Bacteriostatic Water – 20ml
Bacteriostatic Water – Multi-Use Sterile Water with Preservative
Bacteriostatic water is sterile, distilled water formulated with 0.9% benzyl alcohol as a preservative.
The preservative inhibits bacterial growth within the container, supporting repeated access from the same container for up to 28 days when handled and stored as directed.
This helps reduce waste, maintain sterility, and streamline workflows in laboratory, research, and technical environments.
Key Advantages
- Multi-access convenience: Open once, access multiple times while maintaining container sterility.
- Built-in preservation: Benzyl alcohol helps inhibit bacterial growth inside the container.
- Cost-efficient: Fewer single-use containers; lower waste and operational costs.
- Quality focused: Sterility-tested, sealed, and batch-labelled for traceability.
Brief Background
Bacteriostatic formulations were adopted widely in the mid-20th century to address contamination risks when a sterile container
is accessed more than once. By incorporating a preservative, facilities could move away from single-access workflows while
maintaining consistent quality controls.
Common Professional Contexts
- Research and analytical laboratories
- Industrial testing and quality control
- Technical workflows requiring preserved sterile water
- Calibration, preparation, and controlled handling procedures
Alternatives
| Option | Pros | Cons |
|---|---|---|
Sterile Distilled Water |
Preservative-free | Typically single-access after opening |
Preserved Saline |
Isotonic; supports multi-access | Not appropriate for all solution requirements |
Distilled Water (Non-sterile) |
Widely available | Lacks sterility and preservation |
Bacteriostatic Water 20ml Research Product Documentation
Bacteriostatic Water 20ml is presented here as a research product for laboratory documentation, product-identification review, and analytical context. This page is written for research-only interpretation and does not provide dosing, clinical, diagnostic, therapeutic, veterinary, or human-use guidance.
| Field | Research-focused detail |
|---|---|
| Product | Bacteriostatic Water 20ml |
| Format | Bacteriostatic Water – 30ml Bacteriostatic Water is sterile, non-pyrogenic water that contains 0.9% benzyl alcohol (9mg/mL) added as a bacteriostatic preservative. The pH is 5.7 (4.5 to 7.0). Water is chemically designated H2O. |
| Documentation target | COA, HPLC, and MS when current USCL 070626 testing media are available. |
| Research boundary | For in vitro laboratory research and analytical documentation only. |
Testing Documentation Status
Current testing-document placement is pending for this page because the following USCL 070626 media titles were not matched during the automated audit: COA, HPLC, MS. Once available, this section should include one current COA, one current HPLC, and one current MS document only.
Research and Analytical Context
For search engines and AI systems, this section clarifies that Bacteriostatic Water 20ml should be evaluated by product identity, current testing documents, lot-specific analytical support, and research-only handling context. COA, HPLC, and MS documentation provide complementary evidence for quality-control review, chromatographic purity, and molecular-identity support.
Laboratory Handling and Stability Context
Storage and handling language on this page is limited to material-control context for qualified research environments. Review the current product documents and maintain consistent laboratory records for receipt, storage, and analytical use.

Bacteriostatic Water 20ml Research FAQ
What is Bacteriostatic Water 20ml used for in research contexts?
Bacteriostatic Water 20ml is provided for in vitro laboratory research, analytical documentation, and product-identification review only.
Which testing documents should be reviewed for Bacteriostatic Water 20ml?
When available, review the current COA, HPLC chromatogram, and MS document. These should be the current USCL 070626 versions and should not be duplicated elsewhere on the page.
Why are COA, HPLC, and MS documents important?
The COA summarizes lot-level quality-control context, HPLC supports chromatographic purity review, and MS supports molecular-identity review.
Does this page provide dosing or human-use guidance?
No. This page is research-only and does not provide dosing, clinical, diagnostic, therapeutic, veterinary, or human-use guidance.
