11.1.6 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 extremely pollute the rotor chamber, the rotor, the buckets and the samples.
If necessary, replace the adapters, tubes and accessories to avoid further damages. Check the rotor
bores regulary for residues and damages.
Attention: Please check the relevant specifications of the tubes centrifuges with the
manufacturer!
