Abstract
An apparatus for growing anaerobic microorganisms is provided having a dish top that contains a sealing ring upon which the media surface in the dish bottom rests when the apparatus is inverted. The contact between the sealing ring and the media surface forms a seal that traps the gas in the headspace between the media surface and the inside of the dish top. A oxygen reducing agent can also be incorporated into the media together, in some instances, with a substrate which react with oxygen in the media and with oxygen in the headspace thereby creating an environment suitable for growing anaerobic, microaerophilic and facultative anaerobic microorganisms.
Claims20
A culture dish assembly comprising:
- a first dish having a wall and a side wall extending therefrom to define a cavity;
- a second dish having a wall and a side wall extending therefrom that cooperate with the first dish to form a non-sealed assembly in a first orientation of the first and second dishes in which the second dish is positioned on top of the first dish, and a closed headspace in a second, inverted orientation of the first and second dishes.
A culture dish assembly comprising:
- a first dish having a wall and a side wall extending therefrom to define a cavity, the side wall of the first dish tapering radially outward as it extends from the wall;
- a second dish having a wall and a side wall extending therefrom that cooperate with the first dish to form a non-sealed assembly in a first orientation of the first and second dishes and a closed headspace in a second, inverted orientation of the first and second dishes.
A culture dish assembly comprising:
- a first dish having a wall and a side wall extending therefrom to define a cavity;
- a second dish having a wall and a side wall extending therefrom that cooperate with the first dish to form a non-sealed assembly in a first orientation of the first and second dishes and a closed headspace in a second, inverted orientation of the first and second dishes, the side wall of the second dish including first and second legs defining an annular recess therebetween, the first leg tapering radially outward as it extends substantially perpendicular from the wall.
