Pyrex 1003-250CN Heavy Duty Griffin 1003 250mL Beaker Double Scale Grad, Glass

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.

Another quality mixer

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.

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.

Quality sturdy glass.

I bought this little beaker for my bar cart. 250ml= 8.45 oz. I use it to hold spring water to add to my Bourbon or Scotch. It works perfect.

It's beautiful. I love lab beakers. Going to put it with my older small beakers.

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%.

Ive used it once to heat cocoa butter and other oils for a skincare cream. It maintains the heat well and cleans up easily.

Heavy duty & absolutely awesome!! I wanted it to make homemade lip balm & I can even hold the top area to pour the balm because it isn't even hot!! I ordered cheaper ones from another company & they arrived broken & the company wants me to mail them back to China & then they will refund my $!!! The postage would be MORE than what I paid for them!! Best to offer better quality to begin with!

This is the best quality beaker I've come across in a long time. The measurements are accurate as confirmed by weight of water, and the glass is very thick. The pour spout seems to get a nice fine stream and easy to pour, too.

Exactly what I needed! I have been searching far and wide for glass that isn’t too thin and won’t explode on me. I use it for pouring my hot coffee or espresso into for mixing. Love it.

Works well can take the heat no issues
