Bac Water
A preserved aqueous diluent for controlled laboratory research workflows
- Fulfillment Origin
- us
Bacteriostatic Water is purified sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The preservative inhibits bacterial proliferation and supports repeated laboratory withdrawals when validated aseptic technique, container controls and the manufacturer's in-use instructions are followed. This 3 mL product is supplied strictly as a Research Use Only laboratory reagent and is not intended for human or veterinary consumption, administration, diagnosis or treatment.

Not for human or veterinary use. For in-vitro laboratory research only. This product is not intended to diagnose, treat, cure, or prevent any disease.
Purified water. 0.9% benzyl alcohol. One controlled laboratory diluent.
This product is a formulated solution rather than a peptide or a single chemical entity. Water is the vehicle, while benzyl alcohol is present at 9 mg/mL as a bacteriostatic preservative.
Purified sterile water
The aqueous phase serves as the laboratory solvent and dilution medium.
0.9% benzyl alcohol
Equivalent to 9 mg/mL; a 3 mL nominal fill contains approximately 27 mg when filled at the labeled concentration.
Research-use diluent
A laboratory supply, not a peptide, active pharmaceutical ingredient or finished therapeutic product.
A two-component preserved aqueous system
The formulation contains water and benzyl alcohol; it does not have one combined molecular formula or molecular weight. Any visual representation is schematic and should not be interpreted as a new molecular entity.
Formulation characteristics at a glance.
The values below describe the labeled formulation and its laboratory function. They are not clinical-performance measurements.
Compact laboratory format
Nominal vial volume selected for this product variation.
Benzyl alcohol concentration
Equivalent to 9 mg of benzyl alcohol per milliliter.
Declared components
Water as the vehicle plus benzyl alcohol as the preservative.
Compatibility, solubility and stability must be verified for each target research material.
Dilution. Dissolution. Controlled repeated access.
The formulation is designed to support laboratory preparation workflows when the target material is documented as compatible with water and benzyl alcohol.
Adjust research concentration
Use validated calculations and the target compound's documented solvent requirements.
Prepare compatible materials
Confirm solubility, pH tolerance and preservative compatibility before preparation.
Inhibits bacterial proliferation
Benzyl alcohol is bacteriostatic; it does not replace aseptic technique or make a contaminated vial sterile.
Where bacteriostatic water fits.
Bacteriostatic water differs from preservative-free sterile water and bacteriostatic saline. These materials are not automatically interchangeable.
Bacteriostatic Water
Water containing benzyl alcohol; repeated access depends on validated handling and manufacturer instructions.
Sterile Water
Contains no bacteriostat and is commonly supplied for single-use workflows.
Bacteriostatic Saline
Contains sodium chloride as well as a preservative and may have different compatibility requirements.
| Diluent | Preservative | Salts | Laboratory consideration |
|---|---|---|---|
| Bacteriostatic Water | Benzyl alcohol | None declared | Verify preservative compatibility |
| Sterile Water | None | None declared | Preservative-free; follow single-use instructions |
| Bacteriostatic Saline | Product dependent | Sodium chloride | Verify salt and preservative compatibility |
Laboratory decision points visualized.
These qualitative indicators summarize formulation considerations rather than efficacy or clinical outcomes.
Benzyl alcohol can be incompatible with some sensitive research compounds.
A laboratory formulation—not a pharmacokinetic active.
Because this product is an aqueous diluent and is sold for research use only, pharmacokinetic claims are not applicable. The relevant characteristics are composition, compatibility, container integrity and handling controls.
Nominal vial volume
Compact fill intended for controlled laboratory workflows.
Benzyl alcohol content
Verify concentration against the actual batch documentation.
Follow manufacturer dating
Do not apply a generic reuse period unless validated for this exact product and container.
This section replaces peptide pharmacokinetics with formulation-specific quality considerations.
3 mL. 0.9% benzyl alcohol. Full formulation specification.
Published specifications should match the authenticated manufacturing and lot documents for the supplied product.
Do not publish USP, nonpyrogenic, endotoxin limit or sterility-test claims unless supported by this product's actual documentation.
A formulation built around documented laboratory controls.
The relevant sequence is a quality workflow rather than a clinical-development timeline.
Verify the target material
Confirm that the research compound is compatible with water and 0.9% benzyl alcohol.
Inspect the vial
Confirm solution clarity, closure integrity, lot number and expiry or retest information before laboratory use.
Use validated aseptic technique
Disinfect the closure and use sterile, appropriate laboratory transfer equipment.
Document preparation
Record volumes, calculated concentration, date, operator and applicable storage conditions.
Inspect and discard when required
Do not use if cloudy, discolored, particulate-containing, damaged or outside documented in-use dating.
Handling and documentation.
Storage and in-use stability must follow the actual label and manufacturer documentation for this 3 mL vial. Generic guidance must not override lot-specific instructions.
Follow labeled storage
Protect the sealed container from inappropriate heat, freezing and physical damage as directed by the manufacturer.
Inspect clarity and seal
Use only when the solution is clear and the container closure is intact.
Track first puncture
Record the opening date and follow the validated in-use period for the exact product.
- Confirm compatibilityReview the research material's solvent, pH and preservative requirements.
- Maintain aseptic controlA bacteriostatic preservative reduces bacterial proliferation; it does not correct contamination.
- Inspect the prepared solutionCheck compatible soluble materials for unexpected precipitation, particles or discoloration.
- Apply compound-specific stabilityStorage and stability of a prepared research solution are governed by the solute and validated preparation—not by the diluent alone.
For laboratory research use only. Not for human or veterinary consumption, administration, diagnosis or treatment. Not for use in neonates. Do not administer bacteriostatic water by itself.
Quality and formulation resources.
Authoritative labeling resources explain the established composition and handling distinctions between bacteriostatic and preservative-free water. The Aurelia product remains governed by its own RUO labeling and batch documentation.
