TROUBLE SHOOTING

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.

3.1.6 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 severely 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 residue and damage.

ATTENTION: Please check the relevant specifications of the tubes centrifuges with the

manufacturer!

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:

Proper use, damage-free condition, recommended care.

For additional information on aerosol-tight rotors, lids and buckets, please see below:

The aerosol tightness of rotors, rotor lids, buckets and caps have been tested and certified by the

"TÜV Nord CERT GmbH, Certification Body Consumer Products, Essen (Germany)", in accordance

with Annex AA of IEC 61010-2-020. The certificates can be downloaded on our webpage,

www.hermle-labortechnik.de. Aerosol-tight rotors and buckets are marked with the label, "aerosol-

tight".

ATTENTION: Autoclaving, mechanical stresses and contamination, by chemicals or other

aggressive solvents, can impair the aerosol-tightness of the rotors and buckets.
