5.2.4.1 Tubes
•
Load the tubes outside of the centrifuge. Liquids in the buckets or multiple
carriers cause corrosion.
•
Fill the tubes carefully and arrange them according to their weight.
Imbalances result in the excessive wear of the bearings.
•
In high-speed angle rotors, the vessels must be filled up to their useful
volume (= the volume stated for the vessel). If the vessels are only partially
filled, they will deform. This may result in leaks at the seals that may become
loose.
•
When using glass tubes, the maximum value of 4,000 x g must not be
exceeded (except special high-strengh glass tubes; please refer to the
information provided by the manufacturer).
)
Attention!
•
Please observe the instructions on safety and hazards in chapter 2,
page 16!
5.2.5 Service Life of Rotors and Accessories
The rotors and accessories have a limited service life.
•
Please perform regular checks (at least once per month) for safety reasons!
•
Pay special attention to changes, such as corrosion, cracks, material
abrasion etc.
•
After 7 years, the rotors must be inspected by the manufacturer.
•
After 50,000 cycles, the rotor must be scrapped for reasons of safety.
•
Replace all polypropylene rotors (order no. 12124, 12126, 12101) after
autoclaving 20 times or 5 years.
•
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. 5.9)!
