Adapters
In order to ensure easy handling, even if vessels of various sizes are used,
carrier systems were developed.
• Load the opposite adapters 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.

6.2.2.6
Vessels
• Load the vessels outside of the centrifuge. Liquids in the buckets or
multiple carriers cause corrosion.
• Fill the vessels carefully and arrange them according to their weight.
Imbalances result in the excessive wear of the bearings.
• Always fill the tubes up to their useful volume (= the volume that is
stated for the tube).
• After the centrifugation, remove the vessels carefully in order to prevent
the samples from mixing.
• Follow the safety instructions and hazard warnings (see chapter 3 -
Maximum speed for tubes
Some tubes, such as centrifuge glass tubes, microtubes, culture tubes,
fluoropolymer tubes and especially high-volume tubes can be used in our
rotors, buckets, and adapters at higher speeds than their breaking limit.
NOTE
When using glass vessels, the maximum value of 4,000 x g must not be
exceeded (except special high-strength glass tubes; please refer to the
information provided by the manufacturer).
