7.0 Rotors and Rotor Maintenance

7.1 Rotors and accessories

The following accessories are available for the Spectrafuge 16M Microcentrifuge.
Angle rotor for 18 x 1.5 mL tubes
Adapter for 0.5 mL tubes
Adapter for 0.4 mL tubes
Adapter for 0.2 mL tubes

7.2 Rotor maintenance

The rotor should be cleaned thoroughly after each use. Thorough cleaning must be performed when spinning samples containing
phenol or phenol chloroform. Periodically inspect the rotor for dents, dings, scratches, discoloration and cracks. If any damage to the
rotor is found, discontinue use of the rotor immediately and replace.

7.3 Mounting and securing the angle rotor

Remove the rotor screw from the motor shaft by turning the screw counterclockwise. Clean the motor shaft and the rotor mounting hole
(see Figures 1 and 2). Place the rotor on the motor shaft ensuring that the cross-pin (Figure 1) aligns correctly with the rotor slot (Figure 2).
NOTE: Reinstall the rotor screw on the motor shaft by turning it clockwise. Hold the rotor with one hand and hand-tighten the rotor
screw. Use an adjustable or 1/4 inch wrench to tighten the screw When loading the rotor, refer to Figure 3. Loading in the pattern
indicated will ensure a balanced load. Tubes to be loaded should be filled equally and the difference in the weight between the tubes
should not exceed 0.1 gram. The difference in the weight between the tubes should not exceed 0.1 gram. A partially loaded rotor may
be centrifuged if the loading scheme for balancing a rotor given in Figure 3 is followed.

7.4 Removing the rotor

Using an adjustable or 1/4 inch wrench to loosen the screw, and remove the rotor retaining the screw/washer assembly by turning it
counterclockwise. Lift the rotor directly upward in a straight vertical motion.
CAUTION: Be sure to secure the rotor screw and tighten with a wrench before further operation.
