Bluejay Bio 65mm Petri Dishes Sets of 10 and 20 with Gridlines for Accurate Colony Counts - Medical Grade Polystyrene for Sterile Cultures - Perfect for Storing Small Items (10 Pack)

They worked fine for the most part it’s just that the quality of the dishes weren’t what I expected. They were rather fragile and they loosely fit to each other si in order to truely have a see I either had to glue them closed or put many layers of tape.

Don’t expect all 10 to be intact when you order. 2 pieces were broken on arrival.Picture included, it is the 2 pieces at the bottom of the picture.

I used these to perform an experiment of different cleaning supplies effectiveness. They all arrived in good condition (no cracks or breaks). Worked perfectly for what I needed. (If you are curious about my results, the best cleaners of what I tested were Great Value anitbacterial wipes, Thieves essential oil, Dawn, and Hydrogen peroxide).

We got these for a science fair experiment and they did their job perfectly.

Unfortunately I received a pack that included a broken dish. It is too late as I need to use them today.

Literally every lid was broken, and 2 of the petri dishes were broken as well.

Ok, I'm not happy, but 1 star feels harsh for the nice concept of the lined dishes for easy measuring. I'll go with 3 stars Bc MOST of the dishes were not cracked, but one was cracked nearly in half and at least 2 others had small cracks when I looked at them closer.*edit to addI never heard anything from the company, but I left on vacation and when I arrived home I had a new set of these waiting on me. I'm happy to report none of them are cracked, so I'm updating this review to 5 stars and I am giving them the benefit of the doubt that the original set was a fluke, but in case they are checking this I would add that communication is always appreciated and many times it's plenty ;)

Did not survive autoclave.
