Glass and plastic petri dishes for ideal use in the science laboratory.
It (also known as a Petri plate or cell-culture dish) is a shallow transparent covered dish used by biologists to hold growth medium in which cells, originally bacteria, fungus, and small mosses, can be cultured. Julius Richard Petri, a German bacteriologist, is credited with inventing the container. It is the most often used form of culture plate. The Petri dish is a prominent object in biology laboratories and has infiltrated popular culture. The term is occasionally written in lower case, particularly in non-technical publications.
In biology, they are commonly used to produce microorganisms such as bacteria, yeasts, and molds. It is best suited to organisms that prefer a solid or semisolid surface.
