Rotor Removal and Installation:
To remove the rotor:
1. Unlock the centrifuge by pushing the ‘OPEN / EMERGENCY STOP’ button and unlatch and
open the lid.
CAUTION:
1) Unplug the centrifuge from the electrical outlet at this time to eliminate the possibility of electrical
shock or other injury.
2) Rotors may be removed for cleaning. However, rotors are not to be replaced in the field. The
factory installed rotor is the only rotor intended to be used in the centrifuge.
2. Remove the test tube holders.
3. Remove the screw in the center of the rotor using the supplied 5/32” Allen wrench by turning
the screw counterclockwise. Be sure to save the screw and washer in a safe place.
4. The rotor is sitting on a cone-shaped adapter. Pull the rotor up and off of this adapter.
5. Remove the rotor from the rotor chamber.
NOTE: If you are removing the performance plus rotor, you must: 1) Move the rotor towards
the front of the centrifuge; 2) Angle the back edge of the rotor; 3) Slide it through the
opening. See illustration below.
To install the rotor:
1. Place the rotor back onto the cone-shaped adapter. You may need to turn the rotor slightly to
line it up properly.
NOTE: If you are installing the performance plus rotor, angle the rotor as needed to get it back
into the rotor chamber.
2. The rotor should slide onto the rotor cone freely.
3. Once a proper fit has been achieved, thread the screw and washer back into the center of the
rotor. Use the Allen wrench to tighten the screw.
4. Replace the tube holders and verify that they are seated properly.
5. It is recommended that the initial setup procedures be performed to ensure that the rotor has
been installed correctly and that no damage has been done to the centrifuge during either the
rotor installation or possible rotor chamber cleaning.
