Polystyrene Petri Dish with Lid, 60mm, Sterile (Pack of 26)

I used these to put jello in. My son had a science themed birthday party.

They are what they are. Good price and only one was lightly cracked on arrival.

Worked out for our purposes.

Product description is clear and accurate. I didn't realize that it's probably better not to have a vented dish like this because I think the sterile environment that I want and need is not possible unless these are sealed afterward in some type of bag or other means.When I did a sterilization run for some of my equipment, this dish melted and looked like a potato chip after 30 minutes in the pressure cooker so I cannot use this In a pressure cooker.

Great Product only thing Is i ordered them STERILIZED and came with a puncture in the bag, doesn’t seem like a big deal but sterile work is extremely sensitive, after some time in a uv sterile chamber I was able to use them with only a few losses.

These are the smaller plates but work well!

Chips of plastic, loose fitting, some parts are warped

A couple of dishes were cracked for me too. This seems like a common issue. Also, I would have preferred to have them packaged either in one long stack or two individuals. Getting them out of the bag is annoying and a little riskier because they're packaged with both stacks in the same large bag.It's fine, whatever. If you just want a couple of dishes then go for it. Next time, I think I'll spend a little more per dish and get a larger quantity from a better source.
