nice glass
as expected, typical size for 3 neck. removed one star because stony lab glass doesn't accept joint clips, the joint ring is too wide. every other brand accepts the normal joint clips.

Good design, came right on time, solid build.
This flask did exactly what I needed it for, and it didn't 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.

good glass
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.

What waste of beautifuf glass Just not my day.
What waste of beautiful glass. Driver gets the main blame. Prime driver was driving his own car I'm guessing. I'm pretty sure he stopped short, causing the broken flask.Packaging was a litte haphazardly put together. Just not my day.

Matraz de 3 bocas 24/40 de vidrio de muy buen calidad, muy buen espesor. No los uso con clip para poder corroborar o no lo que dicen otros compradores. Entrega un día antes de la fecha indicada, al vendedor responde todas las preguntas muy amablemente y te da factura, evidentemente es factura extranjera para México pero sirve para mi trámite.
