directly after the run. Rotors may be autoclaved at a maximum temperature of 121°C.

4.1.5 Disinfection of PP-rotors

Autoclaving
The recommended time for autoclaving: 15 – 20 min at 121°C (1 bar)
ATTENTION:
The sterilization time of 20 min. must not be exceeded. Repeated sterilization will
cause reduction of the mechanical resistance of the plastic material
Before autoclaving the PP-rotor and adapter must be thoroughly cleaned to avoid the burning in of dirty
residues. You can disregard the consequences of some chemical residues to plastic materials at ambient
temperatures. But at the high temperatures during autoclaving those residues may corrode and destroy the
plastic. The objects must be thoroughly rinsed with distilled water after the cleaning but before the autoclaving.
Residues of any cleaning liquids may cause fissures, whitening and stains.
Gas sterilization
Adapters, bottles and rotors may be gas sterilized with Ethylenoxyd. Make sure to air out the items after the
sterilization and before using them again.
ATTENTION:
Because the temperature may rise during the sterilization, rotors, adapters and
bottles must not be closed and must be totally unscrewed.
Chemical sterilization
Bottles, adapters and rotors may be treated with the usual liquid disinfectants.
ATTENTION:
Before applying any other cleaning or decontamination method than recommended by the
manufacturer, contact the manufacturer to ensure that it will not damage the unit or the
rotor.

4.1.6 Glass breakage

With high g-values, the rate of glass tube breakage increases. Glass splinters have to be removed immediately
from rotor, buckets, adapters and the rotor chamber itself. Fine glass splinters will scratch and therefore
damage the protective surface coating of a rotor. If glass splinters remain in the rotor chamber, fine metal dust
will build up due to air circulation. This very fine, black metal dust will significantly pollute the rotor chamber,
the rotor, the buckets and the samples.
If necessary, replace the adapters, tubes and accessories to avoid further damage. Check the rotor bores
regularly for residues and damage.
ATTENTION:
Please check the relevant specifications of the tubes centrifuges with the manufacturer.

4.1.7 Life time of rotors, buckets, accessories

Rotors and rotor lid made of aluminum or stainless steel, have an operating time of max. 7 years from first use.
Transparent rotor lids and caps made of PC or PP as well as rotors, tube racks and adapters of PP have a
maximum operating time up to 3 years from first use.
Condition for the operating time: Proper use damage-free condition, recommended care.
