Cesium sulfate is used for equilibrium density gradient centrifugation, one of the most useful tools for fractionation and characterization of macromolecules, such as DNA. Cesium sulfate can be used as catalyst.
Cesium sulphate is the inorganic compound and salt with the formula Cs2SO4. It is a white water-soluble solid that is used to prepare dense aqueous solutions for use in isopycnic (or "density-gradient") centrifugation. It is isostructural with potassium salt
