2. An apparatus in which humans or animals are enclosed and which is revolved to simulate the effects of acceleration in a spacecraft.
tr.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.
[French, centrifugal, from New Latin centrifugus; see centrifugal.]

1. (Mechanical Engineering) any of various rotating machines that separate liquids from solids or dispersions of one liquid in another, by the action of centrifugal force
2. (Mechanical Engineering) any of various rotating devices for subjecting human beings or animals to varying accelerations for experimental purposes
(Mechanical Engineering) (tr) to subject to the action of a centrifuge
n., v. -fuged, -fug•ing. n.
1. an apparatus that rotates at high speed and separates substances of different densities.v.t.
2. to subject to the action of a centrifuge.
[1795–1805; < French, n. use of centrifuge (adj.) < New Latin centrifugus; see centrifugal]
A machine that separates substances of different densities by rotating them at very high speed. The denser substances are thrown farther outward than the less dense ones. A centrifuge can be used to separate cream from milk, or bacteria from a fluid.
