Petri dish

Related people

The Petri dish is one of the most universally used pieces of equipment in bacteriological laboratories. It is a shallow, cylindrical dish made of plastic or glass with a cover, used for tissue cultures and to hold solid media for culturing and sub-culturing bacteria. The monument to Koch in Berlin shows him carrying a Petri dish.

A similar dish was described by André Victor Cornil (1837-1908) and Victor Babès (1854-1926), and by Nicati and Rietsch. Both descriptions in 1885.
