Petri dishes are shallow cylindrical glass or plastic lidded dishes that biologists use to culture cells such as bacteria or small mosses. Modern Petri dishes usually feature rings and/or slots on their lids and bases so that when stacked, they are less prone to sliding off one another. Multiple dishes can also be incorporated into one plastic container to create a "multi-well plate". While glass Petri dishes may be reused after sterilization (via an autoclave at 121 C for about 15-20 minutes in the case of moist heat sterlization or one hour's dry-heating in a hot-air oven at 160 C, for example), plastic petri plates are usually disposed after experiments, since cultures might contaminate each other. Petri dishes are often used to make agar plates for microbiology studies. Petri dishes are also used for eukaryotic cell culture in a liquid medium or on solid agar. They are used in immunodiffusion studies when partially filled with agar or agarose gel. Empty Petri dishes may be used to observe plant germination or for other day-to-day laboratory practices such as drying fluids in an oven and carrying or storing samples. Their transparency and flat profile also mean they are commonly used as temporary receptacles for viewing samples, especially liquids, under a low-power microscope.
