Molecular sieves, 4A, belong to the category of desiccants, designed to adsorb molecules of a specific size or larger. Comprised of a crystalline alumino-silicate material, it possesses pores measuring about 4 angstroms, conveniently matching the size of a water molecule. The utility of Molecular sieves 4A is extensive in scientific research, finding applications in chromatography, biochemistry, and various laboratory experiments. Its versatility includes deployment as a desiccant in chromatography, acting as a stationary phase in liquid chromatography, and functioning as a sorbent in solid-phase extraction. Furthermore, it proves valuable in biochemistry for the separation of proteins and other biomolecules, as well as in various laboratory experiments for the purification and isolation of chemical compounds.
