The rotors expand and contract every time they are spun up and stopped, causing unavoidable metal
fatigue that limits their usable cycles. Therefore, usable number of cycles are provided as guide for
timely replacement of rotors.
To ensure safe operation, use of rotors beyond the usable number of cycles may lead to breakage of
the rotors.
[Usable number of cycles for rotors]
When the used number of cycles has reached to the table below, the rotors are considered to expire
the life.
Earlier replacement of the rotor may be necessary if any corrosion is present, or if lowered strength,
scratch or deformation due to misuse occurs.
In such cases, please contact your nearest dealer and have the rotor checked before using them
again.

However, such parts may deteriorate over time after repeated use.
We recommend replacement of resin parts when the rotor is replaced.
Usable Number of Cycles for Rotors
WARNING
Use of rotors beyond the usable number of cycles may lead to breakage of the rotor.
If the rotor is used continuously even after the usable number of cycles of rotors has
expired, should the rotor get damaged, the main unit of the centrifuge suddenly may
start to rotate; this could result in an accident causing injury or death.
