What is a 90mm Petri dish?
A 90mm Petri dish is a laboratory vessel used for the cultivation of microorganisms or cells. The 90mm Petri dish consists of a disc-shaped bottom and a cover, and is basically made of glass or plastic. Glass is mostly used for plant material, microbial culture and animal cell adherent culture. Most of the plastics are made of polyethylene materials, which are disposable or multiple-use, suitable for laboratory inoculation, marking, and bacterial isolation operations, and can be used for the cultivation of plant materials.
The 90mm Petri dish has been around for over a decade and yet the simple cell growing tools remain a permanent fixture in many laboratories around the world. The shallow cylindrical glass or plastic lidded dishes are most commonly used by biologists to make agar plates, which bacteria can be cultured upon.
What role do 90mm petri dishes play in the laboratory?
Due to their versatile nature, 90mm Petri dishes are one of the most common pieces of equipment found in laboratories. Not only does it provide an excellent environment for the growth of bacteria, yeast, mold, and viruses, but it has other uses as well. 90mm Petri dishes can also be used to observe insect behavior, observe seed germination, store samples and evaporate solvents.
