Cycle Counter
The lifetime of rotors and buckets is dependent on the amount of mechanical load. Do not exceed the
number of cycles recommended for rotors and buckets.
The maximum number of cycles is given in the rotor table in the rotor specification section.
The maximum number of cycles for buckets is marked on the buckets themselves.
The rotor can run at high speeds. The rotor design has sufficient reserve stability even when spinning at
top speed.
The safety system of the centrifuge requires that you do not overload the rotor.
There are two options available for centrifuging samples whose weight, including adapt
e
r, exceeds the
maximum permissible load:
Reduce the fill level.
Recalculate the maximum permissible speed according to the following formula and select the
calculated maximum speed for the centrifuge:
WARNING
Replace the rotor when the specified number of cycles is reached. Due to the
mechanical load a rotor can break and thus damage the centrifuge.
Replace the buckets when the specified number of cycles is reached.
