I have a 100ml ampulla of Bbr3, it's a lot more than i need for my first usage. So what should i do once i've broken the ampulla and .withdrawn the 5ml or so that i need ? Try to reseal the ampulla with a torch, is it reasonable ? Or reseal the ampulla with some kind of wax ? If l need to take some say 20 times i don't want to break glass 20 times, the best solution would be to transfer it to a dark glass bottle, then knowing the agessivity of the product what would be the best capping ?
I'd like to be able to conserve it and use it at will for maybe one year or two. Since i have no fume hood i would operate outdoor, maybe a small fan pushing away from me the hbr fumes, double pair of gloves and googles.
Thanx for your help.

No fume hood?  sounds liike you're doing something nefarious.  It will go bad once you open it.  You will have to distill it.
