Differential centrifugation is suitable for crude separations on the basis of sedimentation rate, but more fine grained purifications may be done on the basis of density through equilibrium density-gradient centrifugation. [2] Thus, the differential centrifugation method is the successive pelleting of particles from the previous supernatant ...
Differential centrifugation is the simplest method of fractionation by centrifugation, [9] commonly used to separate organelles and membranes found in cells. Organelles generally differ from each other in density and in size, making the use of differential centrifugation, and centrifugation in general, possible.
This differential speed between the two is accountable for the sedimentation throughout the decanter centrifuge cylinder. A high differential speed results in a smaller residence time of the cake settlement, so it is necessary to keep the cake thickness to a minimum to avoid impairing the discharge quality.
Laboratory centrifuge. There are various types of centrifugation: Differential centrifugation, often used to separate certain organelles from whole cells for further analysis of specific parts of cells; Isopycnic centrifugation, often used to isolate nucleic acids such as DNA
Microsomes can be concentrated and separated from other cellular debris by differential centrifugation. Unbroken cells, nuclei, and mitochondria sediment out at 10,000 g (where g is the Earth's gravitational acceleration), whereas soluble enzymes and fragmented ER, which contains cytochrome P450 (CYP), remain in solution.
Differential centrifugation. Fractionation is a separation process in which a certain quantity of a mixture (of gasses, solids, liquids, enzymes, or isotopes, or a suspension) is divided during a phase transition, into a number of smaller quantities in which the composition varies according to a gradient.

In the life sciences, a special technique called density gradient separation is used for isolating and purifying cells, viruses and subcellular particles. [5] Variations of this include Isopycnic centrifugation, Differential centrifugation, and Sucrose gradient centrifugation.
