Polystyrene Petri Dish 35 x 12mm, Sterile, Pack of 10, Plastic Petri Dishes with Lids,Mycology Supplies agar Plates- Perfect for Cultivating Microbes

I picked these up for the high school level labs of my home schooled student. The price was good in comparison to others, and the quality is just fine. They are definitely good enough for what we do, and if I need more, I'll be purchasing these again.

So many negative reviews about these being small but as someone who looked at size BEFORE buying these are exactly what I wanted. I was looking for a small clear dish to use to feed shrimp in my aquarium and these are small enough that they don't overpower my tank. Obviously not what they're intended for but the SMALL size is just what I wanted.

Really poorly made, the the lids don’t fit right!

One was cracked and one broken upon delivery. I understand they are cheap but would be nice to have all 10 in working condition.

These did come super sterile and I have had no problem with contamination.

Great price for petri dishes for my daughter's science project. As described.

They were not expected to be so little, about the size of a 50cent piece. Still worked for what I needed them for

You'll definitely want to check the dimensions before ordering. These are TINY!They came in a very loose, non-airtight bag, so I'm not sure how they could have been sterile. You would probably want to look elsewhere if you need sterile dishes.The lids on these were a couple millimeters bigger than the bottoms, so I had to take care to pick up the lid and the dish separately each time I handled them. The overlapping lid touched the table surface separately from the bottom, so I felt like that was a major potential for cross-contamination.There is a huge possibility for air flow and other contaminants through these, so I don't think these are well-suited to any type of important laboratory procedure.
