Bac water is a common abbreviation for bacteriostatic water: water formulated with a preservative to help limit bacterial growth. For wholesale buyers, the name alone does not establish a product’s grade, intended use or testing. Review the supplied label and lot-specific documentation.
Our filled products are offered for laboratory research use only, not for human or veterinary use. This guide explains purchasing considerations; it is not an injection or reconstitution protocol.
What does bacteriostatic water contain?
Benzyl alcohol is commonly used as the preservative. For context, Pfizer’s labeling for its prescription Bacteriostatic Water for Injection describes formulations containing 0.9% or 1.1% benzyl alcohol. That labeling applies to Pfizer’s products and does not establish the regulatory status, sterility or suitability of a separate research-use product. Read the manufacturer’s labeling.
Does the preservative prevent all contamination?
No. CDC guidance explains that preservatives in multidose medication vials help limit bacterial growth but do not provide complete protection from contamination and do not act against viruses. A preservative is not a substitute for appropriate handling or evidence of product testing. Read CDC’s multidose vial guidance.
Bac water, sterile water and saline: check the label
These names should not be treated as interchangeable purchasing specifications. Compare the formulation, preservative, stated grade, intended use and documentation for the exact product. Do not assume that a research solvent is suitable for a particular assay or clinical application because another product has a similar name.
How should wholesale buyers choose vial sizes and packs?
Our range includes 3 mL, 10 mL and 30 mL glass vials. We supply bac water in glass only, never plastic. Available order formats include 10, 100 and 250-vial packs, plus custom quantities.
- Listed packs: compare 3 mL and 10 mL options and current prices on BuyBacWaterUSA.com.
- 30 mL or 250-vial packs: request pricing and availability before ordering.
- Unlabeled stock: confirm label responsibilities, lot identification and packaging.
- Empty glass vials: specify the volume, closure, quantity and preparation requirements separately from filled bac water.

What should you check on a Certificate of Analysis?
Match the report to the lot, sample and tests stated. Our published report for a 10 mL sample from lot H1001A shows benzyl alcohol content of 0.92% and pH of 6.46. Those results do not establish sterility or endotoxin testing, and cannot be generalized to every lot.

What about storage and expiration?
Follow the actual product label, supplier documentation and your laboratory’s procedures. Do not apply a universal unopened shelf life or post-opening expiry to every bac water product. CDC’s 28-day guidance concerns opened multidose medication vials and allows different manufacturer instructions; it is not proof of stability for a separate research-use product.
