Huanyu 100mm Glass Petri Dish with Lids High Borosilicate Glass Petri Dishes Bacterial Culture Dishes for Lab Science Experiment (5pcs: 100mm)

The media could not be loaded. Thick, crystal clear, loose-fitting, and complete coverage.I am very pleased with the thickness and toughness of these glass Petri Dishes.Can put through high temp sterilization.No more disposable plastic dishes, these will last for many years/cycles to come.Absolutely worth the money, I would recommend them without any hesitation.The best Glass Petri-Dishes I've found anywhere at any price.

some were damaged upon first order but replacement was seamless. I now have a great set of plates for mushroom cultivation. These are higher quality than the first product I bought.

Perfect I’m not an expert in these but it’s definitely worth the purchase.

Great quality glass. But the tops are like a good Centimeter bigger than the bottoms. Like way bigger difference than it should be. Maybe that is normal for glass dishes? Just weird, makes them hard to handle.

It’s been a rather long time since I handled a glass Petri dish so I don’t have a good comparison handy but these do seem rather thin. However, there has to be some sort of trade-off when you’re getting 5 for not much more than the price of one.The main problem is going to be storing these in a household situation such that they won’t get broken. I cut squares of bubble wrap and put those between the dish sides and the tops. That ensures no rattling.The factory seems to be separating the tops and bottoms with only a sheet of tissue paper. It seems like a thin foam sheet or something might be a better choice.Other quality issue that usually won’t matter is that the glass is not perfectly flat, but is a little distorted as seen in the photos.If these cost any more than they do they’d be getting 3 stars but for the price I think 5 is reasonable.I doubt these are really durable enough for something like a heavily used lab or school situation. Even if everyone is always careful, they probably just won’t be able to endure as much heating, cooling, and handling as thicker glass. But around here they won’t get used constantly so should be fine for what I need.

I've ordered these twice now, soon to be thrice. Overall I'm very happy with these. The packaging has been excellent. No breakage at all. The one thing I do wish is that the lids fit better. I understand the need for air exchange and therefore the need for lose fitting lids. But the gap can be large enough that when applying parafilm I can miss a spot if I'm not careful.

Delivered in a timely fashion.Only one bottom dish broken.They don't have a close fit, so the top dish will have a decent amount of play in it when over the bottom.

Reviews for this company had me worried that the material and shipping might be sub-par. It was nothing like that. The dishes came well packed with no breakage and will fulfill the need that I have. Good job and good product.
