Centrifugation is a laboratory technique used to separate components of a mixture based on their density. This process involves spinning samples at high speeds in a machine called a centrifuge. The centrifugal force generated causes denser materials to move outward, settling at the bottom, while lighter components remain suspended. This method is commonly used in various fields, including biology and chemistry, to isolate cells, proteins, or other substances from liquids. For example, in medical laboratories, centrifugation helps separate blood components, such as plasma and red blood cells, for further analysis or treatment.
