Maintenance - Thermo Scientific Finnpipette F1 Guide D'utilisation

When the Finnpipette F1 is not in use, make sure it is stored in an upright position. We
recommend a Finnpipette stand for this purpose.
The part # refer to exploded views beginning at page 63.
Short-term service
The pipette should be checked at the beginning of each day for dust and dirt on the outside
surfaces of the pipette.
Particular attention should be paid to the tip cone. No other solvents except 70 % ethanol should
be used to clean the pipette.
Long-term service, single channel pipettes
If the pipette is used daily it should be checked every three months. The servicing procedure
starts with the disassembly of the pipette.
2-1000 μl pipettes
1. Press the tip ejector.
2. Rotate the tip ejector 11 counterclockwise and pull it out.
3. Turn out the tip cone counterclockwise with the service tool.
4. Pull out the piston and other parts. Push out with piston the rest of the
piston assembly. Then turn the tip cone upside down and tap all parts
from tip cone. Remember keep all parts in order on table for reassembly.
5. Clean the piston, the piston spring and the O-rings with a dry napless cloth.
6. Check the tip cone for foreign particles.
7. Grease the cleaned parts with the lubricant that comes with the pipette.
8. Reassemble the pipette components.
0.2-2μl, 0.5-5μl & 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 fi ngers 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 fi ngers 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.
100-1000μl: 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
