Petri Dish
Petri Dish
A Petri Dish (pronunciation: /ˈpiːtri/), also known as a Petri plate or cell-culture dish, is a shallow cylindrical glass or plastic lidded dish that biologists and chemists use to culture cells, such as bacteria, fungi or small mosses.
Etymology
The Petri Dish is named after the German bacteriologist Julius Richard Petri, who invented it in 1887 when working as an assistant to Robert Koch.
Description
A standard Petri Dish consists of two parts, a cylindrical bottom and a lid. The bottom part is slightly larger in diameter, allowing the lid to fit over it seamlessly. This design helps to both keep contaminants out and maintain a humid environment inside the dish, which is beneficial for the growth of the culture.
Usage
In a laboratory setting, a Petri Dish is typically filled with a growth medium like Agar to which cells or bacteria are added. The dish is then sealed and incubated to allow the cells or bacteria to grow. The resulting colonies can be observed and studied directly through the clear walls of the dish.
