7. Functional check
7.1. Functional check at factory
Following assessories are required to perform the functional check:
− Testing rotor
− Two reaction receptacles filled with water
Table 7 lists measured values, and, ranges of measured values, which have been laid
down for these assessories.
In the final check, the functional efficiency of each centrifuge is verified, with the meas-
ured values and ranges of measured values being taken into account.
