Sample Loading

4-6 T3/G3
Before installation, the rotor should be thoroughly inspected for
evidence of corrosion or other damage and for cleanliness.
Chemical and stress corrosion of metallic parts will eventually lead to
disruption of the rotor with potential severe damage to the centrifuge.
Particles stuck inside the pockets can cause breakage of tubes and lead
to major imbalance and / or loss of sample and contamination.
The central hole of the rotor and the drive spindle should also be clean
and undamaged. These parts should be wiped clean before each use.
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. L
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. L
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. L
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.
