Selected User Reviews For Thomas 7453 Petri Dish, Stackable, Sterile, Bulk, 100 x 15 mm Size (Pack of 500)
I highly recommend this product
What I liked
The sleeves of the sweater were smooth and matte in texture. The packaging kept a column of information organized and still made it easy to reach for it whenever I needed. Those I disliked Compared to other dishes I have used, the dishes were a bit thinner. Compared with others that I have used, the gap between the lid and the base was wider. It was difficult to wrap it in parafilm as a result. The arrival of several dishes was accompanied by a number of broken dishes.

We could have gotten a second star but we had some broken dishes
The sleeves were received with multiple damaged plates and most of the breaks were towards the middle. However, it wasn't enough for me to worry about it, because I still got a lot out of it. As of now, all plates that have been poured have been clean. The mushroom cultures are grown with this medium.

It takes me about a week to order a case
The quality is excellent. They are great quality dishes, the plastic is very strong and the sleeves are thick. By doing this I can pour the agar while it is still quite hot without worrying about it Besides being sterile, they also require no sterilization. Considering that these sleeves are made of thick plastic, they protect your dishes quite My experience with this company is that I have never seen a torn sleeve. The only thing that keeps me from giving it a 5 star is that there is a broken or missing dish every few sleeves. I am hard to please when it comes to giving out five stars. I've never ordered a set of petri dishes without getting that as well. So long as the price stays around where it is, I will not switch suppliers as long as the bad dish rate is low. Even at 18 cents per dish, getting some broken dishes in an order can add up to a reasonable amount of money (like a buck or two). With the supplier able to raise the price per case about a dollar, and eliminate broken dishes with an additional dollar of packing, the outcome would probably be a neutral win/loss for both the seller and the consumer, but the consumer would probably be a little better off. It is definitely recommended that you try.

You will be 100% satisfied with your purchase
You should check these out. It was the perfect price. None of the items Unlike the sleeves, which are made of thin plastic, the sleeves are thick. There are 20 sleeves in a pack. We will buy from them This time again. In 500 groups of 500, not a single one 5 stars

My only wish is that I had found this My only wish is that I had come across these earlier
It's my job to raise mushrooms in Petri dishes, so I go through a lot of them. There is a great deal of value in these. It's true that they're a little thinner than what I'm used to, but they just do the job and at that price they can't be beat.

This is the best bang for your buck (no doubt about it)
On the one hand, I was a bit worried about the quality and on the other hand I worried about receiving broken dishes (based on other reviews), but I was happily surprised. Even though they aren't the most sturdy petri dishes to be found on the market, I still think they are a lot better than I expected. But what was even better was the packaging. The plates weren't broken and they were wrapped nicely too (25 per envelope), which I think to be sterile. I'm honestly not just interested in how long they last, but rather how economical they are, so even one use is enough for me to keep buying them.

The best value for your money
It is impeccable. Having previously ordered from another online retailer and receiving plates w/cracked and splintered lids, I contacted E-Z Foods. This is a superior product, in my opinion. I really like the packaging, and it is a good value. -We even like the plastic sleeves that seal each stack of 25 plates. When you have other work to do or just want some more contamination protection, you can easily slip back on a poured tower.

The rest of the story is fine. Package seemed to be in good condition. They are sealed in thick plastic, but on checking them I find that there are two Petris smashed in at the bottom of each sleeve. Due to the weight of that side of the box or something, the losses are all on one end of the box. Otherwise, it seems to be going well. My plans for tonight are to work on them with Agar, so I will decide whether or not I will repurchase. A bit frustrating that the 12+ are broken, but a great bulk deal nonetheless.
