Weewooday Glass Petri Dishes with Lids Autoclavable High Borosilicate Petri Dishes Lab Supplies for Science Biology Project, Experiments, Clear, 90 x 20 mm

These were just delivered. I haven't used them yet. They arrived well packed, gleaming clean, and unbroken. The glass is very clear and transparent and free of obvious imperfections. The lids are slightly oversized but fit easily. I think they will do nicely for my application.

Good

The product looks to be quality. I was disappointed at the packaging, however. There was tissue-paper between each dish and between the dishes and their lid, but there was no padding of any kind around the items in their box. Since they fit too loosely in the box in two vertical stacks instead of one horizontal stack, there was enough free space that the dishes were able to move around and one arrived broken. Not a pick and pack issue, as the shipping box did not have any free space.

I took the chance with these after reading about how some came broken and others none were broken. I was willing to except that one may break maybe even 2 but when I received 4 broken out of the 10, that was a bit ridiculous. Packing does need improvement and also the quality of glass. It felt so fragile to hold and I tapped them and it sounded like they could break at the slightest touch. Another reason is the top lid pretty much covers the bottom piece almost touching the surface area where as I like the lids to have room between the surface area to make sure the parafilm seals it off but that’s more of a personal preference.

I'm an amateur mycologist looking to have reusable resources. These are ~okay~ for that purpose. I was definitely expecting something different. The glass is very clear and the dishes feel thick. Overall quality it great. However, the top lid completely covers the bottom and there is a 1/4" gap between the two. Perhaps there are different styles of dishes, with different fits? These will require lots of parafilm to seal shut! In the future, I will look for something with a tighter fit.
