Lab technology The process of separating fractions of systems in a centrifuge. See Axial centrifugation, Density gradient centrifugation, Ultracentrifugation.

cen·trif·u·ga·tion

(sen-trif'ŭ-gā'shŭn)
Sedimentation, by means of a centrifuge, of solids suspended in a fluid. After the process, supernatant fluid and sediment are separated.

centrifugation

a process in which particles in suspension are subjected to centrifugal forces by being spun in a CENTRIFUGE, so forming a sediment. Subsequent removal of the SUPERNATANT fluid from the sediment and subjecting it to higher speeds of centrifugation can enable particles of different sizes to be separated out and collected. Eventually the supernatant fluid will contain only soluble materials. In some types of centrifugation, the sample is layered on to a column of liquid (such as sucrose) of increasing concentration down the column, and centrifuged until bands are formed. In this way the molecules are separated by their different rates of sedimentation. see DIFFERENTIAL CENTRIFUGATION, ULTRACENTRIFUGE.

centrifugation (sen·trifˈ·y·gāˑ·shn),

n the process by which substances are separated by cen-trifugal force to increase the rate of filtration or sedimentation of two immiscible liquids or a liquid and a solid.

centrifugation

the process of separating lighter portions of a solution, mixture or suspension from the heavier portions by centrifugal force.

density gradient centrifugation
a procedure for separating particles such as viruses or ribosomes or molecules such as DNA in which the sample is placed on a preformed gradient such as sucrose or cesium chloride. Upon centrifugation either by rate zonal or equilibrium procedures, the macromolecules are 'banded' in the gradient and can be collected as a pure fraction.
