This flask did exactly what I needed it for, and it did not break under the around 400��c I needed to distill mercury. Furthermore, it did withstand the boiling mercury which I was slightly worried about. All in all, a worth buy and I would recommend it to anyone who needs a 500mL 3 neck.
The bottle I received looks strong enough with clear glass. I have not started using it but will give an update after I use it
the wall is too thick for us to run our experiments
They work great and good quality.
This is good quality glass. Just note that it uses a angular interface bulge ground glass joint, not the arc bulge joint that most other companies use, and needs a different keck clamp.
