6.2.2.4 Adapters
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.

6.2.2.5 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-strength glass tubes; please refer to the
information provided by the manufacturer).
• Follow the safety instructions and hazard warnings (see chapter 3 -
"
Safety
")!

6.2.2.6
Blood bag systems
The centrifuge tolerates an imbalance of approx. 20 g. Therefore, it is
important to balance the buckets carefully.
• All four places of a rotor must be loaded with buckets. It is permissible
to fill just two opposite buckets with blood bag systems.
• The opposite buckets including the filled blood bag systems must have
an equal weight.
• The blood bags have to be put into the opposite buckets mirror-inverted.
• If in one bucket the main blood bag is on the left side, then the main
blood bag inserted in the opposite bucket has to be on the right side.
