摘要

Multi-purpose demonstration device includes carrier (10) accommodating inner space (13) enclosed by surrounding plates (11). A biological object is arranged in inner space (13). The bedding medium (30) fills up at least part of the inner space (13). The bedding medium (30) comprises a solidifying two-component silicon elastomer. Preferably at least part of surrounding plates (11) of the carrier (10) are provided with a set-off zone (12) (preferably the set-off zones (12) are made of methyl-methacrylate). Preferably at least part of the surrounding plates (11) forming the carrier (10) are made of glass.
