Centrifugation is known to have a vital role in the fractionation of many subcellular organelles. Furthermore, centrifugation is also useful in the fractionation of membrane fractions and membranes. Centrifugation also has applications in the fractionation of membrane vesicles. Chalk can be separated from water with the help of a centrifuge.

Centrifugation - Wikipedia

Differential centrifugation. Differential centrifugation is the simplest method of fractionation by centrifugation, commonly used to separate organelles and membranes found in cells. Organelles generally differ from each other in density in size, making the use of differential centrifugation, and centrifugation in general, possible.

Subcellular Protein Fractionation Kit for Cultured Cells

Subcellular Protein Fractionation Kit for Cultured Cells

Each kit has enough reagents to fractionate 50 cell pellets of 20 L each, equivalent to approximately 2g of cell paste. (For tissue samples, use our Subcellular Protein Fractionation Kit for Tissue.) The first kit reagent, when added to a cell pellet, causes selective membrane permeabilization, releasing soluble cytoplasmic contents.
