Published by Bacteriostatic Water Lab — your trusted source for authentic, lab-tested bacteriostatic water, including genuine Hospira brand products.
Bacteriostatic water is one of the most commonly counterfeited products in the research supply market. With demand rising and legitimate supply sometimes limited, unverified sellers have flooded the market with mislabeled or improperly manufactured products. This guide explains what genuine bacteriostatic water is, how to verify authenticity, and what sets a legitimate supplier apart.
What Is Bacteriostatic Water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which acts as a preservative that inhibits bacterial growth. This allows a single vial to be safely used for multiple withdrawals over a period of up to 28 days, unlike plain sterile water which must be discarded after a single use.
It is manufactured under strict pharmaceutical standards and is used widely in laboratory and research settings for reconstituting compounds.
The Problem: Counterfeit and Mislabeled Bac Water
Not all products sold online as “bacteriostatic water” meet pharmaceutical standards. Common problems in the market include:
- Plain sterile water relabeled as bacteriostatic water (no benzyl alcohol preservative)
- Improper benzyl alcohol concentration — too little fails to preserve, too much can interfere with research compounds
- Non-sterile manufacturing conditions leading to contamination
- Counterfeit branding — vials falsely labeled as Hospira or other pharmaceutical brands
How to Verify Genuine Bacteriostatic Water
Before purchasing from any supplier, check for the following:
1. Lot Numbers and Expiration Dates
Every genuine vial carries a printed lot number and expiration date. At Bacteriostatic Water Lab, every product we sell displays its lot number, and these can be cross-referenced with manufacturer records.
2. Manufacturer Traceability
Genuine Hospira bacteriostatic water (Hospira is a Pfizer company) is produced in FDA-registered facilities. Authentic product can be traced back through the supply chain. We source our Hospira brand bacteriostatic water through verified distribution channels.
3. Correct Labeling
Authentic bacteriostatic water labels always specify:
- “Bacteriostatic Water for Injection, USP”
- “0.9% Benzyl Alcohol added as preservative”
- Manufacturer name and address
- Lot number and expiration date
4. Proper Packaging
Genuine vials arrive sealed with intact flip-top caps and crimped aluminum seals. Any vial with a damaged or missing seal should never be used.
