    Very reasonable quality given the price

    I've got years of academic lab experience and have been lucky enough to get my hands on plenty of high quality chemistry labware. This flat-bottom RBF is on-par with some of the equipment that I was using during my research.No concerns about this glassware!

    Good quality basic boiling flask

    Decent thick enough walls to stand up to regular use. I continue to be impressed with StonyLab glassware.

    Just as advertised

    Wish I would if had a chance to use this bad boy. I m such a butter fingers thst I literally had this thing in my possession for less then 5 minutes before dropping and smashing it completely. I bet it would have worked great but ill never know. It would be a dope idea to offer glass insurance I cant seem to keep glass anything around for more then a couple weeks tops before breaking or dropping the damn thing.

    Different Volume

    Bought this in a pinch when a few of our lab flasks broke during washing. While they serve their purpose, I received different volume flasks(I would guess that two were 60ml and two were 50ml) . The neck and fitting did work and were 24/40 standard glassware fitting, so no issue with that and they still worked for our purposes, but something to keep in mind if you need an exact volume. One bonus I would add is that they were made solid and not cheap too fragile.
