These disposable
petri dishes are made of optically clear polystyrene for easy reading. They
are available with stacking ring or with conventional flat bottom. The smaller
petri dish is ideal where accurate bacterial count and microscopic work are
required. The larger dish is excellent for anti-microbial studies. Venting
ridges prevent condensation on the inside of the lid.
