In case of rotors designed with the cover they must not be used without it. Rotor covers must be
closed exactly. Rotor covers ensure smaller drags of the rotors, proper setting of the test-tubes
and airtight sealing.
One should use only buckets intended for selected types of the rotor.
Fill test tubes outside the centrifuge.
In case of centrifuging in an angle rotor, test tubes (buckets) have to be filled properly in order to
prevent from pouring fluids during centrifuging.
Tubes must be filled so that the material does not escape
from the reservoir during centrifugation.
One shall fill tubes according to formula:
Max liquid level < Tube height – Internal tube diameter/2
Observe the manufacturer's restrictions about the filling of the test tube.
It is recommended to equalize vessels loads, as much as possible in order to ensure
minimal vibrations during operation.
