19.2.4 Rotors and accessories with limited service lives
The use of certain rotors, hangers and accessory parts is limited by time.
These are marked with the maximum permitted number of operating cycles or with an expiration date and the
maximum permitted number of operating cycles or just with the expiration date; e.g.:
- "einsetzbar bis Ende: V. Quartal 2011 / usable until end of: V. Quarter 2011" or
"einsetzbar bis Ende Monat/Jahr: 10/2011 / usable until end of month/year: 10/2011"
- "Max. Lauf Zyklen / max. cycles: 40000".
For safety reasons, rotors, hangers and accessory parts may no longer be used if either the indicated
maximum number of operating cycles or the indicated expiration date has been reached.
19.3 Autoclaving
The rotor and accessories must not be autoclaved.
19.4 Centrifuge containers
 With leakiness or after the breakage of centrifuging containers broken container parts, glass splinters and leaked
centrifugation material are to be completely removed.
 The rubber inserts as well as the plastic sleeves of the rotors are to be replaced after a glass breakage.
Remaining glass splinters cause further glass breakage!
 If this concerns infectious material, a disinfection process is to be executed immediately.
