Maintenance - Thermo Scientific Finnpipette F2 Guide D'utilisation

When the Finnpipette F2 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 64.
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
Annual pipette usage varies significantly among laboratories, and the
types of substances being aspirated and dispensed also vary tremendously
among laboratories. In order to maintain proper care of the pipette, it is the
laboratory's responsibility to develop a proper maintenance program that
meets its specific needs and requirements.
The servicing procedure starts with the disassembly of the pipette.
1-1000 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 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.
100-1000µl: 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 thetip cone.
