Petri Dishes
Petri dishes are the standard consumable for cultivating microorganisms (bacteria, yeast, molds) or cell cultures. We offer a wide range: from sterile plastic (polystyrene) dishes of various diameters (e.g., 90mm), including vented and multi-compartment versions, to autoclavable borosilicate glass dishes. Do you need dishes for routine microbiology, cell culture (TC treated), or models with a counting grid? Find sterile and optically clear Petri dishes here.
