 18).
Make sure that the tip fittings are aligned in same level, adjust if necessary.
Before autoclaving, disassemble the tip fitting from the tip cone and autoclave them separately. After
autoclaving, the tip cone and tip fitting must be cooled to room temperature for at least two hours.
When reassembling, make sure that the tip cone and tip fitting are dry. We recommend checking
the calibration after every sterilization cycle. The effectiveness of the autoclaving must be verified
by the user.
8.1 Autoclavable parts:
Single and multichannel pipettes:
- Tip fitting 5 and 30
- Tip fitting O-ring (5.1)
Single channel pipettes:
- Tip cone assembly (42)
Parts can be repeatedly autoclaved at 121°C (252°F) (2 ata) for 20 minutes.
