使用Cesium sulfate is used to prepare dense aqueous solutions for use in isopycnic centrifugation. It is also used for crystal growing purposes.
使用Cesium sulfate is the basic raw material for the preparation of various cesium salts, and can be used in trace analysis of aluminum and berkelium analysis reagent. It is often used as a liquid medium for density gradient centrifugation to separate and extract nucleic acids, suborganelles and plasmids [4].
純化方法Crystallise it from water (0.5mL/g) by adding ethanol and cooling.
