Bacteriostatic Water — 20mL Multi-Use Vial

Q: What is Bacteriostatic Water used for?

Bacteriostatic Water (BAC Water) is the standard solvent for reconstituting lyophilized peptides. The 0.9% benzyl alcohol preservative inhibits microbial growth, allowing the same vial to be punctured multiple times for sequential reconstitutions over up to 28 days.

Q: How long is Bac Water stable after opening?

Once punctured, a Bacteriostatic Water vial is good for up to 28 days at room temperature thanks to the benzyl alcohol preservative. Unpunctured vials are stable at room temperature for the printed expiry (typically 24 months from manufacture).

Q: Is Bac Water the same as sterile water?

No — plain "sterile water for injection" has no preservative and must be discarded after a single use. Bacteriostatic Water contains 0.9% benzyl alcohol which prevents microbial growth in multi-use vials. For peptide reconstitution, always use Bacteriostatic Water unless your specific protocol requires preservative-free water.

Q: How do I store Bacteriostatic Water?

Store the Bacteriostatic Water vial at room temperature, protected from light. No refrigeration needed.
