Maintenance - Thermo Scientific F1-ClipTip 4641170 Instructions For Use Manual

Cautions for incorrect maintenance
The pipette should be regularly serviced according to the instructions for use.
The pipette performance and functioning must be checked after maintenance.
Aggressive substances can damage the pipette or pipette parts. Check for material
compatibility before using organic solvents and aggressive chemicals.
Use only original Thermo Scientifi c spare parts and ClipTip tips.
Avoid excess grease. Use only the grease provided with the pipette.
If the pipette is used daily, it is recommended to service the pipette every three months.
When the F1-ClipTip is not in use, make sure it is stored in an upright position. We
recommend a pipette stand for this purpose.
When shipping the device for service or inspection, ensure that it is completely free of
chemical, biological, or radioactive contamination.
7.1 Daily maintenance
The pipette should be checked at the beginning of each day for dust and dirt on its outside surfaces.
Particular attention should be paid to the tip cone. To clean the pipette, we recommend wiping it with
a napless cloth wetted with 70% ethanol.
Leakage test
A leakage test can be performed at any time. It is recommended to be carried out after maintenance
or autoclaving.
Pre-wet the tip three to fi ve times with water.
Aspirate a nominal volume of water into the tip.
Place the pipette on a stand or keep it fi rmly in your hand.
Wait for 20 seconds.
If a drop falls within 20 s, the pipette is leaking.
If the pipette leaks, see Chapter 9: "Troubleshooting" for possible reasons and solutions.
7.2 Periodic maintenance
The maintenance procedure starts with the disassembly of the pipette.
F1-ClipTip O-rings 5.1 are wearing parts. It is recommended to replace O-rings regularly to
ensure proper sealing. Always replace the O-rings if they are worn or damaged.
7.2.1 Disassembly of 1000ul single channel pipettes
1. Remove the tip fi tting 5 (Picture 8).
To remove the tip fi tting, place the end of tool 3 (Picture 9) without a metal rod on the tip fi tting
tool against the tip fi tting.
The tip fi tting will guide the tool properly into place. Turn the tool counterclockwise ½ turn to
untighten the tip fi tting.
Rotate the tip fi tting tool and press the end with a metal rod through the tip fi tting. Be careful not
to damage the O-ring inside the system with excess force.
Loosen the tip fi tting with a tool and pull it out. Make sure that the O-ring comes out with the tip
fi tting (Picture 10).
