What Is A Petri Dish

A petri dish is a laboratory vessel used for microbial or cell culture, consisting of a flat disc-shaped bottom and a lid, generally made of glass or plastic. The materials of petri dishes are basically divided into two categories, mainly plastic and glass, and glass can be used for plant material, microbial culture and adherent culture of animal cells. The plastic ones may be polyethylene materials, which are disposable and multiple-use, suitable for laboratory inoculation, streaking, and bacterial isolation operations, and can be used for the cultivation of plant materials.
