Subjection to sedimentation, by means of a centrifuge, of solids suspended in a fluid. SYN: centrifugalization.
- band c. SYN: density gradient c..
- density gradient c. ultracentrifugation of substances in concentrated solutions of cesium salts or of sucrose; at equilibrium, the medium exhibits a concentration (hence density) gradient increasing in the direction of centrifugal force and the substances of interest collect in layers at the levels of their densities. See isopycnic zone. SYN: band c., zone c..
- zone c. SYN: density gradient c..
