Bac Water (Bacteriostatic Water), 30 mL

Sterile water with 0.9% benzyl alcohol added, which keeps an opened vial usable for about 28 days instead of hours. "Bac water" is just the everyday short name for it — same product.

• 30 mL
• Preserved
• ~28 days open

Why you’d want it: The default choice for mixing any multi-dose vial. If you only buy one water, buy this one.

Picking tip: Check the label says 0.9% benzyl alcohol and the cap is sealed. In the US the pharmacy name you'll see is Hospira; in Canada, the UK and Australia it's mostly sold as “reconstitution solution” — the same thing, so go by the percentage, not the name. 30 mL is only better value if you'll use it inside the 28 days.
