Topic: Preventative Maintenance

It is important to regularly clean, inspect and lubricate the rotor and accessories in all Hettich centrifuges. General maintenance procedures will ensure proper operations, provide optimal and consistent results plus extend the life span of all components. Regular inspection and lubrication can reduce the operational noise, decrease potential vibrations and prevent imbalance errors from occurring.

For optimal results, Hettich suggests following the attached Preventative Maintenance Schedule.

To clean, inspect and lubricate a Hettich Centrifuge, please follow these steps:

  1. Remove all accessories (inserts, adapters, buckets) and rotor from the centrifuge. For instructions on how to remove the rotor, please click here.
  2. Inspect all items for wear and tear, especially the contact areas of the swing out buckets and the rotors.
  3. The contact points must remain lubricated using Hettich grease (Cat. No. 4051) at all times to ensure they achieve their designated position. These points are also under great stress and should be examined periodically for signs of wear. Contact our This email address is being protected from spambots.

  4. Lubricate lightly using the Hettich grease at all metal to metal contact points between the bucket and rotor, and the rotor and centrifuge. Lubrication is indicated when the metal to metal contact squeak, or a bucket doesn't swing freely when moved out of the vertical position at standstill. See the Product Manual for proper operation of a centrifuge.
  5. If too much grease is applied, a small ring of grease will spin off onto the chamber wall of the centrifuge. This cleans up easily with a soft cloth and does not harm the centrifuge.
  6. Replace the rotor and tighten securely using the enclosed 5mm allen wrench. Lift up on one side of the rotor to ensure a snug fit. Replace the buckets and accessories. For instructions on how to properly replace the rotor, click here.
  7. Clean the buckets, inserts and rotors with a mild, non-aggressive cleaner. Remove anything that might add unwanted weight inside the bucket or insert. Certain parts and accessories can be autoclaved.
