Loading the rotor
Maximum loading
Overloading can result in destruction
and severe damage to the centrifuge.
The accuSpin™ can reach high rotational speeds im-
plying enormous centrifugal force. The rotors are de-
signed in a way warranting sufficient residual strength
even at the highest permissible speed.
However, this safety system presupposes that the
maximum permissible load of the rotor is not exceeded.
Please note the data about the
maximum permissible loads and
maximum speeds in chapter "Rotor
and accessories".
If you wish to centrifuge samples that together with the
adapters exceed the maximum permissible load, you
must either reduce the sample volume or calculate the
permissible speed n
perm
according to the following for-
mula:

Filling the centrifuge tubes
Check carefully whether your tubes
are approved for the respective RCF
value. Follow tube manufacturers
recommendation.
For common borosilicate glass tubes the maximum
permissible rcf is limited to 4000 xg!
The tube manufacturers normally limit the respective
maximum allowed RCF value to the fixed angle rotor.
Please note that for the same RCF value
the stress for the tubes in a swinging-
bucket rotor is higher!
