Long-term service, multichannel pipettes
If the pipette is used daily it should be checked and lubricated
every three months.
1. Place the service tool head#1 between ring 15 and ejector 23. Push the tool
until the partssnap from each other.
2. Check that the ejector lever is in up position and pull down the tip ejector part
of the module. Place the service tool head#2 in the hole of adapter tube 46.
3. Open the upper end of the tip ejector slightly and remove the tip ejector.
4. Screw out the module of the handle.
5. Pull out the module spring 19 and clip 22.
6. Press the spring 13 and remove the locking pieces 12 from

10. If needed, service the tip cones:
16-channel 1-10µl: The tip cones cannot be serviced, please replace if necessary.
30-300 µl, 10-100µl & 5-50 µl: Open the tip cone by carefully releasing the cover ring from
its snap joint with the screwdriver. Remove all the parts from the tip cone. Clean all the
parts. If needed, replace the o-rings. Take one piston. Slide the spring 33, cover ring 32
(larger hole), spring 34, support ring 35, (o–ring 37 bigger 5-50µl/10-100µl) and o–ring 36
(smaller) onto the piston. Grease the o–ring with the lubricant provided in the pipette
package. Slide all the parts into the tip cone and close the snap joint of the cover ring.
