an apparatus that rotates at high speed and by centrifugal force separates substances of different densities, as milk and cream.
Also, centrifugalize. to subject to the action of a centrifuge.
any of various rotating machines that separate liquids from solids or dispersions of one liquid in another, by the action of centrifugal force
any of various rotating devices for subjecting human beings or animals to varying accelerations for experimental purposes
(transitive) to subject to the action of a centrifuge
1887, “a centrifuge machine,” originally a machine for separating cream from milk, from French centrifuge, from noun use of adjective meaning “centrifugal” (1801), from Modern Latin centrifugus (see centrifugal).

An apparatus consisting essentially of a compartment spun about a central axis to separate contained materials of different densities, or to separate colloidal particles suspended in a liquid. v. cen·tri·fuged, cen·tri·fug·ing, cen·tri·fug·es
To rotate something in a centrifuge or to separate, dehydrate, or test by means of this apparatus.
A machine that separates substances of different densities in a sample by rotating the sample at very high speed, causing the substance to be displaced outward, sometimes through a series of filters or gratings. Denser substances tend to be displaced from the center more than ones that are less dense.
