Precautions on Handling rotor
Do not spin a rotor beyond the allowable speed.
The maximum speed marked on a rotor refers to an allowable one when the maximum density
of the sample or density gradient solution is less than 1.2.
When a sample or density gradient solution of more than 1.2 in maximum density is used, the
maximum speed must be reduced according to the instruction manual for the rotor.
Upon reaching the end of the service life of a rotor specified in its instruction manual, the
allowable speed should be reduced by 10%.
Set a rotor gently and securely onto the drive shaft hub.
Practice setting repeatedly to acquire the knack.
Confirm that the rotor is free from corrosion and scores.
If white corrosion is recognized on a tube hole bottom of an angle rotor, or a hole bottom of a
bucket for swing rotor, immediately stop using it and contact the nearest agent of Thermo
Scientific.
When operation is over, store the rotor after cleaning and drying.
Make it a practice to keep a logbook for rotors.
Keeping a logbook for rotors is indispensable for controlling the life or when the warranty
clause is involved. Keep the logbook up to date and store it properly.
