BAC Water 3mL

Premium bacteriostatic water (agua bacteriostática) for laboratory and research use in Colombia. Sterile-filtered, independently tested, and packaged in sealed 3mL glass vials using USP-grade materials.

BACColombia provides laboratory-grade bacteriostatic water manufactured under controlled conditions with 0.9% benzyl alcohol (USP standard), 0.22μm sterile membrane filtration, and independent third-party quality verification for every production batch.

The 3mL format is our compact presentation — ideal for smaller-volume laboratory applications, single-use workflows, or customers who prefer individual-sized vials for precise inventory management.

• 0.9% Benzyl Alcohol (USP Standard)
• Third-party laboratory tested (COA available per lot)
• 0.22μm sterile membrane filtration
• Lot-number traceability for every batch
• Sterile sealed 3mL glass vial
• Nationwide fulfillment across Colombia

What Is Bacteriostatic Water?

Bacteriostatic water (agua bacteriostática) is sterile purified water that contains 0.9% benzyl alcohol as a bacteriostatic preservative agent. It is also referred to as BAC water or BWFI (Bacteriostatic Water for Injection) in laboratory and scientific contexts.

The benzyl alcohol inhibits bacterial growth within the water, allowing for repeated vial access under aseptic laboratory handling conditions — unlike standard sterile water (WFI), which must be discarded after a single use.

Bacteriostatic water is widely used in research laboratories, peptide reconstitution workflows, compounding environments, and scientific applications where preservative-supported sterile water is required.

Why Choose the 3mL Format?

The 3mL vial is designed for laboratory applications where smaller volumes are preferred or where single-use handling is standard practice.

• Compact and portable — minimal storage footprint for space-constrained environments
• Single-use friendly — ideal for workflows where one vial per application is preferred
• Precise inventory control — easier to track consumption at the individual vial level
• Lower entry price — accessible starting point for new customers or trial use
• Same quality standards — identical filtration, testing, and packaging as all BACColombia products

For higher-volume needs, our 10mL BAC water vial offers better per-milliliter value.

Why BACColombia?

Most bacteriostatic water sold in Colombia is sourced as an afterthought by supplement or peptide retailers — with little transparency regarding filtration methods, preservative concentration, or independent testing.

BACColombia was built specifically to provide a higher standard of bacteriostatic water in Colombia:

• Independent third-party testing for every production batch
• Certificate of Analysis (COA) available by lot number on request
• USP-grade materials used throughout production
• Full lot-number traceability from production to delivery
• Professional packaging in sealed glass vials with aluminum flip-top closures
• Dedicated focus — we specialize in laboratory-grade sterile water, not supplements or retail accessories

Independent Quality Testing

Every BACColombia production batch undergoes independent laboratory analysis before release. Testing includes:

• Endotoxin screening (LAL method)
• pH verification
• Sterility validation
• Visual purity and particulate inspection
• Benzyl alcohol concentration verification
• Batch-to-batch consistency analysis

Product Specifications

Storage & Handling

• Store at controlled room temperature (15–25°C / 59–77°F)
• Protect from direct sunlight and excessive heat
• Keep vial sealed until ready for use
• Do not freeze
• Visually inspect for particulates or discoloration before each use
• Discard if seal is broken, compromised, or if contamination is suspected

Frequently Asked Questions

What is bacteriostatic water used for?

Bacteriostatic water is used in laboratory and research environments that require sterile purified water with a preservative agent. Common applications include peptide reconstitution, reagent preparation, and other laboratory workflows requiring multi-access sterile water.

What does “bacteriostatic” mean?

Bacteriostatic means “inhibiting bacterial growth.” In the context of BAC water, the 0.9% benzyl alcohol acts as a preservative that prevents bacterial proliferation within the water after the vial is accessed.

What is the difference between bacteriostatic water and sterile water?

Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, which allows for repeated vial access under aseptic conditions. Standard sterile water (WFI — Water for Injection) contains no preservative and is intended for single use only.

Is BACColombia bacteriostatic water sterile?

Yes. All BACColombia bacteriostatic water undergoes 0.22μm sterile membrane filtration and is independently tested for sterility verification before release.

Do you provide Certificates of Analysis (COA)?

Yes. COA documentation is available upon request by referencing the lot number printed on your vial. Contact us through our contact page with your lot number.

How should I store BAC water?

Store at controlled room temperature (15–25°C), protected from direct light and excessive heat. Do not freeze. Always inspect the vial visually before use.

Do you ship nationwide in Colombia?

Yes. BACColombia fulfills orders to all major cities and regions across Colombia, including Bogotá, Medellín, Cali, Barranquilla, Cartagena, Bucaramanga, and more.

What is the difference between the 3mL and 10mL vials?

Both formats use identical production methods, materials, and quality testing. The only difference is volume. The 3mL vial is suited for smaller-volume or single-use applications. The 10mL vial offers better per-milliliter value and is preferred for routine laboratory use.
