  • n. An apparatus consisting essentially of a compartment spun about a central axis to separate contained materials of different specific gravities, or to separate colloidal particles suspended in a liquid.
  • n. An apparatus in which humans or animals are enclosed and which is revolved to simulate the effects of acceleration in a spacecraft.
  • transitive v. To rotate (something) in a centrifuge or to separate, dehydrate, or test by means of this apparatus.

  • n. A device in which a mixture of denser and lighter materials (normally dispersed in a liquid) is separated by being spun about a central axis at high speed.
  • n. An apparatus in which humans are spun to simulate acceleration in an aircraft or spacecraft.
  • v. To rotate something in a centrifuge in order to separate its constituents

  • n. an apparatus having containers for liquids arrayed around a central pivot and rotated at a high speed, thus generating centrifugal force on the liquid, and separating substances (such as particles of solid or globules of an immiscible liquid) mixed together in suspension within the liquid. Suspensions which would settle only very slowly or not at all under gravity can be made to separate quickly in such a device.
  • transitive v. to drive out; to subject to the action of a centrifuge.

from The Century Dictionary and Cyclopedia

  • To submit to very rapid rotatory motion in a centrifuge or centrifugal machine in order to separate suspended solid particles from a liquid, or two immiscible liquids of different densities from one another.
  • n. A centrifugal machine; specifically, a form of centrifugal machine employed to separate the solid particles suspended in a fluid, such as the blood or urine.

  • Another are very, very high speed rotors -- so-called centrifuge -- which store energy not electrically like a battery or by, say, having hydrogen and oxygen separated, which you then put together in a fuel cell, but in the fly wheel you just have this mechanical energy stored up.
