Bac water usage and waste

[lerig]

I usually use about 2ml of bac water for my peptides. As far as I know, bac water only lasts about 30 days once the vial is opened. Since the water that ships with the peptides is usually just 1ml, I kind of need to use vials, but I feel like I'm throwing away 8ml every month. How do you guys handle it? Bac water isn't that expensive, so it's not that deep, but I am still wondering...

I guess getting ampoules is the correct answer but I can't really find those

Hello.

You can keep and use beyond 30 days. Maybe not 6 months of courseMaybe not 6 months either of course
If it's well preserved in the fridge and that each use is a sterile process.
