Stress Corrosion
Stress distribution is an important consideration when evaluating the extent of rotor damage.
Ultraspeed rotors experience the highest level of stress of all rotors; if it is run above its rated speed, it
probably has exceeded its yield point. In this event, the metal is permanently deformed and rotor life is
severely compromised. Lower speed metal rotors will also become fatigued, depending on the rotor
type, number of runs and the speed of those runs. However, corrosion, improper handling and misuse
will often require that you retire your rotor long before normal fatigue becomes a danger.
Missing Paint and Anodization
While missing paint will not affect the life of a titanium or carbon fiber rotor, missing anodization
onan aluminum rotor may signal that it is time to retire the rotor.
Dropped Rotors
Deformation caused by dropping a metal rotor cannot be repaired, requiring that the rotor be replaced.
In some cases, carbon fiber rotors are repairable if damaged
. T
he test is carried out by TFS.
Overheating
Melted bottles or other plastic or a rotor that is too hot to touch are indications that a rotor has
overheated. Aluminum and carbon fiber rotors can be autoclaved up to 121
°C, while titanium
and stainless steel rotors can withstand higher temperatures and are not likely to be damaged by
heat generated in the centrifuge.
Rotor Maintenance
Protect your rotor against damage or failure with preventive measures and maintain maximum
centrifuge performance. However, if rotor damage is observed, ensure the safety of your lab by taking
recommended action or contacting your sales representative for an inspection.
Potential Damage
Preventive Measures
Recommended Action
Damage to lid assembly
•
Lubricate periodically with a light film of o-
ring or vacuum grease.
•
Keep lid assembly lubricated with anti-
galling grease
•
Avoid banging or dropping
•
Use care when removing o-rings.
•
Clean with non-abrasive cloth and mild
detergent.
Return lid assembly parts to
manufacturer for repair or
replacement.
Damage to biocontainment
sealing lid
•
Use care when removing o-rings.
•
Inspect and replace o-rings regularly.
Replace sealing lid to ensure
proper containment
