3.1.5 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!

Rotor and adapter have an operating time of max. 3 years from first use.

Conditions for the Operating Time:

Proper use, damage-free condition, recommended care.
