Laboratory centrifuges

The centrifuge is a laboratory equipment that generates rotational movements, it has the objective of separating the components that constitute a substance. Today there is a diversity of centrifuges that have different objectives, regardless of the type of research or industry.

Usually, the centrifuge is used in laboratories as a process for separating the sedimentation of liquid and solid components. Therefore, the centrifugation creates that the mixture undergoes a rotary movement with a force of greater intensity than the gravitational force, causing the sedimentation of the solid or particles of greater density.

This is one of the fundamentals on which the process is based is density: all particles, because they have mass, are affected by any force. Centrifugation imposes, thanks to centrifugal acceleration, an effect similar to gravitational.

Types of centrifuges to function properly in a research laboratory

Non-refrigerated centrifuge

Centrifugation has a vast range of uses in all fields of our life indirectly, especially in the medical field. Centrifugation devices have different uses. In the case of blood separation, DNA / RNA separation, cell culture separation and others such as the study of viruses, proteins, nucleic acids and polymers. These types of high-end centrifuges can separate mixtures of different size molecules or microscopic particles, such as blood cells. This practice is a fundamental step in the analysis of blood samples, especially in blood bank laboratories.

This is one of the fundamentals on which the process is based is density: all particles, because they have mass, are affected by any force. Centrifugation imposes, thanks to centrifugal acceleration, an effect similar to gravitational. The particles experience an acceleration that forces them to fixate.

Refrigerated centrifuges

Refrigerated centrifuges for laboratories are equipment used to achieve the sedimentation of the components in a homogeneous solution in their different densities at a predetermined temperature, for this they have a special design that subjects the solutions to centrifugal rotation and acceleration at a high speed by given time, movements with which the solution is separated into two fractions, all this process occurring at an appropriate temperature, since these centrifuges have a temperature control at which the sedimentation process is carried out.

To use a refrigerated centrifuge it is necessary to follow a series of steps that allow its safe operation. Although equipment of this type generally operates in the same way, it is advisable to consult the user manual provided by the supplier even if you have experience in the use of centrifuges.

Centrifugation: RPM vs. G Force

The relative centrifugal force or g-force (RCF) is the amount of acceleration that will be applied to the sample in the centrifugation process. It depends on the revolutions per minute (rpm) and the radius of the rotor. It is relative to the force of gravity on Earth. A well-written protocol or method should indicate that when using a centrifuge it should be done using g-force instead of rpm because the size of the rotors will be different depending on the brand and therefore the g-force will be different.

Unfortunately, not all protocols are accurately written and instructions are given incorrectly using rpm. Therefore, one has to convert g-force (RCF) into revolutions per minute (rpm) and vice versa. Some centrifuges automatically convert these units, others do not, but for those cases where they do not, there are formulas to calculate this.
