12PK Plastic Petri Dishes with Lids - 2.9" Diameter, 0.5" Depth - Molded in Polypropylene - Reusable, Autoclavable - Translucent - Eisco Labs

These work great they hold up in the autoclave and are easy to clean. I was happy enough I ordered a second batch

These are the only pp5 Petri dishes I can find and are worth getting over the single-use plates. There are 2 issues that I have with them though, they don't come pre-sterilized and the lid is a bit large for the bottom.

Great dishes, not as clear as the polycarbonate autoclavable ones but still easy to see inside of. I missed in the description that they do not come sterile and learned that the hard way. This is why you should quarantine dishes for a couple days after pouring to insure sterility.I assume these will be more durable than the polycarbonate ones and seem to not scratch too easily from a brush etc.

These are great! I ordered 50mm first but they are a little too small for me. The 75mm are easy to handle and have plenty of room for cultures to grow. I have pressure cooked them for 30 minutes at 15psi several times with no noticeable deterioration. Yeah, they are a little harder to see through than glass but they aren't fragile and they have a small ridge around the top of the lid so they can be stacked securely, unlike slippery glass dishes. According to my math, if i use the 5 times they will pay for theirself compared to disposable dishes. Glass dishes never even came close to paying for themselves because they always got broke right away, often an entire stack all at one time. I can't recommend these enough.

Product is exactly as advertised, though not entirely transparent/see-through. shape and fit of the lids over the bottom dish makes them less than ideal for any serious sterile agar work and makes them a pain to tape/parafilm.

I purchased these for a craft project (xmas presents for my lab mates). I needed smaller than average, clear plates. These fit the size bill and, from the listing photos, appeared to meet my needs for appearance, as well. Quick shipping got these to me in 2 days which I needed a week from Xmas. HOWEVER. Other than the size, these screwed me over. Do NOT trust the stock photos. Those do NOT represent the plates being sold in this listing. Unlike the hard, clear plastic of the dishes I'm use to in the lab, these are a softer plastic which means it lends itself to cloudiness. I mean, seriously, these things are almost white. If these were a book, they would be "The Fog" by Stephen King. You can see a little, like if there a dark blob inside, you would be able to tell, but any detail beyond that or any lighter colors would be hard to decipher through the hurricane of murky white dish. I added a photo to show a comparison between my glasses and the plate. Now assuming my glasses are clear, that is the difference between the plastic lenses and the plastic plate received. This is my biggest peeve of these plates as my project had to be altered (again) due to this not as describe product. I really hate misleading sellers. Makes it not worth the money when you need something.From reading the reviews before I bought these, I know some people mentioned the gap between the lid and plate. I tried to take a photo of that. There is some play there and they are tight in the least. If you lift by the lid, the bottom falls right out. It will even moved around the bottom if you circle it while closed. So, in a nutshell, not tight fit at all. I also added a photo with a quarter on the plate for size comparison for those who aren't great at thinking about size these really are.TL;DR If you really want these for a lab project, I'd pass like a hot potato; they will only bring you heartache and infection. If you want them for sprouting plants or such, they would work great unless you want to put the top on for seeds and get light through; can't guarantee that will happen, but maybe they grow best on cloudy days? Craft projects work good as long you don't plan to close it up; you will do hard work inside only to be unable to see it when the plate close up. Don't buy these small Stargates which will transport you work away to another dimension until you call it back. Very disappointed.

I love these things. Ive been looking for an alternative to the disposable dishes for a long time, and these are it. Specifically the 75mm size, Im sad to see that these are sold out right now, as I really want to order some more. The 75mm diameter fits perfectly in a quart size Twist n Loc container. I can fit 9 of them in a single container, and put them through an autoclave cycle for sterilization.Clarity is good. They stack well. They are light enough to hold together after parafilm wrapping. And are reusable.

I use these for bug collection and they are a good size to fit in my field pouch since I usually carry 4 or more with me. They are flexible and don't seem to crack like the others. This might be due to them being a different kind of plastic which is opaque. I wish they were more clear as it helps me to see the very tiny insects better. 4 stars instead of 5 because there is a gap in width between the top and bottom which allows the insects to crawl out even if I rubber band the petri dish.
