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.

• When using smaller bag systems or in case of incompletely filled blood
bags adapters (e.g. part no. 17750) have to be inserted together with
the blood bag systems. This will avoid slipping of the bags which could
result in an imbalance.
• For the centrifugation of human blood suitable acceleration and
deceleration curves must be used. Curve no. 12 is the most suitable for
this purpose.
