What is a Centrifuge?
- 24, Sep 2021 10:37
A Centrifuge is a laboratory tool that is useful in separating particles by carrying out a deposition or sedimentation process based on the density solution differences. The working process is by placing the sample into the rotor by utilizing and applying a force perpendicular to the spin axis. The faster the rotation on the spin axis, the more the result of the deposition process or sedimentation will get, and vice versa.
There are 3 components of a centrifuge, such as rotor, driveshaft, and motor. The first component, the rotor, is a place to put the tubes, vials, bottles, or other containers that can be used to carry out the centrifuge process. The second component, the drive shaft, is the side part of the tool that can support / hold the rotor upright and is connected to the motor. Last, the third component, the motor, is the part that has the control to turn on and turn off the rotor system, without the motor, the rotor will not be able to start, and the centrifuge process will not be able to run.
There are two types of rotors, fixed rotor and swing-out rotor. Centrifuge with a fixed rotor can permanently attach the sample tube to the rotor with a tilt angle of about 450 and has a fast and large rotation speed. The precipitate or sediment formed will not be too dense and will have a sloping surface, so the liquid particles are susceptible to re-dissolving when the tool stops working.
Meanwhile, the centrifuge with a swing-out rotor can attach the sample tube freely to the rotor, so that the tube will follow the movement of the rotor. The swing-out rotor has a rotation speed that is not fast and quite low, so the precipitate or sediment formed will be solid and horizontal, it will make the liquid particles not easily decomposed when the tool stops working.
Types of Centrifuge
The Centrifuge has various functions depending on the field, like health, biology, chemistry, food, and many more. Due to the different functions of using the centrifuge, it also makes the centrifuge has various types, here are some types of centrifuge tools:
- Benchtop Centrifuge. The most widely used type and often found in laboratories, have various rotation speeds. Benchtop centrifuge is divided into 3 types, namely swinging bucket, fixed, and continuous flow.
- Refrigerated Benchtop Centrifuge. The type that is often used to perform the process of separating particles against temperature in living cells, animal cells, and protein cells. Has a variety of rotational speeds and can accommodate various volumes (milliliter – liter).
- Clinical Benchtop Centrifuge. Used to separate components of blood cells and other body fluids. It has a fairly low rotation speed, and has a similar tool size like the blood container tube.
- Microcentrifuge. This type is also widely used in laboratories. Can only accommodate small volume tubes, and can adjust the temperature.
- Vacuum Centrifuge. This type is used to carry out the process of particle separation or purification of samples such as peptides and proteins. Vacuum centrifuge uses centrifugal force, temperature, and air in carrying out its process.
