What are petri dishes made of?
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.
Can you reuse plastic petri dishes?
These plates are serious and made for being reused over and over. You cannot sterilize other petri dishes in an autoclave because they will melt. These PP plastic ones will not melt and can be used again and again.
How is petri dish sterilized?
