Double rectangular bucket 13420 and bucket 13621
The double rectangular bucket 13420 and the bucket for microtiter plates
13621 are dynamically balances at the factory. Therefore, the buckets must
be installed in sets of 4 an in the prescribed order (see the numbers on the
buckets and on the rotor).
CAUTION
Mixed use with only two buckets on opposite sides will cause increased
imbalance!

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.

6.2.2.5
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).
• 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).
NOTE
When installing the 500 ml bottles use the supplied supporting rings
