8.1.5 Glass breakage
In the case of glass breakage, immediately remove all glass particles (e.g. with a
vacuum cleaner). Replace the rubber cushions since even thorough cleaning will
not remove all glass particles.
Glass particles will damage the surface coating (e.g. anodising) of the buckets,
which will then lead to corrosion.
Glass particles in the rubber cushions of the buckets will cause glass breakage
again.
Glass particles on the pivot bearing of the load- bearing bolts prevent the buckets
and carriers from swinging evenly, which will cause an imbalance.
Glass particles in the rotor chamber will cause metal abrasion due to the strong air
circulation. This metal dust will not only pollute the rotor chamber, rotor, and
materials to be centrifuged but also damage the surfaces of the accessories, rotors,
and rotor chamber.
In order to completely remove the glass particles and metal dust from the
rotor chamber:
Grease the upper third of the rotor chamber with e.g. Vaseline.
Then, let the rotor rotate for a few minutes at a moderate speed (approx. 2000
rpm). The glass and metal particles will now collect at the greased part.
Remove the grease with the glass and metal particles with a cloth.
If necessary, repeat this procedure.

8.2 Sterilisation and disinfection of the rotor chamber and accessories
Use commercially-available disinfectants such as, for example, Sagrotan
,
Buraton
, or Terralin
.
The centrifuge and the accessories consist of various materials. A possible
incompatibility must be considered.
Before using cleaning or decontamination agents that were not recommended
by us, contact the manufacturer to ensure that such a procedure will not
damage the centrifuge.
For autoclaving, consider the continuous heat resistance of the individual
materials (see chapter 8.2.1 - "Autoclaving").
Please contact us if you have any queries (see chapter 7.3 - "Service contact").
If dangerous materials (e.g. infectious and pathogenic substances) are used, the
centrifuge and accessories must be disinfected.
