Soccerene 20-Pack 60mm Glass Petri Dishes with Lids Tissue Culture Plate, Autoclavable Borosillicate Glass

I now am up to 120 of these. I really like the thick walls, high sides, and compact diameter. None have come broken. A few had minor defects all of which are in areas covered by parafilm anyway. Love them.Update : I still love these but I have to note my last box came full of rejects (not symmetrical) and broken lids. Still I had a lot of good boxes before I hit a bad one. Oh well

Good price, well packed. Arrive none broken. Top is quit a bit bigger than bottom but with a little finesse, this can be taken care of when you tape them. I like these and will order again if I need more.

3-4 stars. Arrived quickly but 2 bottoms were broken.Bottoms appear to be thinner than the sides.Not returning because I need to put them to use ASAP.Good price, I’ll give them another shot.But if you need 20 for scientific or classroom purposes I suggest you buy 40.

If you need some small dishes for hobby biology / mycology on a budget these will do the trick. One dish arrived chipped, another arrived with a small crack. The remaining 18 were perfectly fine. If you're looking for something fancy, look elsewhere, but these are just fine for my needs. I haven't autoclaved or used them yet but upon inspection they seem to be at least the same quality as the united scientific dishes I've gotten for more than double the price. Worth it for me.

Quite sturdy for the price.

I ordered these to run experiments with some tissue cultures and to prep for some shitake and oyster patches in the spring. I ordered from this same company last year. Those 90mm dishes broke very very easily. I lost a good number in transit (which the company refunded me for promptly). I lost a lot more of them by the end of last spring. Some breaks couldnt have been avoided, while other were clearly my fault. Regardless, I only have a few of those dishes left.I decided to go smaller because for the most part I dont need 120mm or 90mm of space to work with and its just a waste of whatever media I'm using. The tissue culture media is not particularly cheap.As I said in my headline, I ordered 40. I did that so I had atleast 20 to work with. I dont know if its because the dishes are smaller, or that they were just packaged better, but all of them survived transit. I think it may have been a little bit of both. Anyways they are the perfect size and they seem hearty and thick. If they start spontaneously imploding during use I'll update the review. But as of now, I couldnt be happier with them.

These definitely are not borosilicate glass, they should be able to withstand a little heat, but when I applied heat to them, increasing 15degrees Fahrenheit every 5 minutes, each one of them shattered before breaching 115!

Well made, well packaged. Just be aware that these dishes are smaller than a standard Petri dish.
