Questions & Answers

Does the company have a logo or branding?

Thank you for your interest in the Erlenmeyer flask with blue screw cap. I have not placed a logo or branding on it.

Are they heatable over flame, otherwise, with what kind of heat source can they be heated?

As far as I can tell, yes. Chem labs are full of them, which is why you see them there. There's a note on the cap about how much heat it (the cap) can handle. Standard precautions should be followed.

What is the inside diameter of the opening of the 500 ml version? It would be great if they were rubber stoppers. ?

Please be aware that the inner diameter of the opening is approximately 30 mm (1. For your convenience, we have provided 18'') Thank you for taking the time to read this.

I am absolutely delighted with this product! The lid is a great addition to the product
5/5

Purchasing these for a friend who uses them to develop the latest batch of DMT was a great experience for me. These beakers are a big hit with him!.

This seals airtight, but not completely
5/5

This product is perfect for applications where sterility is not required. For long-term storage, you might want to plastic wrap the lid and neck of the container if you're going to microwave it. Its lid did not completely seal, so if you have any media you need to boil in the microwave, it would be ideal. You can tell quality by the glass.

It's a very good quality product For our niece, who is interested in science, we used it to make a cocoa making kit
5/5

It never came in the other two sizes This film leaves me very disappointed after seeing its quality. There are pieces of glass in there It is not made of We found that 500 ml was the perfect amount of cocoa for our needs.

There is a leak of gas
4/5

The first pair is good for brewing starter and holds up to heat changes, but the second pair leaks when shut off. The good news is that I don't have to worry about glass exploding in my case. Although they may be airtight, I do not think they are.

The cost is low, the quality is not great, but it is effective
3/5

The glasses are not created with borosilicate glass of the scientific type. The flasks are very thick, much thicker than the others I have in my collection of Erlenmeyer flasks. They seem to be regular glass. these seem to work well as long as you don't switch over from hot to cold too quickly. When it went from cold to hot and hot to cold, two of the pieces of my body broke. The financial benefit is that I can just use my "real" ones for such activities, and I can use these for what they primarily serve.

I am very satisfied with this purchase
5/5

We loved these and used them to hold our adult orange crush beverages with our mad scientist costumes. A screw was included on top, which I thought was very thoughtful.

had originally planned to get the smaller version, but now that I own these, I'm glad I have the larger.
