Works, Good Quality
The glass is great quality and thickness. Can be heated, cleaned, and used extensively. I use it for my home chemistry lab but it’s the same quality as the ones at University.

High quality
Recommended. Heavy duty beaker as described. I use it daily, and it takes boiling temps as it should. The glass is thick, and appears uniform on the sides and bottom. Screen printed text is durable. No issues. I would buy this brand again.

A true #1003 heavy duty Pyrex beaker made in Germany
After a lot of struggles trying to find heavy duty Pyrex beakers in the sizes I needed, I finally succeeded. This one was listed as a 250 ml, however the measurement markings only go up to 200 ml. So be aware of ordering a slightly larger size if the full 250 ml measurement markings are important to you. I was happy to find that these beakers were made in Germany, which another reviewer had stated makes the very best quality Pyrex beakers. Not sure if this is true, but if it is, "Made in Germany" is printed right under the word Pyrex on the side of the beaker. It is a thrill to use this beaker and not need to worry about it breaking easily like some inexpensive, paper-thin types.

Excellent and Accurate
Some of the other beakers got negative reviews due to the thinness of the glass, but this beaker is true thick Pyrex, and will withstand slight concussions with other glasses, cups, or countertops. But the best part for me is the accuracy of the markings. I put the beaker on a scale and poured in exactly 100 g of water, and the water level came up to spot on the 100 ml line. None of the other products I purchased were this accurate.

Truely heavy duty...
Heavy duty as advertised. Just wish the heavy duty was available in the tall forms. I use beakers daily...and Pyrex is hands down the best.

Good quality, functionality and design (efficacy), value
I read Question/Answers and found an excellent tip indicating that "If the product is labeled in upper case letters (PYREX), it is heavy duty geuine, made in Germany borosilicate glass. I like it but It's a bit smaller than expected-- 200 mL + 5%.
