100mm Glass Petri Dish with Cover, Borosilicate Glass, Karter Scientific (Pack of 10)

So, I've bought 120 plates, half in 90mm and half in 100mm. There are imperfections and downright flaws with these plates, but at at fraction of the price of other plates, I can deal with it. I would say one in ten plates has a minor issues, like it is warped, and the lid doesn't sit flush, or there was a little piece of something stuck in the glass. I find it better to use plastic wrap to seal them because the gap would be difficult to cover with parafilm. Out of the 120, maybe five or so had something seriously wrong. Chipped, cracked, super deformed or super thin glass. I know how to handle a plate, and I put my thumb through one of them near the edge and I wasn't even putting a whole lot of pressure on it. If you want every plate to be perfect, don't buy these. If you can deal with some wonk, and want a good deal, go for it.

These arrived in good condition. They were packaged very well. I am so happy with the purchase that I am ordering 30 more dishes. Thank you for a good experience with these fragile items.

These look like they were cast in someone's garage by a 12 year old. They are all different heights and maybe 3 out of 10 pairs are square/level. It's not possible to stack multiple dishes because they are so uneven and deformed. All of them arrived undamaged, but after a single session in an autoclave, 2 pieces cracked - unfortunately not the malformed ones.I would recommend against buying these. After factoring in damaged and malformed pieces, the price per dish approaches soda lime dishes from more reputable and consistent vendors like Sigma.

One arrived chipped and I don’t think it happened in shipping. I could find the glass shard in the packaging. So someone packed and shipped a chipped glass laboratory product.

Packaging seemd adequate, doubled wrapped padding, 4 out of 10 were broken

I use these for my oil paint; I can put colors I am working with, mix, or whatever and then cover them to keep them for long periods of time. I do add poppy, walnut, or safflower oil to my paints which help from drying out. But, one very important trick, add a couple of drops of clover oil to the inside of the lid and place over the bottom. This keeps oil paints from drying out really well. Don't mix clover oil into the paint.

Five broken dishes 😠 5/10 broken! Whatever wasn't broken had deep scratches and was dirty and poorly made glass with chips, bubbles and divots. Poorly made and poorly packaged and shipped. I was actually surprised with the poor quality because I ordered a nice media bottle from this company and it was very well made.

Like most other reviews I bought these to replace disposable plastics. I will ordered 50 thinking some would get damaged during shipping. I'm happy to report 49 of the 50 made it to me in very nice condition. They are NOT steril mine came in paper wrap In a cardboard box.. I don't really mind I would have sterilized before use anyway. Lids fit well.
