5.1.4 Disinfection of aluminum rotors
In case of infectious material spilling into the centrifuge, the rotor and rotor chamber have to be disinfected directly
after the run. Rotors may be autoclaved at a maximum temperature of 121°C.
5.1.5 Disinfection of PP-rotors
Autoclaving
During autoclaving, it´s quite possible that plastic parts, e.g., rotor, can become deformed!
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.
5.1.6 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.
Lifetime 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.
