Centrifugation is an important separation technique in different chemical laboratory analyzes. A centrifuge is a centrifugal device that rotates at high speeds to create a centrifugal force, allowing components of a solution to be separated. Laboratories use centrifuges to separate heterogeneous mixtures, such as liquid and solid, removing any contaminants, and it is also widely used for the preparation of samples for laboratory tests.
One of the most common applications of centrifuges is solid-liquid suspension separation. This is used to separate the components of a liquid. This is done by placing the suspension in a container that is placed in the centrifuge rotor. The centrifugal force then causes the separation of the components. Many liquid-based products with separate concentrations can be found, including serum, milk, coffee, and fruit juice.
What other application does the centrifuge have in the analysis laboratories?
Another common application of centrifugation is liquid filtration. This can be useful to remove certain types of impurities, e.g., sediments, fats, salts or other materials suspended in the liquid. The solution is placed in the centrifuge rotor, which generates a centrifugal force to separate the impurities from the liquid. This technique works best when heavy materials are suspended in the liquid.
Many labs find ultracentrifugation useful for separating one of their most complex applications. This technique seeks to separate components within a fluid such as small particles, macromolecules, lipoproteins or blood cells. The key step of ultracentrifugation is to achieve high speeds with a centrifuge to concentrate these particles in the background. What ultracentrifugation does is it further increases the force that makes particles settle.
There are also scientific applications for the use of centrifugation. These include experiments to provide an idea of the different viscosity of liquids under different pressure and temperature conditions, as well as studies to determine the composition of different mixtures of liquids. This information is important for many industries, such as pharmaceuticals and cosmetics, to understand how different components behave under varying conditions.
Centrifuge as a support for analysis in laboratories
Centrifuges can also be used to perform sample dehydration. This technique requires the preservation of the sample structure, which is especially useful for materials that are susceptible to decomposition due to drying during the process. This is especially useful for tissue preservation and for medical centers that perform biopsies. Centrifuges are also useful for preparing samples for laboratory analysis. By centrifugation, the solid phase can be separated from the liquid phase, allowing the components to be analyzed individually.
This is also used to separate components in samples of fertilizers, food, beverages and pesticides to determine their composition. Finally, the centrifuge is widely used for the separation of cells present in various biological fluids, mainly blood. Fluids contain a variety of cells, including red blood cells, white blood cells, white blood cells, and red blood cells.
By using centrifugation, these cells can be separated to study their composition and characterize their functionality. In conclusion, many typical applications can be made with a laboratory centrifuge. These include mixtures separation, suspensions study, fluid filtration, scientific analysis, sample dehydration, preparation for laboratory analysis, and cell separation. These applications are very important in many laboratories, as they allow students to study the materials with great precision.
