Loading the rotor

Standard centrifuge containers of glass will not stand RCF values exceeding 4000 (DIN 58970, pg. 2).
• Check the rotor for firm seating.
• The rotors must be loaded symmetrically. The centrifuge containers have to be distributed evenly on all rotor
positions. For authorised combinations see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and
accessories".
Example:
Rotor is evenly loaded
• The centrifuge containers may only be filled outside of the centrifuge.
• The maximum filling quantity for the centrifuge containers specified by the manufacturer must not be exceeded.
The centrifuging vessels may only be filled so
far that no fluid can be expelled from them
while the centrifuge is running.
• When loading the rotor, no liquid may enter the rotor or the centrifuging chamber.
• In order to maintain the weight differences within the centrifuge container as marginal as possible, a consistent
fill level in the containers is to be heeded.
• The weight of the permissible filling quantity is specified on each rotor. This weight may not be exceeded.
Installation:
• Clean the motor shaft (A) and the bore of the rotor and then apply a
thin coat of grease to the motor shaft. Dirt particles between the
motor shaft and rotor prevent the rotor from having a perfect seat and
cause it to run unsteadily.
• Place the rotor vertically onto the motor shaft. When putting on the
rotor, the marking beam (B) on the rotor must be parallel to both
surfaces (C) on the motor shaft.
• Tighten the clamping nut of the rotor with the Allen wrench (included
in delivery) by turning clockwise.
• Check the rotor to make sure it is seated firmly.
C
Removal:
• Loosen the rotor's clamping nut by turning counter-clockwise with the
Allen wrench (included in delivery) and turn up to the lifting pressure
point. After overcoming the lifting pressure point, the rotor is released
from the cone of the motor shaft. Turn the clamping nut until the rotor
can be lifted up from the motor shaft.
• Lift up the rotor from the motor shaft.
