United Scientific™ Borosilicate Glass Beaker, 1000ml, Autoclavable, 1 Each | Chemistry Glassware, Low Form Griffin Design, Molded Pour Spout, ASTM-E960 Compliant, Double Scale Graduated

I studied science in college and took a lot of chemistry. I just received my 1000mL beaker and I'm very happy with it. It's just as thick and sturdy as I remember the beakers being in my college labs. I'll be using this for skincare formulations--it will be heated to about 160 degrees Fahrenheit regularly. If I have a problem, I'll update, but I don't anticipate having any issues. The glass is thick and the beaker arrived without a flaw. You do have to be careful when selecting beakers because there is a ton of thin-walled and very fragile glassware on the marketplace. You can't go wrong with this brand, however. This is my second beaker from United Scientific and both have arrived unblemished and of a similar sturdiness. I'm glad to have found it so I don't have to save for the much pricier Corning PYREX glassware. I feel this is of similar quality and an excellent value. These are made in India. Now, I have seen a LOT of reviews of beakers lately and I just have to say this: beakers are NOT measuring devices. The markings on the side of a beaker are approximate. If you want or need precision you MUST measure using either weight (a scale) or a graduated cylinder which measures volume. These are the tools you use to measure in science--not beakers. So quite posting that your beakers aren't accurate. They aren't meant to be. I don't know why--I just know that's the way it is. If you intend to mix things inside a beaker, you should probably get one much larger than the volume you intend to mix--because the stated volume is usually to the top.

Appear to be pretty good. Used for sourdough starter. Previous broke when stirred vigorously. Will update this if these break.

Great quality, good packing

This is the second beaker I have purchased from this seller. I make bath and skin products and this holds up so well melting butters in a double boiler. I will purchase again if I need more. The size is great for larger batches.

If amazon is your only option and you need something ASAP these are definitely going to work. Can withstand heat and I have had them last for up to a year of fairly standard lab work before noticing them deteriorating. That said they are expensive and I have been able to source thicker and far less expensive per piece options when ordered from trusted vendors outside the US.

Works good

Good quality beaker.

Good thickness. I use it to melt soy wax. It works great. Good price. Good quality glass not thin. I definitely recommend.

Lip on beaker is small and can be messy at times when pouring. Great product. No issues

se ve como en la foto, parece buena calidad

Exactly what I was looking for. If I am ever in need of another I will certainly buy again.
