Sublimation Apparatus

    Sublimation is a terrific way to purify volatile solids. In general, the material to be purified is placed in a flask and then heated under dynamic vacuum or atmospheric pressure. The material slowly escapes to the gas phase, leaving impurities behind, and then deposits on an air, water or cyrogen-cooled condenser. For more about the practical aspects of sublimation and handy tips, be sure to consult the Sublimators Page of our Glassware Gallery.
