Petri Dish is a category of laboratory equipment essential for microbiological research, cell culture, and other biological experiments. These dishes are typically made of high-quality glass or plastic, providing a sterile environment for growing microorganisms or cells. Common products in this category include standard Petri dishes, divided Petri dishes for multiple samples, deep Petri dishes for larger cultures, and specialized dishes with grid markings for colony counting. They are widely used in research labs, educational institutions, and pharmaceutical industries for tasks like antibiotic testing, toxicity studies, and bacterial cultivation. The dishes often feature stackable designs, airtight lids, and autoclavable materials for repeated use and contamination prevention.
