Description

A centrifuge is a laboratory device used to separate components of a heterogeneous mixture based on their density and particle size by applying centrifugal force. It consists of a rapidly rotating container, called a rotor, into which the sample is placed. When the rotor spins at high speeds, the denser components of the sample migrate outward towards the bottom of the tube, while lighter components move towards the top. Centrifuges are used in various scientific and medical applications, including separating blood components, isolating DNA or RNA, purifying proteins, and processing samples for diagnostic testing. They come in different types and sizes, including benchtop, microcentrifuges, and ultracentrifuges, each suited for specific research or clinical needs.
