11.7 Service life for accessories
The following requirements must be met in order to use rotors, rotor lids and accessories:
•Proper use
• Recommended maintenance
• Undamaged condition
The service life of rotors and accessories is indicated by two values:
• Service life in years from initial setup
• Maximum number of cycles
The decisive factor for the service life is which case occurs first, usually this is the number of years in
operation.
A cycle is a centrifugation run during which a rotor accelerates and is braked. The speed and the duration
of the centrifugation run do not matter.
For the other rotors and rotor lids of this centrifuge there is no limit for the service life.
The date of manufacture is stamped on the rotors in the format 03/10 (= March 2010) or on the inside of the
plastic rotor lids and caps in the form of a clock . This is for information only and does not have any
reference to the service life.
CAUTION! Danger due to material fatigue.
If the service life is exceeded, it cannot be guaranteed that the material of the rotors and the
accessories will withstand the stresses during centrifugation.
 Do not use any accessories which have exceeded their maximum service life.
