Selected User Reviews For Corning Pyrex 5640-2 2ml Class A Heavy Duty Volumetric Round Bottom Flask withCorning Pyrex Glass Standard Taper Stopper (Case of 12)
Unlike what was pictured, the product is completely different in real life. This is essentially an old fashioned test tube, which is fine, but in the description it states that it comes with a "Corning Pyrex Glass Standard Taper Stopper" - which it didn't. There was no response from the seller when I contacted them.
This works nicely.
By preparing a single batch in a 10L flask, you can get greater accuracy and perform fewer calculations than with a 1L flask. It appears that the flask is stable and sturdy. In the product picture, the flask appears to be smaller than it is in reality. The bottom is generally larger than what is pictured, similar.
I'm glad you like it!.
The best flask on the market. The piece I have in my collection is beautiful. A great value for the money I spent.
