- Put the O-ring 17 and support ring 16 onto the tip cone 11.
- Slide the spring 13 onto the piston 12 and 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.
- Reassemble the tip ejector 11. Assemble the tip fi tting according to instruction in 7.2.4.
7.2.4 Reassembly of tip fi tting 5 and O-rings 5.1 and 5.2
- Place the tip fi tting onto the tool end with a metal rod so that the screw end is facing
upwards.
Place the O-ring into the rod above the tip fi tting or make sure that the O-ring is at the bottom of
the cylinder's screw end. We recommend using a new O-ring during each maintenance.
Align the tool with the cylinder and carefully screw the tip fi tting in by turning the tool clockwise.
Stop tightening when you feel resistance.
Rotate the tip fi tting tool and tighten the tip fi tting by using the end without a metal rod.
Check that there is no gap between tip fi tting and cylinder (Picture 13).
- Fit in a new O-ring 5.1.
Be careful not to overtighten the tip fi tting. This may damage the thread in the pipette.
NOTE! If the tip fi tting is tightened using the end with the metal rod of tip fi tting tool, the tool will
start to slip. This may disform the tool and make it more diffi cult to use.
7.2.5 Disassembly of multichannel pipettes
1. Remove and discard the O-ring and remove the tip fi ttings (Picture 8) with the Tip fi tting tool
(Picture 9).
We recommend replacing the O-ring during each maintenance.
2. Press the tip ejector 4.1 down, whereupon it presses the tip ejector 23 down at the same
time. Keep the ejector cover manually in the down position and let the tip ejector rise to the
normal position, whereupon the parts snap apart revealing a slot 7. If needed, facilitate
lightly by hand.
3. Keep the handle 4 still and insert the second end of the service tool 2 into the slot and turn
clockwise to separate the handle and the module 6. from each other. Loosen until you can pull the
parts apart.
4. Pull the holder spring 13 downwards and remove the two locking pieces 12. Finally, remove
the holder spring carefully ensuring that the spring does not fl y off.
5. Remove the two MCP adapter claws 44/45 and pull the MCP adapter 46 away. Remove the
MCP spring base 43 by pulling upwards.
