Was told by an actual chemist that if you have torn that metal seal the vacuum is gone and the sterility of the vial can't be guaranteed, so it's ruined if you are an overly safe person.
You could filter it into a new vial quickly maybe, then reheat to kill bacteria or germs. That being said any money you "saved" by going this route is gone now, especially since the top was already compromised it sounds like, and youll need to buy filters, and new vials, and put in some work.
I only open this to the first edge then I fold back that metal ring and just leave it on there forever all goofy like to maintain that seal
