BAC Water 10mL

Bacteriostatic Water 30mL — Sterile Research Grade

Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. This preservative inhibits bacterial growth, allowing the same vial to be used for multiple withdrawals over a 28-day period — unlike sterile water for injection, which must be discarded after a single use.

Why Bacteriostatic Water

Lyophilized (freeze-dried) peptides require reconstitution with an appropriate solvent before use in research applications. Bacteriostatic water is the standard choice because the benzyl alcohol preservative maintains sterility across multiple needle punctures, which is essential for multi-dose research protocols. The 0.9% concentration is sufficient for antimicrobial activity without interfering with peptide stability or biological activity.

Usage Guidelines

• Swab vial septum with alcohol before each withdrawal
• Use within 28 days of first puncture
• Store at room temperature before opening; refrigerate after first use
• Compatible with all lyophilized peptide research compounds
