Centrifuge is an instrument for separating materials, especially tiny particles suspended in liquid. The physical principal standing behind the method is the existence dependency between the aggregated material on walls of the centrifuge and the mass of its particles: With the rotation of the centrifuge, the particles in it are pushed toward the wall, but their density is in decline as they move away from the side – Materials with higher density, e.g. heavier, move and accumulate near the bottom of the test tube.
This action is called centrifuge and it’s being used much in biological research, in order to separate different materials. Example: use of centrifuge to isolate specific cell membranes or whole cells as part of creating the karyotype image.
Centrifuges in the industry
CSK Group the laboratory equipment suppliers explains the needs of centrifuges in the industry.
In certain industries centrifuges use to to separate the components of different specific mass mixed with a mixture. For example: in the process of uranium enrichment centrifuges are used to separate the two isotopes of the uranium in very high speed despite the tine mass difference between them. Another example is in dairy while using a centrifuge to separate the cream from the milk.
