7.2.7 Cleaning and reassembling multichannel pipettes
See the cleaning instructions in Section 7.2.2 "Single channel pipettes". Check the volume-specifi c
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 as shown in the picture on page 25. 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 16).
Make sure that the tip fi ttings are aligned in same level, adjust if necessary.
Before autoclaving, disassemble the tip fi tting from the tip cone and autoclave them separately. After
autoclaving, the tip cone and tip fi tting must be cooled to room temperature for at least two hours.
When reassembling, make sure that the tip cone and tip fi tting are dry. We recommend checking
the calibration after every sterilization cycle. The effectiveness of the autoclaving must be verifi ed
by the user.
8.1 Autoclavable parts:
Single and multichannel pipettes:
- Tip fi tting (5)
- Tip fi tting 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.
