The centrifuge also should be observed to verify proper appearance of screws, lid hooks, latches and for
evidence of corrosion.
In case of problems contact your Thermo Service representative, because any deviation from the
above mentioned advice may have serious consequences for the safety of the appliance and of the
operators.
Normal use of the centrifuge could require the manipulation of biohazards. Users and service
personnel must have specific training for each substance they use, according to the “Laboratory
Biosafety Manual” from the World Health Organization.
4.7. Sample Loading
The contents of each rotor pocket including sample, tube, cap and adapter (where used) must be of the
same weight as the one diametrically opposite.
Imbalance of the rotor may cause major damage to the rotor and centrifuge.
Do not attempt to introduce liquids into rotor pockets or into tubes already in the pockets.
Distribute the load correctly. Loads should be inserted two by two, samples of equal weight, at 180 degrees
from the rotation axis and at equal distance (radius) from the center of rotation (see pictures)
When using fixed angle rotor, weight deviation between the tubes must not exceed ±5 grams.

Instructions for Use
17
When using a swing-out rotor, the samples are placed in plastic inserts. The load must be statically and
dynamically balanced:
-
Static balancing
consists of balancing the weight of the 2 inserts which are in opposite locations in the
rotor (±8 to 10 grams).
-
Dynamic balancing
consists of placing the tubes in each insert symmetrically according to the axis of the
trunnions.
