Laboratory Centrifuge Maintenance and Repairs.


  • A laboratory Centrifuge is an equipment used in the laboratory, which spins liquid samples at great speeds.
  • There are many different kinds of centrifuges which largely depends on the type of samples you wish to use. It works on the principle of sedimentation.
  • Thus here the substances with different densities are separated. It is a very efficient piece of equipment and usually does not require a lot of attention in terms of repairs or fixing.
  • But like very equipment it does demand that you use it properly and make sure it is shut down properly after each use.
  • At times rotor failures do occur which can also get quite dangerous for the operator present.

Thus to reduce the risk of such unexpected failures, the manufacturers recommend periodic maintenance of the equipment and have proper procedures laid out for that.

Laboratory Centrifuge Maintenance:


  • Ideally the initial calibration of a centrifuge should be performed by a qualified service technician.
  • In an ideal world it would be best if maintenance procedures were carried out on a daily basis, monthly basis as well as annually.

Here is a brief guide as one could go about performing such maintenance routines.

Daily Maintenance:


  • It is a good practice to wipe the inside of the bowl with a disinfectant solution and rinse it thoroughly.
  • The operator should be alert enough to never use the centrifuge device if it is hot, or if unusual vibrations or noises occur, or if deterioration (of parts) is detected. In such a case it would be advisable to contact a qualified service technician.

Monthly Maintenance:


  • As a monthly routine maintaining your laboratory centrifuge you should clean the centrifuge housing, rotor chamber, rotors and rotor accessories with a neutral cleaning agent. The centrifuge and the accessories should be cleaned with soap water or a mild cleaning agent with a pH value ranging from 6 to 8.
  • In addition to which you should also clean plastic and non-metal parts with a fresh solution.

Annual Maintenance:


  • It is necessary to get the centrifuge serviced by a qualified service technician who must ensure that the unit is operating safely and properly. It is usually best to contact the manufacturer or the supplier in order to get hold of a technician.
  • The service should include cleaning condenser coils, fans screens and filter.
  • It should also include checking the centrifuge brushes, bearings, timer, temperature and speed as well as the electrical integrity.
  • Ideally the service technician must issue an inspection certificate indicating compliance with safety and proper operations.

General Tips on Maintaining Laboratory Centrifuge:


  • The responsibility of regular maintenance of the laboratory centrifuge usually likes on the shoulders of the laboratory technician or operator. It is a good idea to set a reminders either on your phone or computer calendar so that you don’t forget these important dates.

Here are a few important tips:

  • If during the operation of the centrifuge any liquids from the tube sample spills on the centrifuge device itself then this should be taken care of immediately.
  • Thus to avoid an chances of corrosion or damage such spills should immediately wiped off.
  • In addition to which it should also be allowed to dry thoroughly.
  • Optionally you can also oil the aluminium rotors and buckets though make sure it is dry first.
  • Since a damaged or cracked sample tube can easily deteriorate inside the centrifuge while in use and cause a lot of damage. And the most important of all, make sure you replace or repair any damage parts.
  • So the next time you come across someone asking as to what is equipment maintenance you will surely be in a good position to spurt out a quick answer.
