The invention is characterized by the provision of a base for all diameters, said base permitting the connection of stir drives as well as equipment for the dispersion and/or distribution of gas and/or liquids, and a contour for the fluid-tight connection to a corresponding flange on a reactor vessel component having one of the graduated diameters, whereby the reactor vessel components also has a flange at its other end permitting the connection of another reactor vessel component or it acts as a termination element.de608610620660patent1991-4118882
