Lol I'm concerned because multi-dose vials are considered to be unsterile by the EU. IF you think about it, everytime you stick the needle in, you are potentially introducing more bacteria into the vial. Also consider the fact that when drawing oil outside air usually goes into the vial to replace it
you think youre gonna die from some bacteria IN THE AIR?
lol
also what do you think the benzyl alcohol in your gear is for...
i have some 100ml vials and some of them are 2 years old and i still use them now and then
and i never even swabbed the top once
