To remove or to close the rotor lid press both locking bolts together.
3.4 Overloading of rotor
The max. load permitted for a rotor, which is determined by the manufacturer, as
well as the max. speed allowed with the rotor (see indications on the rotor itself)
must not be exceeded.
The liquids with which the rotors are loaded should have an average homogeneous
density of 1,2 g per ml or less, when the rotor is running at maximum speed.
To spin liquids of a higher density, the speed should be reduced according to the
following formula:

3.5 Removing of the rotor
Take off the rotor lid and hold the rotor with one hand. Turn the rotor nut clockwise,
until the rotor is loose and take the rotor vertically off the shaft.
