Great quality and does not have the logo on the side as shown in the description. I used them to make industrial pour over coffee stands.

Product came broken. Very poorly made and packaged poorly.

The first time I ordered I bought a 250ml evap flask. I was so pleased with it that 2 days later I bought both a 100ml and 50ml flask. The flasks were well packed and made of thick glass with no imperfections that I noticed. Also, the 24/40 joints fit perfectly with the other glassware I own. I don't make many reviews, usually only on products that are I think are good for the money. In my opinion this product is good, highly recommended!

Nicely made plain distillation 3-way. Not really much to say.<br><br>Do pay attention to the quality of the cap washer though. I have seen one of these that seemed a little loose. I solve the problem by picking another one, or a little plumber's teflon tape.
