6.2.2.2 Installation of accessories
• Only use inserts that are suitable for the rotor.
• All buckets of the swing-out rotor need to be installed when spinning.
• Always load the axial symmetrical inserts/buckets of the rotors with the
same accessories and fill to avoid imbalance.
Centrifugation with different tube sizes
Working with different tube sizes is possible. In this case, however, it is
very important that axial symmetrical inserts are identical (see figure).

Centrifugation with low capacity
• Install the tubes axial symmetrically so that the buckets and their inserts
are loaded evenly.
• It is not permissible to load angle rotors on only one axis.
