6.11 Pipette calibration
Pipette calibration checks the accuracy and precision values of pipettes by weight analysis. An analytical balance is
recommended for maximum accuracy. The balance is capable of recording data from 3 to 30 samples of each
pipette tested. Each test run is stored in the application library. The number of tests which can be stored will depend
on the number of samples per test. The density table for water is included. If other liquids are used for pipette
calibration, you must enter the liquid’s density in g/cc at current room temperature. Since all calculations are made
within the balance, it is also required that you know the atmospheric pressure which has to be entered. A printout
can be made which specifies all parameters of the test made.
