Centrifugation Separations sigmaaldrich

Under centrifugal force, particles move at different rates depending on their mass (2C). The speed at which particles sediment depends primarily on their size and mass instead of density. As the particles in the band move down through the density medium, zones containing particles of similar size form as the faster sedimenting particles move
