In the development of pharmaceutical, chemical and cosmetic products it is important that pilot plant processes operate as close as possible to the original plant to enable their later application in the actual production processes. For this reason laboratory and technical mixers must represent a smaller version of the original production plant. The homogenization mixer, for example, is designed so that the speed of the agitators is identical to that of high-capacity mixers. If not only the actual products of such test equipment but also the technical components prove worthwhile, they will be preferred when components are chosen for the production plant.
