3. Remove the Clip trigger 8 and Clip trigger spring 9.
4. Turn the tip cone 11 counterclockwise with the service tool 1.
There are two slots in the service tool: the smaller one for pipettes under 300 μl and the bigger
one for pipettes over 300 μl.
5. Pull out the piston assembly and other parts from the handle with the tip cone 11.
Then turn the tip cone upside down and tap all parts from it.
You can check the parts of each specifi c pipette from the pictures starting on page 23.
Remember to keep all parts in order on the table for reassembly.
7.2.3 Cleaning and reassembling single channel pipettes
- General maintenance instructions can be found on page 11.
- Clean the piston, the piston spring and the O-rings with a dry napless cloth.
- Check the tip cone for foreign particles or dirt. Immerse it in a suitable cleaning solution.
Dry before assembly.
- Grease the cleaned parts with the lubricant that comes with the pipette.
- The pipette is assembled in the reverse order to disassembling. Check the volume-specifi c
reassembling of the piston assemblies starting on page 23.
Piston reassembly procedures
1-10μl, 1 / 5 / 10μl Fixed
- First slide the spring 21, O-ring support 22 and O-ring 23 onto the tube 20.
- Then slide the spring 13, the spring support 16 and tube 17, the bigger O-ring 18 and the smaller
O-ring 19 back onto the piston 12.
- Compress the spring 13 with your fi ngers by pressing the piston and the spring support 16 against
each other, and then slide the tube 20 with the remaining parts onto the piston.
- Hold the spring 13 compressed and carefully slide the entire assembly into the tip cone 11,
and then release the spring.
- Put the spring 15 and support 14 on top of the tip cone and carefully insert the tip cone assembly
to the handle. Attach the tip cone by turning it fi rst clockwise tight by hand, then do the fi nal
tightening with the service tool.
- Reassemble the Clip trigger spring 9 and Clip trigger 8. Assemble the tip fi tting according to
instruction in 7.2.4.
Reassemble the tip ejector 10.
2-20μl, 20μl Fixed, 5-50μl 25 / 50μl Fixed
- Slide the spring 13, spring support 16 and tube 17 back onto the piston 12.
- Compress the spring 13 with your fi ngers by pressing the piston 12 and the spring support 16
against each other, and then slide the bigger O-ring 18, the smaller O-ring 19, the spring support
20 and spring 21 (smaller diameter against spring support 20) onto the piston.
- Hold the spring 13 compressed and carefully slide the entire assembly into the tip cone 11,
and then release the spring.
- Put the spring 15 and support 14 on top of the tip cone and carefully insert the tip cone assembly
to the handle. Attach the tip cone by turning it fi rst clockwise tight by hand, then do the fi nal
tightening with the service tool.

- Slide the spring 13, spring support 16 and O-ring 17 back onto the piston 12.
- Slide the entire assembly into the tip cone 11.
- Put the spring 15 and support 14 on top of the tip cone and carefully insert the tip cone assembly
to the handle. Attach the tip cone by turning it fi rst clockwise tight by hand, then do the fi nal
tightening with the service tool.
