What are the techniques of homogenization?

Homogenization is a chemical technique through which components are constantly mixed that are not miscible among themselves, that is, that conventionally do not mix, in order to obtain homogeneous solutions or soluble suspensions. The final result will depend on the solutes that are mixed together as well as the type of equipment used for this technique. At present, the most commonly used instrument is the homogenizer.

Homogenizers are also called vortex mixers and were created by inventors Jack A. Kraft and Harold D. Kraft, when they worked as laboratory equipment manufacturers. After their invention, they filed the patent in April 1959 and it was granted in October 1962. Today, the same factory where they worked still manufactures the homogenizers.

Applications of homogenization

Homogenization is a technique that allows obtaining homogeneous solutions from solutes and solvents not miscible with each other. This technique is very useful in many fields of science, which is why the homogenizer is an indispensable equipment in every laboratory. The applications of the homogenization technique are shown below:

  • In the chemical and petrochemical industry, it is used for mixing reagents, solutes and solvents, or for emulsion optimization.
  • In biology and biochemistry, it is used for the breakdown of cells and tissues, without damaging the cell membrane.
  • In the food industry, it is used for the preparation of creams and sauces, as well as in the dissolution of salts and sugars.

Homogenization techniques

In homogenization different types of substances are combined in order to obtain a mixture that is uniform and consistent. Homogenization is usually used with solutes and solvents that are not miscible or barely miscible with each other. The process of homogenization can be carried out through several techniques:

  • Shearing forces produced by solids or liquids.
  • By gas cavitation.
  • By chemical and biochemical methods (hydrolysis or use of hypotonic media).


Since ancient times, a large number of technologies have been used to obtain homogeneous mixtures, among them mortars, which can still be seen in many laboratories today. Other less common methods include the use of blenders or crushers, however, the most effective technology is the homogenizer.

A homogenizer is an instrument used in laboratories for the homogenization of various materials, such as tissues, cells, soil samples, plants or food, among others. It has a very simple operation based on the creation of a vortex in the sample that allows the disintegration and obtaining of a homogeneous solution.

Operation of a homogenizer

The homogenizers are formed by an electric motor which is positioned vertically, this in turn is connected to a piece of rubber, which is usually located in the center of the equipment. When the rubber part is pressed, the engine of the equipment causes the rotation of the same, in this way the movement is transferred to the interior of the sample so that the solutes that compose it are mixed with each other. These equipment must be configured to have two types of operation, one continuous and one intermittent, when the rubber is pressed.

In the laboratory, during the use of the homogenizer, it is advisable to place it on a stable and level surface, for greater comfort and efficiency. On the other hand, the surface must also be completely clean, so that the feet of the equipment are tightly held and in this way avoid spills. It is also advisable to place it near a power source.
