摘要

AHP-7615 A mixture of at least two liquid compositions, each having a material which is incompatible in the presence of moisture with a material in the other liquid composition, is cooled to a temperature slightly above its freezing point. The cooled mixture is charged into a container cooled substantially below the freezing point of the mixture so the mixture freezes instantly. The frozen mixture is lyophilized to provide a mass of dry matter.
