What is Bacteriostatic water? (Bac Water)

Bacteriostatic water (commonly shortened to Bac Water) is sterile water containing 0.9% benzyl alcohol. This preservative inhibits bacterial growth, allowing the solution to be safe for multiple withdrawals from the same vial over a 28-day period. It is the gold-standard reconstitution solution for laboratory research, particularly for reconstituting peptides and other compounds that require long-term sterility and stability.

  • Many researchers search for Bac Water at CVS, Walgreens, or other local pharmacies, but these major retailers typically do not sell 30mL multi-dose vials over the counter without a clinical prescription. Because of this, finding Bac Water near you can be difficult. We provide a reliable, U.S.-based online alternative, offering genuine Hospira® and USP-grade generic vials with same-day shipping to ensure your research stays on schedule.

 While you can find “reconstitution solutions” on Amazon, they are frequently unverified, “cosmetic-grade” liquids that do not meet USP (United States Pharmacopeia) standards. Amazon’s open marketplace often bypasses the strict climate-controlled storage and “Chain of Sterility” required for medical-grade supplies. Buying Bac Water on Amazon risks contamination or improper benzyl alcohol concentrations, which can compromise your research. We provide 100% verified, laboratory-grade supplies shipped directly from our climate-controlled U.S. facility.

Hospira (a Pfizer company) is the global leader in sterile injectable liquids. Unlike the generic brands found on Amazon, Hospira Bac Water is manufactured in FDA-registered facilities and guaranteed to contain exactly 0.9% benzyl alcohol. This precision is vital for the long-term stability of sensitive research compounds. When you choose Hospira over an unbranded Amazon alternative, you are choosing a multi-dose vial with a proven track record of clinical integrity and safety.

Because Bacteriostatic Water is a regulated medical supply, many Amazon sellers list products as “Reconstitution Solution” to avoid being delisted. These products often lack the necessary 0.9% benzyl alcohol preservative required to inhibit bacterial growth. For peptide research, using a substandard solution can lead to degraded compounds or localized infections. We only stock USP-grade Bacteriostatic Water, ensuring that your research is backed by the highest purity standards available.
