A Petridish (alternatively known as a Petriplate or cell-culture dish), named after the German bacteriologist Julius Richard Petri, is a shallow cylindrical glass or plastic lidded dish that biologists use to culturecells – such as bacteria – or small mosses.
Petri dishes are essential for microbiology studies, used to create agar plates filled with nutrients, blood, salts, carbohydrates, dyes, indicators, amino acids, or antibiotics. After the agar cools and solidifies, they are inoculated with microbes. Virus cultures require a two-stage inoculation with bacteria as hosts.
Petri plates are incubated upside-down to prevent airborne contamination and condensation issues. They are also used for eukaryotic cell culture, observing plant germination, studying small animals, drying fluids, and viewing samples under a microscope due to their transparency and flat profile.
