A Petri dish for the culturing of micro-organisms comprises a lid (13) and a bottom container (11) having a substantially flat bottom wall (15) merging into an upstanding, substantially cylindrical, side wall (17) through a transition zone (19) extending between the bottom wall and the side wall. The transition zone includes: (a) a first straight section (21) adjacent the side wall which extends from the side wall toward the bottom wall at an angle A relative to the plane of the bottom wall, (b) a curved section (23) adjacent the first straight section; and a second straight section (25) adjacent the curved section which extends from the curved section to the bottom wall at an angle B relative to the plane of the bottom wall. The construction of the lid and the container permits an improved stacking when a plurality of Petri dishes are stacked and a uniform media bed with more uniform depth and improved retention of the media. |
