6. 2. Sterilization of Rotor

Sterilize the rotor appropriately following Table 6-1.
Do not autoclave the rotor or sterilize it in boiling water because its material may deteriorate and its strength may decrease.

6. 3. Inspection of Rotors

Check the rotor as follows after every use.
• If the optical adapter/disk is unclean, wipe it with a soft cloth but do not damage it.
• Replacements of packings and O-rings are available.
• If the rotor appears to be corroded, deformation, cracks or discoloration is observed, do not use the rotor and call
a Thermo Fisher Scientific authorized sales representative. The rotor may be irreparable depending on the degree
of corrosion and wear.
