Premium Bacteriostatic Water — 30mL Multi-Use Vial

Our 30mL bacteriostatic water vial is our most popular product and the go-to choice for laboratories and research professionals who need a reliable, high-volume reconstitution solution. Each vial contains 30mL of USP-grade sterile water preserved with 0.9% benzyl alcohol — three times the volume of our 10mL format at a fraction of the per-milliliter cost.

What Is Bacteriostatic Water?

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, a preservative that prevents bacterial growth and allows the vial to be accessed multiple times without compromising the solution. This multi-use capability makes bacteriostatic water an essential supply in any research setting where repeated reconstitution or dilution is required over the course of days or weeks.

Composition & Specifications

Every 30mL vial is manufactured to exact specifications and tested before release:

  • Volume: 30mL per vial
  • Preservative: 0.9% Benzyl Alcohol (USP grade)
  • pH Range: 4.5 – 7.0
  • Sterility: Verified via membrane filtration testing
  • Endotoxin Level: Below detectable limits
  • Packaging: Clear borosilicate glass vial with rubber stopper and aluminum crimp seal

Why Choose the 30mL Vial?

The 30mL format is the preferred choice for researchers who go through bacteriostatic water regularly. The larger volume means fewer vials to open, less packaging waste, and a lower cost per milliliter compared to the 10mL option. If your lab uses bacteriostatic water on a daily or weekly basis, the 30mL vial is the most practical and economical choice.

Made in the USA — Quality Guaranteed

All of our bacteriostatic water is produced in USA-based facilities operating under current Good Manufacturing Practice (cGMP) guidelines. Every lot is tested for sterility, endotoxin levels, pH, and preservative concentration. We publish a Certificate of Analysis (COA) for each batch so you always know exactly what you are receiving. Our commitment to quality is not just a selling point — it is the foundation of our business.

Storage & Handling
