Screw cap vials to store gear

[vitormartinoavelar]

Hi guys,thats my first post here,i'm brazilian so sorry for my bad english.If this is not the right area of the forum to post it please appologise me.

I'll start homebrewing soon,have some raw sources to try,i have easy acess to those stuff.
BA
BB
Ethyl Oleate
Guaiacol
Whatman filters
etc.
My only concern is that is nearly impossible to find pre sealed sterile vials in BR,but is realy easy to get those glass screw top/cap vials (the cap comes with a rubber septum,so i don't need to unscrew open then to pull the oil from it).
I am aware of the sterilization process,so thats my doubt:
If I sterlize them properly,then put the oil inside and screw/close then tightly there is still a relevant contamination risk.
Thanks for the patience.

Most use crimp tops where they crimp the top after they fill the vial. So I would assume ur screw top would be sufficient as long as it creates a solid seal. Having pressure escape would make it hard as hell to draw out of.
