MAINTENANCE

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.

Check the integrity of the seals of the aerosol-tight rotor lids or caps, before each use.

Use only aerosol-tight rotor lids or caps, if the seals are undamaged and clean.

Aerosol-tight plastic rotors as well as plastic lids and seals of aerosol-tight aluminum rotors and

buckets must be replaced after 10 autoclaving cycles.

Never store aerosol-tight rotors or buckets closed.

Plastic lids and seals of aerosol-tight aluminum rotors and aluminum buckets must be replaced after ten

autoclaving cycles.
