Routine Evaluation and Care of Your Rotor

Each time you use a rotor, visually inspect its condition for signs of physical wear or damage:
• Corrosion in the rotor cavities or exterior surfaces.
• Scratches or gouges to the base metal.
• Missing or worn anodizing.
• Damage to contact points, such as thread, hubs and screws.
Over time, stress observed in a typical fixed angle rotor will cause metal fatigue.
Heavy corrosion can result in premature rotor failure.
Routine Evaluation and Care of Your Rotor
Rotors are frequently damaged in use and this damage may be exacerbated under centrifugal forces. As
a result, even a tiny flaw in a critical part of the rotor may generate stresses greater than the rotor was
designed to withstand. Rotors are also subject to high levels of stress due to the centrifugal force created
by high rotational speeds, and repeated cycles can cause metal rotors to stretch and change in size.
Proper Handling
Improper installation can lead to failure so it is imperative to:
• Always make sure that the rotors are fixed with the Autolock.
• Ensure buckets are properly seated on their trunnions.
• Avoid dropping or striking the rotor against a hard surface.
• Avoid putting anything inside the rotor that could scratch or nick the surface.
In addition, ensure that all tubes, bottles and adapters are being used within their specified limits and
according to the manufacturer's directions. Tube or bottle failures during centrifugation can result in
minor to severe damage to rotors and centrifuges.
