The centrifuge is an essential laboratory equipment, which generates rotational movements, in order to separate the components that constitute a solution. This equipment applies a sustained centrifugal force (that is, a force produced by rotation) to push matter out of the center of rotation.

Centrifugation is a technique governed by Stokes' law, who proposes that the particles settle more easily the greater their diameter and specific weight, and the lower their viscosity. Centrifugation is used to isolate or concentrate suspended particles in a liquid, taking advantage of the different displacement speeds depending on their shape, size or weight when subjected to centrifugal force. Centrifugal force is the force exerted on a body when it rotates around an axis.

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.
