5.2.4.1 Carrier Systems
In order to ensure easy handling, even if vessels of various sizes are used,
carrier systems were developed.
• Load the opposite carriers with the same number of vessels and with the
same weights in order to avoid imbalance.
• If all of the compartments of a carrier are not used, the buckets must be
loaded evenly. Loading the edges of a bucket only is not permissible.
5.2.4.2 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 14!
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 10 years, they must be inspected by the manufacturer.
• After 50,000 cycles, the rotor must be scrapped for reasons of safety.
