centrifugation
Separation by spinning
Centrifugation is the process of separating substances by spinning them at high speed.
Denser components move outward while lighter ones stay closer to the center.
The technique is standard in laboratories for separating blood components, isolating DNA, or purifying samples: After centrifugation, the sediment collected at the bottom of the tube.
