Disinfection Of Aluminum Rotors; Glass Breakage; Lifetime Of Rotors And Accessories - Hermle Z 287 A Operating Manual

MAINTENANCE
Gas Sterilization
Adapters, bottles and rotors may be gas sterilized, with Ethylenoxyd. According to the duration of the
application, allow items to properly air out, after the sterilization and before usage.
ATTENTION: The temperature may rise during the sterilization; rotors, adapters and bottles
should not be fully closed, keep completely unscrewed.
Chemical Sterilization
Bottles, adapters and rotors may be treated, with the usual liquid disinfectants.
ATTENTION: Before applying any other, Cleaning Resp. Decontamination Method, other than
what was recommended by the manufacturer, contact the manufacturer to ensure that it will
not damage the unit or the rotor.

3.1.5 Disinfection of Aluminum Rotors

In case of infectious material spilling into the centrifuge, the rotor and rotor chamber have to be
disinfected, promptly after the run. Rotors may be autoclaved, at a maximum temperature of
121°C/250°F.

3.1.6 Glass Breakage

With high g-values, the rate of glass tube breakage increases. Glass splinters have to be removed
immediately from rotor, 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
severely pollute the rotor chamber, the rotor and the samples.
If necessary, replace the adapters, tubes and accessories, to avoid further damage. Check the rotor
bores regularly, for residue and damage.
ATTENTION: Please check the relevant specifications of the tubes centrifuges with the
manufacturer!

3.2 Lifetime of Rotors and Accessories

Rotors and rotor lid made of aluminum or stainless steel, have a 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 of up to 3 years, from first time use.
Conditions for the Operating Time:
