DISASSEMBLING ASSEMBLING MuLTIchANNEL PIPETTES
1. Press down the tip ejector.
2. Insert the maintenance pliers under the tip ejector bar to release the
tip ejector.
3. Remove the tip cone module by pressing it with the maintenance
pliers.
4. Press the spring and remove the locking pieces
from the groove. Remove the spring, spring
support and O-ring.
5. Place the maintenance key in the adapter groove
and pull off the adapter.
6. Pull out the tip ejector adapter. Lift the upper
end of the tip ejector bar slightly and push
it back.
Lift out the module spring.
7. Use a screwdriver to remove the four/six screws
in the module cover and lift off the cover.
8. Remove the piston bar and clean the pistons
with a dry nap–free cloth.
9. Clean the tip cones.
10. If needed, replace the seal 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.
Reassemble the tip cone.
5–50 µl and 50–300 µl: Take one piston. Slide cover ring 32 (larger
hole), spring 33, support ring 35, (O-ring 37 bigger 5-50µl) and
O-ring 36 (smaller) onto the piston. Grease the o-rings with the
lubricant recommended by the manufacturer. Slide all the parts into
the tip cone and close the snap joint of the cover ring.
0.5–10 µl: Take one piston. Slide cover ring 32 (larger hole), support
35, O-ring 36 (bigger), O-ring 37 (smaller) and O-ring support 38
onto the piston. Then slide spring 39, spring support 40 (sharp
edges first) and O-ring 41 onto the O-ring sup port 38. Grease the
o-rings with the lubricant recommended by the manufacturer. Slide all the parts into the tip
cone and close the snap joint of the cover ring.
11. Grease the o-rings with the lubricant recommended by the manufacturer.
12. Install the piston bar with pistons and tip cones in the cover and close the cover with the
four/six screws.
13. Place the tip ejector and module spring on the neck of the module. Press the spring below
the tip ejector. Close the tip ejector with the tip ejector adapter.
14. Use the maintenance key to slide the adapter to wider groove in the module neck.
15. Slide the O-ring, spring support and spring onto the piston bar and lock with the
locking pieces.
16. Attach the tip cone module to the handle and the tip ejector adapter to the tip ejector bar.
SErvIcE INSTrucTIoNS for MuLTIchANNEL PIPETTE TIP coNES
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.
