Standard deviation can be expressed as a relative value (CV) CV = 100% x S / V
When the Finnpipette FOCUS is not in use, make sure it is stored in an upright position. We
recommend a Finnpipette stand for this purpose.

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.
Short-term service
If the pipette is used daily it should be checked and lubricated every three months.
