🧪 Soccerene 20-Pack 60mm Glass Petri Dishes with Lids | Tissue Culture Plate | Autoclavable Borosillicate Glass | by Soccerene Review

These are definitely not borosilicate glasses, they should hold up to a little heat but when I heated them and increased the temperature by 15 degrees F every 5 minutes they all shattered before breaking 115!

I bought these devices not realizing how small they are. Having used the 90mm cymbals I prefer the larger cymbals but they are definitely big enough for my needs. I can't drop them either, I dropped 3 and only 2 survived.

Came in individual cells, not sterile packaging, so they need to be cleaned before use. Luckily none of them were broken, but there were no breakable items on the box. Def came from China. I just wanted to warn you. Edit: The top glass is much larger than the bottom pane, so there's a big gap underneath. Even taped it to seal all my glass panels.

Only one set of cookware had a chip on both the bottom and top but I can still use it until it breaks so not bad for a set of 20 . All of them were surprisingly homogeneous and uniform in the thickness of the glass. All of the lids fit snugly on the bottom panel, and they all had about the same spacing between the edges of the panel. Slightly looser than a plastic Petri dish, but not bad. Would probably order again

I got these for a seed germination experiment and they are great for that. They sent me 20 instead of 18 and none were broken or chipped. It doesn't stand for medical use but for lab use, so I'm not sure what acid resistance is. However, I have no intention of doing such a thing. They're stronger than the 100mm models I've had before and I like the smaller footprint. Saves my desk space for something else.
