how to works centrifuge basic principle - centrifuge animation

A centrifuge is a device used in science to separate suspensions by density. The more dense particles separate out and migrate to the bottom of the test tube, while the lighter particles move toward the top. The machine is round, and has holes into which test tubes can be inserted. Then, a lid covers the top of the machine and it can spin using its motor at a very high speed. If someone wanted to separate blood into its components red blood cells, white blood cells, platelets and plasma, they would use a centrifuge. The plasma would be floating on the top because it has the lowest density. It can be used to separate organelles from cells and to isolate nucleic acids. These are some examples of how a centrifuge can be used The term centrifuge can refer to a machine that houses a rapidly rotating container to separate its contents by density (noun) or to the act of using the machine (verb). The modern device traces it origins to a spinning arm apparatus designed in the 18th century by engineer Benjamin R
