PYREX® Glass Petri Dish

Cultivation of microorganisms can take place on a gel-like nutrient medium, which is placed in a flat, round, transparent dish with lid (the so-called Petri dish). Due to the solid gel, mixing of the microorganisms is prevented and larger cell culture accumulations (colonies) can grow. Petri dishes are manufactured from borosilicate glass 3.3 using a special manufacturing process. They allow an even distribution of the culture medium and guarantee a distortion-free view. The lids of the Petri dishes rest directly on the lower part and thus prevent turbulence of the protruding air space. This is well suited for reactions with long incubation times, at high temperatures or with sensitive culture media.
