3.2 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.
3.3 Removing and installing the angle rotor
The Corning
LSE
High Speed Microcentrifuge comes complete with a standard 24
place rotor installed. To remove the rotor for cleaning, remove the rotor securing
screw from the motor shaft by turning the screw counterclockwise, using the rotor
wrench. Lift the rotor directly upward in a straight vertical motion.
To replace rotor, first make sure the motor shaft and rotor mounting hole are clean.
Place the rotor on the motor shaft. Reinstall the rotor securing screw on the motor
shaft by turning it clockwise. Hold the rotor with one hand and
tighten the rotor
securing screw, using the rotor wrench.
Figure 1. Loading the rotor to achieve balance
3.4 Loading the rotor
Tubes to be loaded should be filled equally by eye. The difference in the weight
between the tubes should not exceed 0.1 gram. Tubes should always be loaded so that
there is equal spacing between all tubes. One or two additional loaded tubes may need
to be added to achieve this. Refer to Figure 1. to see one typical balancing scheme.
