Maintenance and Care
2. 1. Rotor and Components Inspection
CAUTION Do not run any rotor or components with sign of damage.
Ensure that the rotor, buckets and components are within the service life and number of cycles.
It is recommend that you have rotors and components inspected yearly as part of your routine service to
ensure safety.
After thoroughly cleaning the rotors, they must be inspected for damage, wear and corrosion.
The cycle limits of the rotors are stated in the technical data section of each rotor. [
à 2
B–1]
NOTICE
Usage beyond these limits might lead to rotor failure, sample loss and damage to the centrifuge.
The cycle limits of the buckets are stated on the buckets themselves and stated in the technical data section of each rotor.
[ à 2 B–1]
NOTICE Usage beyond these limits might lead to rotor failure, sample loss and damage to the centrifuge.
Metal Parts
Ensure that the protective coating is complete. It can be removed through wear and chemical attack and can lead to unseen
corrosions. In case of corrosion, such as rust or white / metallic pitting, the rotor or components must be removed from service
immediately. Particular attention should be paid to the bottom of buckets on swing out rotors and tube cavities on fixed angle
rotors.
Plastic Parts
Check for signs of plastic crazing, fading, bruising or cracking. In case of damage, the inspected item must be removed from
service immediately.
Cycles of Rotors and Buckets
The centrifuge counts cycles for a rotor type. The centrifuge does not count the cycles of the buckets. You have to count the
cycles of the buckets using your own method. The centrifuge can not detect the change or replacement of rotors of the same
type or buckets.
The service lifetime of a rotor and its buckets depends on the amount of physical load. Do not use rotors and buckets that exceed
the maximum number of cycles.
The maximum number of cycles for rotors is given in the Rotors chapter. [ à 2 B–1]
The maximum number of cycles for buckets is marked on the buckets themselves.
You can check the number of cycles for a rotor type on the user interface of the centrifuge. The rotor log saves the information of
the used rotors and buckets. Press Settings (gears symbol), then Runs and then Rotor Log to see the information. Besides the
values of the rotor an information about the number of cycles completed by this rotor type in this centrifuge is shown.
For detailed instructions and information refer to the separate manual for the Thermo Scientific Centri-Touch User Interface.
