The Essential Reconstitution Solution

Bacteriostatic Water for Injection, USP is a sterile, non-pyrogenic preparation of purified water containing 0.9% (9 mg/mL) benzyl alcohol as a bacteriostatic preservative. This multi-dose solution is the gold standard for reconstituting lyophilized peptides, enabling safe, repeated withdrawals while maintaining sterility for up to 28 days after initial use.

The benzyl alcohol preservative inhibits bacterial growth without killing existing microorganisms, providing extended protection that sterile water alone cannot offer—making it indispensable for research protocols requiring multiple doses from a single reconstituted vial.

Why Bacteriostatic Water?

The choice of reconstitution solution directly impacts peptide stability and experimental integrity:

Note: Bacteriostatic saline is not recommended for peptides in acetate salt form, as sodium chloride may cause precipitation.

Key Features

• Sterile & Non-Pyrogenic — Meets USP standards
• 0.9% Benzyl Alcohol — Optimal concentration for bacterial inhibition without peptide interference
• Multi-Dose Capability — Repeated withdrawals from a single vial for up to 28 days
• pH Balanced — Typical pH of 5.7 (range 4.5–7.0) compatible with most peptides
• Peptide-Safe — Does not interfere with peptide structure or biological activity
• Naturally Derived Preservative — Benzyl alcohol occurs naturally in fruits and tea

Proper Use Guidelines

Storage After Reconstitution:

• Store reconstituted peptides at 2–8°C (refrigerated)
• Protect from light
• Use within 28 days of first puncture
• Never freeze reconstituted solutions
