1. 3. Precautions
•
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 Fisher 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.
•
Do not rotate this rotor at a speed of more than 5000 rpm unless all components (rotor assembly, cap assembly)
are assembled.
Do not rotate this rotor at a speed of more than 5000 rpm unless the rotor is filled with liquid.
If the above cautions are not observed, septa could be damaged.
•
Always ground the ultracentrifuge before use.
