A polystyrene petri dish is a shallow, cylindrical, lidded dish commonly used in laboratory settings for cell culture, microbial culture, and other biological applications. These dishes are made from polystyrene, a rigid and transparent plastic material that allows researchers to easily observe the contents inside.

Polystyrene petri dishes are lightweight, disposable, and cost-effective, making them ideal for use in microbiology, molecular biology, and tissue culture applications. They come in various sizes, typically ranging from 35 mm to 150 mm in diameter, to accommodate different experimental needs.

The smooth, flat surface of a polystyrene petri dish provides a suitable environment for cell attachment and growth. The lid helps maintain a sterile environment inside the dish, protecting the cultures from contamination. Additionally, the dishes are stackable, allowing for efficient use of space in the laboratory.

In summary, polystyrene petri dishes are essential tools in biological research, offering a convenient and reliable method for culturing and observing cells and microorganisms. Their versatility, affordability, and ease of use make them a staple in laboratories worldwide.

Polystyrene petri dishes are generally considered chemically suitable for use with a wide range of common laboratory reagents, solvents, acids, and bases. However, they may not be compatible with certain aggressive chemicals or organic solvents that can degrade or dissolve the material.

It's important to check the manufacturer's specifications for the specific petri dishes you are using to ensure they are suitable for the chemicals you will be working with. If you are unsure, it's always a good idea to conduct compatibility testing before use to avoid any potential issues.
