Sterile Agar plate - Petri dish - Grow Supplies

A sterile agar plate in a Petri dish is typically a clear, circular plastic or glass dish containing a solid growth medium made with agar, which appears smooth and undisturbed without any visible microbial colonies. It looks transparent to slightly opaque, often with a pale tint depending on the type of agar used. The plate is sealed or uncovered in a sterile environment to prevent contamination before inoculation. These plates are essential for cultivating microorganisms under controlled conditions in laboratories, ensuring a pure environment for studying or growing cultures.
