10 tips to use Doctor’s centrifuges safely

Doctor's centrifuges

Doctor Centrifuge is a very common laboratory equipment, in addition to which it is also a vital piece of research equipment. This device operates at a very high speed, and it is for this reason that it is effective in separating the material based on density. This same high speed can also be a hazard at times, resulting in aerosol creation to equipment instability and failure. In case the centrifuge tube breaks inside the rotor, Aerosols is created inside the centrifuge. There are several other hazards like the instability within the equipment due the unbalanced rotor can be quite hazardous at those high operating speeds and cause injury and damage in a laboratory.

Thus it becomes very important to use the Centrifuge device safely since if the rotor does fail due to excessive mechanical stress caused at high rotational speed this can also result in flying metal fragments that can very easily injure the laboratory operator and damage the laboratory itself. Here are a few tips that should ideally be followed:

  • Make sure that the centrifuge bowls and tubes are dry prior to use, this is in fact quite important as well.
    Another factor to consider, especially when having multiple centrifuge devices is to match the set of tubes, buckets and other equipment to make sure they are of the correct specification.
  • Any material used along with the centrifuge should first be inspected thoroughly. For example the sample tubes should be inspected prior to use and if you notice a crack of some kind it should not be used under any circumstances.
    It is a good idea to make use of the centrifuge safety cups provided to prevent aerosol spills of potentially infectious materials.
  • There may be situations when a spill may occur and the sample tube material is infectious. In such a case it is advisable to wait for 10 minutes after the rotor has stopped before opening the lid of the centrifuge.
  • Over filling the samples tubes can also be one of the reasons for spills within the centrifuge device and thus it is best to avoid that.
  • Make sure the surface the centrifuge is placed on is flat and even so that there are no vibrations when the device is in use.
    In the case where you do notice some wobbling or shaking of the centrifuge while it is operational, it is necessary to pull the plug immediately. Failing to do so can damage the device and even cause injury.
  • One thing that the laboratory operator should always remember is to take special use while preparing the Centrifuge for use. The number of tubes in the rotor should always be even in order to balance the rotor. As an example if the sample being used in the centrifuge is of 15ml then a 15ml tube of water should b placed in the opposite section to balance the rotor. The density of the sample also needs to be taken into consideration. Thus the total mass of the tubes on both the sides should be similar. This is important since the centrifuge spins at a very high speed and any imbalance case permanently damage the centrifuge and has also the potential to cause injury to the operator.
  • It is important to follow the practice of correctly labelling the samples present in the laboratory. Though this does not affect the centrifuge directly since the centrifuge doesn’t really care for the labels, it is quite helpful within the laboratory itself. By labelling the tubes, the laboratory personnel are always aware of the contents of the tube and thus it is hard to mistake it for something else. In the case where the sample tube does contain a hazardous substance, the laboratory personnel will not be in the dark about the content and thus can handle the tube in an appropriate manner.


Thus it is very easy for things to go wrong even when using a relatively simple device like a centrifuge. Thus ideally it is safe for only proper and trained laboratory technicians to use this device. But even the technicians do over look some of the basic safety features at times and pay the price. The tips mentioned here are very useful for preventing such incidents from happening. This is a fairly big list of important points to keep in mind while using a centrifuge device though not the complete list of factors. For example it is also not advisable to open the lid of the rotor whilst it is motion and it is also a good practice to wear safety goggles while working with a centrifuge device. However the main safety issues have been mentioned here and should always be taken into consideration while using a centrifuge device.

A short note on the caring for your Medical Centrifuge

iFuge D06

A Medical Centrifuge is an instrument that spins samples at a very high speed. This forces the heavier particles to collect at the bottom of the tube. For example a Medical Centrifuge is extensively used for separating the cellular components of blood from the liquid so the liquid can be used for testing. The Medical Centrifuges vary in size, capacity and speed capability. Medical Centrifuges usually have a speed capacity of 0 – 2000 rpm and are capable of holding tubes ranging in size from 5 ml to 50 ml. The medical centrifuge used in the blood bank are often called serofuge and spin tubes with capacity of approximately 2 ml to 3 ml.

Maintenance of a Centrifuge:

Like every other medical instrument even the Medical Centrifuge requires regular maintenance. In addition to maintenance of the medical equipment, it is essential to also care for device after every use. Here are a few tips for maintenance:

  • The initial calibration of a centrifuge should always be performed by a qualified service technician.

  • In an ideal world the maintenance procedure should be carried out on a daily, monthly or annual basis.

  • One thing that should be followed to prolong the life of your centrifuge is to wipe the inside to the bowl with a disinfectant solution and rinse it thoroughly immediately after use.

  • To prevent from causing damage to the centrifuge it is a good idea never to use it when it is hot.

  • Things to look out for when the Centrifuge is in use is unusual vibrations, or noise, as well as deterioration of parts. When such cases are noticed it is advisable to stop the centrifuge device and remove the plug. In addition to this it is advisable to contact a qualified service technician.

  • In addition to cleaning the device after use it is also essential to have a monthly maintenance routine for your medical centrifuge. There are a number of things to include in your monthly routine like cleaning of the centrifuge housing, rotor accessories with a neutral cleaning agent. Typically the centrifuge device should be cleaned with a mild cleaning agent.

  • The monthly maintenance should be complemented with an annual maintenance. The ideal person to do this would be a qualified service technician.

  • The annual maintenance should include the cleaning of condenser coils, filter as well as the fan screens. The centrifuge brushes should be checked along with the bearings, timer, temperature and speed as well the electrical integrity.

  • There is a nut that secures the rotor to the shaft, make sure that this is not lose.

Repairs and fixes of a centrifuge:

There are several cases when you may need to repair or fix the medical centrifuge. If you are a laboratory technician then you must be more than familiar with spills and minor accidents that occasionally do occur. Here are few common issues and their fixes:

  • It often happens that during the operation of a centrifuge liquid from the tube spills on the centrifuge device. Such spills should not be ignored and should be cleaned immediately. The reason being that such spills can easily cause corrosion or damage.

  • The tubes used in the centrifuge do not last forever. They develop cracks over time. Using a tube which is cracked is extremely dangerous especially when using hazardous substances. These tubes can easily break while inside a centrifuge and cause a lot of damage. Thus such tubes should be replaced as soon you come across them.
