Laboratory centrifuges

Centrifugation is a mechanism for separating mixtures (in particular, those made up of solids and liquids of different densities) through their exposure to a rotating force of a certain intensity. Centrifugal force causes objects to move away from the center as they rotate. It is the same used by a centrifuge, an instrument capable of generating centrifugal force, to separate mixtures in a laboratory.

Centrifugation works by pushing the densest components of the mixture towards the point furthest from the axis of rotation and leaving the least dense at the closest point. This technique is in daily use by chemists, biologists, and other scientists. In other words, centrifugation forces the mixture to undergo a rotary movement with a force of greater intensity than the gravitational force, causing the solid or particles of higher density to settle.

This is one of the principles on which density is based: 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 settle.

The centrifugation process has a wide range of uses in all fields of our lives, especially in the medical field. Centrifugation devices have different uses. For example, 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 technique has become a fundamental step in the analysis of blood samples, especially in blood bank laboratories.

This is one of the newest techniques in the medical field to hold donated blood and "wash" it. To do this, you need this blood washing centrifuge, the high-end device your laboratory needs. The red blood cell flushing procedure is done when people need a blood transfusion. In this process, most of the plasma, platelets, and white blood cells are removed. These types of tests are also performed to see if the donor's blood is compatible with the recipient's blood or not.
