Pipettes should be periodically inspected to see that they are
functioning correctly, and whether they have sustained any detrimental
wear or damage. The mechanism should be tested to check that it is
working correctly and that the action of the piston is smooth and
positive.
The tip holder should be carefully examined for
marks or distortion, as it is essential for the measurement accuracy of
the pipette that the tip is a good fit on the tip holder so that no
leakage occurs. Further checks should be made with a tip fitted
and the pipette filled with liquid. Any sign of leakage could indicate
leaking seals, O-rings, or an ill fitting or inappropriate tip.
