Sublimation & Purification Equipment

            

Feature

This equipment carries out sublimation and purification of materials such as luminous materials for organic EL
displays in order to increase their purity. By utilizing evaporation (sublimation) temperature, only luminous
substance is sublimated from the mixture of luminous substance and impurities in vacuum state. It is then
extracted in high-purity condition after re-condensed in low-temperature section. Since heat is applied in vacuum
state, processing temperature may be low. It is also possible to restrain electricity needed for heating as well as to
prevent deterioration of luminous substance.
Various types of equipment from small-type for experimentation to large-type for mass-production are available
for selection.
