Sterile Plastic Petri Dishes Set, 50 Pcs Blank Microscope Slides, 100 Pcs 20x20mm Square Cover Glass, 5 Pcs 90mm Diax15mm Deep Lab Petri Plate Dish with Lid and 10 Test Pipette Droppers

I used these for Halloween treats. They were super easy to use. The size was perfect and they were a great value. They were a better quality than I thought they were going to be

I needed something cheap and reusable. This works perfect for little dishes. They hold water/food super easily.

not fully sterile, but not an issue, all is there and as described.

Necessary for viable observation on the microscope and at the current price you can't beat it.

I have tried a couple Petri dish suppliers, but this is one of the few that actually arrived without any damage and the sterile bags were sealed well. Highly recommend these dishes! I bought them for use in mycology and growing mushrooms

They are very thin and cheap. One was completely crushed.

Science teacher I bought these for liked them

At about 60 cents per dish these are a good deal. Far cheaper than standard glass or borosilicate (pyrex). For various experiments growing culture on agar these are fine. Don't even think about trying to reuse them. There's no way to sterilize these thin plastic dishes. But... you know... 60 cents.
