6. Check the tip cone for foreign particles.
7. Grease the cleaned parts with the lubricant recommended by the manufacturer.
8. Reassemble the pipette components.
0.2-2µl & 1-10 µl: First, slide spring 22, o-ring
support 23 and o-ring 24 on the tube 21. With
the 0.2-2µl model insert the tube 27 into the
tube 21. Then slide the spring 13, spring
support 16 and tubes 17 and 18, bigger o-ring
19 and smaller o-ring 20 back on the piston.
Compress the spring with fingers by pressing
piston and spring support 16 against each
other and slide the tube 21 with rest of the
parts on the piston. Hold the spring compressed
and carefully slide the entire assembly into the
tip cone and release the spring.
2-20 µl & 5-50 µl: Slide the spring 13, spring
support 16 and tubes 17 and 18, bigger o-ring
19 and smaller o-ring 20 back on the piston.
Compress the spring with fingers by pressing
piston and spring support 16 against each
other and slide the bigger o-ring 19, smaller
o-ring 20, spring support 21 and the spring 22 (smaller diameter against spring support 21)
on the piston. Hold the spring compressed and carefully slide the entire assembly into the tip
cone and release the spring.
10-100 µl & 20-200 µl: Slide the spring 13, spring support 16 and o-ring 17 back on the
piston. Slide the entire assembly into the tip cone.
100-1000 µl: Put the o-ring 17 and support ring 16 to the tip cone. Slide the spring 13 on the
piston and slide the entire assembly into the tip cone.
9. All: 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 first clockwise tight by hand,
then do the final tightening with the service tool.
10. Reassemble the tip ejector.
0.5-5 ml & 1-10 ml pipettes
1. Press the tip ejector.
2. Rotate the tip ejector 10
counterclockwise to open it.
3. Disassemble the lower part of the tip
ejector 14 (snap fitting).
4. Turn the cylinder 13 counterclockwise
and pull out the tip cone assembly.
5. Remove the cylinder 13 by pressing the snaps fittings
of the cylinder.
5. Clean and regrease the O-ring 12 and cylinder 13.
7. Assemble the parts in the opposite order of disassembly.
Sterilization
The tip cone module can be sterilized by autoclaving it at 121°C (252°F) (2 ata)
for 20 minutes. You can use steam sterilization bags if needed.
After autoclaving the module must be cooled to room temperature for at least two hours. Before
pipetting, make sure that the module is dry. We recommend that you check the calibration after
every sterilization cycle.
