Don't go crazy with the heat differentials, and don't toss on the ground. Other than that, if you accidentally knock it against something r have to use a torch on a seized stopper don't worry about it fracturing.

Came quickly and packed very nicely and even more secure. Seems okay no flaws in the glass. I have yet to put it to heat for distillation, so I may be updating. Other than that all is well, great price for a rbf.

I was expecting the flask to be a bit bigger like my old broken one. However, it turned out to be about 100 ml smaller so if you pour 1000 ml into the flask and want to boil it it might boil over. This product is good quality and was well packed but I can't really boil more than 900 ml in it even though it holds 1000 ml just fine.

I’ve purchased 3 flasks and a separatory funnel and all 3 broke meanwhile I have 4 year old boiling flasks perfectly in tact. As receiving flask’s they’re fine (so is are wine bottles)The flasks only broke after boiling in them and the stopcock exploded on the funnel.
