Abstract

The invention relates to an apparatus for the continuous preparation of photographic emulsions by a continuous flow process, in which a volume stream entering a pipe system flows successively through the various sections of this system corresponding to the individual stages of the process, such as the inlet points for introduction of the volume streams, mixing paths and ripening paths.
