Also known as a culture dish, a petri dish is a small glass dish that is fitted with a cover; the cover of the dish is meant to sit loosely on top, so there is still plenty of space inside. Inside of a petri dish, a scientist or student will place some type of culture, which will then grow and multiply.

How A Petri Dish Is Used

• When there is sufficient culture to study or use in an experiment, the contents of a petri dish will be used, along with other laboratory apparatus equipment, such as Bunsen burners and beakers, to test a hypothesis (educated guess) and draw conclusions.
• A typical petri dish is less than an inch deep; this glass plate can be used to incubate cells. Outside of laboratories, petri dishes may be used to incubate indoor pollutants in the home (such as mold), in order to detect which contaminants are in the air. Normally, a petri dish will be filled with a gel, and set aside in a warm, dark place to incubate; over a period not longer than a week, cells will appear in the petri dish, and molds will begin to grow. Whether used with a laboratory apparatus or not, a petri dish is highly effective for many expository science project

A laboratory apparatus simply is not complete without the addition of one, or several, shallow glass petri dishes and lids. In order to study the biology of germs, viruses, molds, and other living organisms, scientists and student need to add cells and culture to petri dishes, and store them properly during the incubation period. Other laboratory apparatus accessories, such as triangular glass jars and plate burners, may be used to prepare cultures for their inclusion into a glass petri dish. Petri dishes must not be contaminated during the incubation period.
