Operation
Rotor management
Thermo Scientific WX Ultra Series 2-61
To utilize this feature, each time a rotor is used it must be recorded by the ultracentrifuge. To do this, a
rotor must be initially registered in the Rotor Management software. Each time the rotor is used in the
Sorvall WX Ultra series ultracentrifuge, it must be selected from the Rotor Management Screen prior
to starting the run. Additionally, should the rotor be used in other ultracentrifuges, the Rotor
Management information can be edited to record this usage. Rotors may also be deleted from the Rotor
Management Screen if they are no longer to be used.
If you use the rotor beyond its maximum permitted life, a serious accident may occur. (For more
information, see rotor instruction manual.)
Automatic rotor deration
You can register a rotor in the ultracentrifuge before use. After the rotor has been registered, you can
utilize the rotor management feature of the ultracentrifuge each time a run is made using the rotor.
When the registered rotor comes close to the end of its life, the ultracentrifuge indicates it by displaying
a message on the screen. When the rotor reaches its primary life, the ultracentrifuge derates its
maximum permitted speed and inserts [] at the right side of the rotor S/N. Once the maximum
permitted speed is derated, the actual speed of the rotor is automatically restricted within the new
limits.
Automatic rotor exclusion
When a registered rotor reaches the end of its life, the ultracentrifuge indicates it by displaying a
message on the screen. Subsequent runs of this registered rotor are precluded.
Registering a rotor
A standard rotor can be registered when you use the rotor management feature of the ultracentrifuge. If
the rotor has not been registered, the feature does not operate for the rotor. To register a rotor, use the
procedure described below.
As an example, suppose that you need to register a fixed angle rotor with the
following data, and that it has been used with an ultracentrifuge of a different
model from the one mentioned below:
Model: T-890 Serial number: 9910876
Total number of runs thus far made: 500
Total number of hours thus far spent in the runs: 1200 hours, 24 minutes
Note The rotor life management data stored in the ultracentrifuge is not covered by the warranty.
When a rotor is used with the ultracentrifuge, be sure to record the rotor management data in the
rotor log book. (You can also paste a printout in the log book.) If the rotor log book is not
maintained correctly, the rotor will not be warranted.
