It is a device used in the processes of separation of sedimentation of the liquid and solid components of a sample, this device generates rotational movements and through centrifugal force accelerates the decantation or sedimentation of the components of the sample, according to their density, there are different types of centrifuges, which pursue the same objectives.

In laboratories, centrifuges produce a rotation at high speeds, separating by layers the different materials that make up the sample and that generates that the densest elements of it are deposited in the lower part of the container and the lightest ones are kept in the upper part of it; the relative force of centrifugation is measured in multiples of gravity, and that by its physical size cannot be represented in units.

Types of Centrifuges a Laboratory May Need

Non-refrigerated Centrifuges

Centrifuges are used in laboratories for research purposes, to separate certain parts of a cell or DNA, commonly used in molecular biology to perform blood tests, on the other hand, they are used for the production of fuel, where centrifuges separate the product from sediments; a very important application is the separation of Ukrainian 235 from uranium-238.

They also serve to quantify the degree of fat or cream contained in the milk, for the elaboration of olive oil, since they are introduced into the horizontal centrifuge, where the oil is separated from the rest of the components; widely used in control laboratories and factories where they make juices where they control the level of their pulp; they are used in laboratories where they separate plasma from blood serum; allowing the use of accessories for centrifuges according to the analysis or research required to make creams, butters, among other products.

Refrigerated Centrifuges

The centrifugal force accelerates the sedimentation process of particles that have a tendency to do so spontaneously (those that have a density greater than that of the liquid), or in those that tend to float (density lower than that of the liquid).

The type of clinical procedure and the size of the laboratory are two very important factors when choosing a centrifuge. Although there are many models and types of centrifuges, their operation is always the same: all centrifuges rotate the samples around a fixed angle and separate fluids from solid substances by applying the sedimentation principle.

Centrifuges in operation

High-speed centrifuges are essential equipment for the isolation and characterization of multiple biological structures: from biomolecules, such as nucleic acids and proteins, to cellular organelles.

High-speed centrifuges are specialized centrifuges that reach maximum speeds between 18,000 and 25,000 rpm (they can generate around 60,000 g). They are refrigerated and normally have a vacuum system to avoid heating the rotor. This vacuum system allows them to have a more exact temperature control than those that do not do a vacuum. They are useful in the separation of cell fractions, but insufficient for the separation of ribosomes, viruses or macromolecules in general.
