Operation
Centrifuge 5424/5424 R

5.4.2 Inserting the rotor
1. Fit the rotor vertically on the motor shaft.
2. Insert the supplied rotor key into the rotor nut.
3. Turn rotor key clockwise until the rotor nut is firmly tightened.
5.4.3 Loading the rotor
To load the rotor, proceed as follows:
1. Check the maximum load (adapter, tube and contents) per rotor bore.
The information about this can be found on every rotor and in this operating manual (see Rotors on
p. 18).
2. Load rotors and adapters only with the tubes intended for them.
3. Insert tubes opposite each other in pairs into the rotor bores. For symmetric loading, tubes that face
each other must be the same type and have the same filling quantity.
CAUTION! Risk of injury due to asymmetric loading of a rotor.
Load rotors symmetrically with identical tubes.
Only load adapters with suitable tubes.
Always use the same type of tubes (weight, material/density and volume).
Check symmetric loading by balancing the adapters and tubes used with scales.
CAUTION! Risk from damaged or overloaded tubes.
When loading the rotor, observe the safety precautions on dangers as a result of
overloaded or damaged tubes (see Warnings for intended use on p. 9).
Rotor lid
• Fixed-angle rotors may only be operated with the appropriate rotor lid in each case. This is
clearly shown by the identical rotor name labeling on the rotor and on the rotor lid.
• To carry out an aerosol-tight centrifugation, the aerosol-tight rotor (marked: Red ring) and
the corresponding aerosol-tight rotor lid (marked: Aerosol-tight and Red lid screw) must
be inserted.
