ULAB Scientific Glass Erlenmeyer Flask Set, 5 Sizes 50ml 150ml 250ml 500ml 1000ml, 3.3 Boro with Printed Graduation, UEF1002

I'm a biologist but I purchased these to help our kid's science project and they have been used for two years now for various at home projects from simple chemistry and biology to working on an ongoing water sample study our kid has gotten involved with. Absolutely worth it, solid product.

I've been making beer brewing starters for a few months with these now, and haven't had a problem dumping boiling water in them and then cooling them down quickly. I haven't boiled in flask yet, but especially for the price these are great.

I liked that this erlynmeyer is light and pouring is just great.

Item arrived quickly and in great condition. I love that it came with a stir bar.

As expected

Haven't used it yet since the event I bought it for (IVF baby shower) hasn't come yet but its exactly what I was looking for to use a vases for flowers.

Structural integrity is decentVolumetric accuracy is terribleGood for storing, or letting emulsions separate and remove top layer. That’s about it.

super assortment for homebrewing

I can’t comment on the use of these as genuine scientific glassware as I bought them for the express purpose of displaying two of my passions; science (especially chemistry) and gaming.Other options may be available, but the range of sizes are ideal, allowing display of different items (so far spare meeples, dice and Lego mini figures). My only minor disappointment was that they didn’t come with bungs, which I had to order elsewhere.

The arrived quickly and were as described. My girlfriend was using them to make her own face creams. They take the heat from that fine. The only thing is very difficult to clean because of the shape. But that’s really more of our problem. Recommended.

Muy buen material, altamente resistente.

Perfect for my brewing applications and fancy drinks style! Product was in mint condition!
