Loading the rotor

Standard centrifuge containers of glass will not stand RCF values exceeding 4000 (DIN 58970, pg. 2).
•
Check the rotor for firm seating.
With swing-out rotors all rotor positions must be lined with identical hangers. Certain hangers are marked with
the number of the rotor position. These hangers may only be used in the respective rotor position. Hangers that
are marked with a set number (e.g. S001/4) may only be used in the set.
•
The rotors and hangers may only be loaded symmetrically. The centrifuge containers have to be distributed
evenly on all rotor positions. For authorised combinations see Chapter "Anhang/Appendix, Rotoren und
Zubehör/Rotors and accessories".
In the case of angle rotors all possible rotor positions must be loaded, see chapter "Anhang/Appendix, Rotoren
und Zubehör/Rotors and accessories".
Rotor is evenly loaded
•
On certain hangers, the weight of the maximum load or the weight of the maximum load and the maximum
weight of the completely loaded hanger is specified. This weight may not be exceeded. In case of exception, see
chapter " Centrifugation of materials or mixtures of materials with a density higher than 1.2 kg/dm
specified for the maximum loading includes the total weight of adapter, frame, centrifuging container and content.
•
In containers with rubber inserts, the same number of rubber inserts must always be among the centrifuge
containers.
•
Always fill the centrifuge containers outside of the centrifuge.
•
No liquid should be allowed to enter the centrifugal chamber during filling and swinging out of the hangers.
•
The maximum filling quantity for the centrifuge containers specified by the manufacturer must not be exceeded.
•
In order to maintain the weight differences within the centrifuge container as marginal as possible, a consistent
fill level in the containers is to be heeded.

Aerosol tight sealing of angle rotors

To ensure aerosol sealing the lid of an aerosol sealed angular rotor must be firmly closed.
This is performed with the help of the supplied spanner that is inserted through the borehole
in the rotary handle. If the rotary handle does not have a borehole then the lid must be firmly
closed by turning in clockwise direction.
For available aerosol tight angle rotors, please see chapter "Anhang/Appendix, Rotoren und
Zubehör/Rotors and accessories".
