Maintenance
When the Finnpipette Novus is not in use, make sure it is stored in an upright position. We
recommend a Finnpipette stand for this purpose.

Daily checking
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.

If the pipette is used daily it should be checked and lubricated every three months. The servicing
procedure starts with choosing the Service-mode from the menu (Menu -> Options -> Service).
