Removing the rotor
The removal of the rotor is performed in reverse order. When loosening the
rotor with the aid of the rotor wrench, it may be necessary to overcome a
certain resistance. Do not apply the hexagon key until the rotor has been
loosened with the rotor wrench to such an extent that the rotor hub turns
together with the rotor and the "two-finger-principle" can be applied.

Installation of accessories
• Only use vessels that are suitable for the rotor.
• In the case of swing-out rotors, all of the compartments must be
equipped with buckets.
• Always load rotationally symmetrical compartments of the rotors with
the same accessories and fill to avoid imbalance.
Centrifugation with vessels of various sizes
Working with vessel of various sizes is possible. In this case, however, it is
very important that the rotationally symmetrical inserts are identical.

Centrifugation with low capacity
• Install the sample vessels in a rotationally symmetrical manner so that
the buckets and their suspensions are loaded evenly.
• It is not permissible to load angle rotors on only one axis.
