Our vented 90mm Petri dishes are perfect for making your own agar. We have sourced Petri dishes from many different factories and found a clear winner. Our plates are made from optical quality polystyrene and weigh 16 grams each, which is 25% heavier than most dishes you find. This makes them sturdier and can be stacked higher. They come in easy tear sleeves and are sterilized and ready to use.
