MED PRIDE Sterile Disposable Stackable 90mm X 15mm Petri Dishes with Lids, Clear Polystyrene Lab Plates for Science, Biology, Microbiology Experiments (25)

These are as described, and all seemed to be sterile. They’re not flimsy and are nice to work with. But they are disposable/cannot be resterilized.

Made agar dishes out of them and all were sterile. No growth except what I wanted. Still good a couple months later.

I like the price point. These do what I need. Unfortunately there is always at least 1 broken dishes. No big deal but, after awhile it adds up. I never reached out to supplier because it seems petty. This is just an honest review of the product. I will still purchase again.

Works great

out of 25 trays, (4) were not broken!!!! WOW!!!!

I mean, no lies. They are. They grow weird stuff. What fun.

As expected.

Bought these as a gift for a young boy who got his first microscope and wanted to "collect samples" around his yard of various things (soil, water, leaves, etc.) to view under his microscope. These are fairly thin, since they're not exactly made for children. However, the young boy using them is very gentle and takes care of his things, so that isn't a problem for them. The clarity and size are perfect for viewing and collecting. I'm sure if he gets older and wants to get more involved in the science, he can use these more as intended.
