Single Neck Flat Bottom Flask, 24/40 Joint, 50-5000 ml

I LOVE this flask, it is so versatile I use it for everything! It is thick, it seals tight and despite how much I have abused it, it does not have a chip on it! It even survived being used for boiling a solution and then dunked into liquid nitrogen without a cool down period.

Great Halloween prop, which subsequently broke on the one day of use.

Wish I would of 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.

Have only used this as a receiving flask and have not heated it yet but I have no doubt it will be fine for that. Thick glass and no blemishes. Stony lab seems to be some of the better quality glassware in Amazon. Shipping was fast for this item as well.

I used this flat bottomed flask in a evaporation experiment using a magnetic spin bar coupled with a standard evaporator which I also bought from Laboy to include a 30 degree neck. I was skeptical about the ability of the flask to deal with quenching water once the molten mass had reacted but it performed flawlessly. Recovery of the water from the solution was 99.4% via the condenser tube. I have used Laboy glassware seldom in the past but am convinced now that the future use will be exclusive in our labs.
