The microbiology petri dish is a shallow transparent lidded dish. Most biologists use this dish to hold a growth medium where the cells can be cultured. These cells include bacteria, fungi, and small mosses. This is the most common type of culture plate used in the laboratory. It is widely used in biology laboratories.
The petri dish sizes come in cylindrical shapes with a diameter of 30 to 200 millimeters. The height of these dishes ranges from 1:10 to 1:4. These dishes are usually made of glass, and they are reused because of the heat-resistant glass, which can be sterilized appropriately at 120-160c.
Uses of Petri Dish
Petri dishes are widely used in biology for cultivating microorganisms such as bacteria, yeasts, and molds. These dishes are for those organisms which can easily thrive on a solid or semisolid surface.
Contamination detection and mapping
Petri dishes are used for visualizing the location of contamination on surfaces. Use them on surfaces of kitchen counters, utensils, clothing, food preparation equipment, or animal and human skin.
These mini Petri dishes are used for cultivating cells out of isolated cells from eukaryotic organisms.
