Laboratory centrifuge, which one to choose at the best price?

November 2, 2021

First, it is important that you know that a laboratory centrifuge is basically what we know as a tabletop centrifuge , this because its size is not exaggerated. An example of this type of centrifuge are those that are used in clinical laboratories to perform blood samples and are even used in certain industries to check the quality of products such as: juices, soft drinks and wines.

These centrifuges are really very interesting and at the same time the use that can be made of them makes them important. Below we will explain everything you need to know about this tool.

Parts of a laboratory centrifuge

To be able to break down this point, it is convenient that we divide the parts of the centrifuge between its physical components and its functional components, let’s see it.

Physical components

The base of the laboratory centrifuge consists of a chamber, which is in charge of managing the same development of the centrifugation. This camera fulfills 3 important functions and those are:

  1. Take care of the samples and prevent them from breaking , which would not be difficult to happen if they were touched with some other object at the time it is rotating, especially due to the high speed.
  2. It guarantees that the person in charge of handling the centrifuge does not suffer any damage . Remember that this tool rotates at 2,000 rpm and therefore, an impact with someone would cause serious damage.
  3. It ensures that air currents do not enter the interior of the machine, as this could damage its operation.

Now, another component of the laboratory centrifuge is the tube holder , which would basically be the place where the test tubes aimed at the samples to be centrifuged should be placed.

For its part, the rotor is in charge of allowing the samples to rotate; In addition, this component is specially designed to be able to resist deterioration caused by rubbing.

Finally, as the last physical component we will find the cover, it is in charge of avoiding accidents if the machine has a fault, how do you do it? closing.

Functional components

There are 7 functional components that a laboratory centrifuge has, those are:

1. Switch . It allows or, on the contrary, denies the entry of electrical current to the machine, just like any other switch you know.

2. Speedometer . Thanks to this component we can adjust the speed of the machine according to what we want or need. Keep in mind that the space between each sample will largely depend on the speed you indicate on the speedometer.

3. Timer . This instead allows us to adjust the total time in which the machine will remain in operation, so that we can not worry about it if we need to do something else.

4. Brake . The brake will give us the opportunity to stop the centrifuge in case something unforeseen arises.

5. Tachometer . The tachometer tells us how fast the rotor is turning; practically fulfills the same function as in a car.

6. Vacuum system . This component prevents friction with air; If it were not for the vacuum system, the equipment would not fulfill its function in the same way, because in addition to being much slower, the result of the samples could change to a certain extent.

7. Cooling chamber . This chamber is a system of constant cooling and they only make up the ultracentrifuges, which rotate at a higher speed than the common ones.

How to run a laboratory centrifuge?

There are certain measures that must be taken in order to have a laboratory centrifuge and they ensure that it will work optimally, so below we will divide it into several steps to make it much easier for you to understand:

1. Firstly, it is recommended to find a space to place the centrifuge where it is alone, that is, that there are no other equipment on the same table; This recommendation is due to the fact that the vibration produced by the centrifuge is so high that it can lower the performance of another machine that is nearby.

2. The centrifuge tube holders must be completely empty and above all perfectly adjusted to the machine.

3. The rotor needs to be balanced.

4. The lid must be closed.

5. Make sure you set the correct speed.

6. Set the time on the timer.

7. Turn on the machine.

8. Do not lift the lid while spinning.

9. Return after the centrifugation time has passed.

10. Verify that the machine is completely without moving, raise the lid and take the tests.

It is very important that you carry out each step to the letter to avoid possible accidents.


  • Do not move the centrifuge while it is running.
  • Do not use the machine to centrifuge those substances that are explosive or extremely radioactive.
  • Be careful that nothing hits the centrifuge while it is running.
  • If at any time you notice that the tube holder is damaged then replace it immediately .
  • Before you start the machine, check what is the highest speed and density at which your centrifuge can spin.
  • Make sure the tubes are able to withstand the temperature at which you will need to centrifuge. The longer the centrifugation time and speed, the greater the resistance of the tubes should be.
  • In the event that the electricity goes out, you must make sure that the machine has completely stopped working in order to proceed to open the lid.
  • If it happens that the centrifuge becomes contaminated, either with impurities or radioactive agents, you must stop the machine and do a very deep cleaning .
  • Always check that the machine is properly leveled, only then can you allow it to have a longer use time and to work efficiently.

The 5 best laboratory centrifuges

We will provide you with a list of the 5 best laboratory centrifuges that you can find in the current market:

  1. Servo Spin Next.
  2. Edulab 153–001 ISG.
  3. Steinberg Systems SBS-LZ-4000.

If you need a laboratory centrifuge, any of the above are highly recommended.
