Petri dishes are shallow, flat laboratory vessels used for culturing, observing and analysing microorganisms, cells or small samples. In chemistry, they are commonly used for crystallization experiments, drying solids and observing small quantities of compounds. Made from durable materials such as borosilicate 3.3 glass or high-quality plastic, petri dishes provide clear visibility and a controlled environment for reliable experimental outcomes. Widely used in research, industrial, quality, and teaching laboratories, they support diverse laboratory applications.
