Funny thing, I don't think I ever got bacteriostatic water in a glass vial. If I did, I'd probably end up reusing it. The vial would be worth more than the contents. I've even reused the plastic ones making my own BW on the fly because it's so easy. Plus they rape you on the 30ml vials for $10+ when it's about only 12¢ worth of distilled water and benzyl alc.
