A centrifuge is used to spin fluids of different densities to separate various parts, commonly blood and DNA samples. Centrifuges are composed of the main body or housing and a spinning rotor. Tubes of cellular material suspended in liquid are inserted into the rotor and spun at various speeds to separate components. Centrifuges are used in medical, industrial, and research laboratories, as well as academic and clinical settings.
