Translation of the original operating manual
Do not store any dangerous goods in the safety area of the
centrifuge.
Do not stay in the safety area longer than what is absolutely
necessary for the operation of the centrifuge.
Only use the centrifuge with rotors and accessories that have
been approved by the manufacturer. We explicitly warn against
the use of equipment of poor quality. Breaking glass or bursting
vessels can cause dangerous imbalances at high speeds.
Ensure that rotor and buckets are correctly fitted (see 6.2.2
"Installation of Rotors and Accessories“).
Observe the instructions on the installation of accessories (see
6.2.2.3).
The rotor must be loaded symmetrically at equal weights.
If liquids with a density
>
1.2 g/cm
3
are used, reduce the speed
(see 6.3.3.6 or 6.4.3.7 and 11.4.2 "Density").
Do not use the centrifuge if the rotor is loaded asymmetrically.
Do not use the centrifuge with tubes that are excessively long.
3.6.6
Resistance of Plastics
Chemical influences have a strong effect on the polymeric chains of
plastics, and therefore, on their physical properties. Plastic parts can
be damaged if solvents, acids, or alkaline solutions are used.
Refer to the resistance data (see chapter 1)!
3.6.7
Service Life of Rotors and Accessories
The rotors and accessories have a limited service life.
Perform regular checks (at least once per month) for safety
reasons!
Pay special attention to changes, such as corrosion, cracks,
material abrasion etc.
After 10 years, they must be inspected by the manufacturer.
After 50,000 cycles, the rotor must be scrapped for reasons of
safety.
If other data concerning the service life are engraved on the rotor
or bucket, these data shall apply accordingly. For example, a
bucket with the engraving “max cycles = 10,000” has a service
life of 10,000 cycles, and a rotor with the engraving “Exp.Date
02/15” must be scrapped in Feburary 2015 at the latest (see fig.
3.1)!
