What are petri dishes made of?
Petri Dishes. Petri dishes are shallow cylindrical containers with fitted lids that are designed specifically for microbiology or cell culture use. Petri dishes are typically made of borosilicate glass or clear plastics (usually polystyrene or polycarbonate) and come in a variety of sizes.
They can be disposable or reusable, with reusable types able to withstand repeated sterilization procedures (wet or dry).
A petri dish is a laboratory vessel used for microbial or cell culture. It consists of a flat disc-shaped bottom and a lid, and is usually made of glass or plastic. The culture dish material is basically divided into two types, mainly plastic and glass. Glass can be used for plant materials, microbial culture and adherent culture of animal cells. The plastic may be made of polyethylene. It is disposable and can be used repeatedly. It is suitable for laboratory inoculation, streaking, and isolation of bacteria. It can be used for plant material cultivation.
