Product type
Sterile Petri plates are shallow, flat dishes made from glass or plastic, designed for the culture of microorganisms. They are typically composed of polystyrene or polypropylene, which provides a clear view of the contents and allows for easy handling. These plates are pre-sterilized to eliminate contamination, making them essential for laboratory use in microbiology, cell culture, and various biological experiments.
