ADAMAS-BETA Lab Boiling Flasks 250ml Single Neck Boiling Flasks with 24/40 Standard Taper Outer Joint

We use this type of glassware all the time, and this one works just as advertised!

Clean and clear

This flask is surprisingly solid. I love the weight. I would have liked to see a holder or stand for it because it is very much round and due to that is difficult to use unless you have a stand or make one. If you choose to get this be sure to get a stand for it.

Thicker than my glasses, and more standardized than Florida tests!Purchased these as receiver flasks for fractioning cannabis extracts after the solvent (EtOH) has been distilled out of the oil. They are thick, withstand vacuum and heat fluctuations without issue. Zero problem with the ground glass properly mating and sealing (with grease, of course.) Clips fit without fuss, or turning them into projectiles.

Very thick, and nicely shaped flask! Liked it so much i got another.
