BAC Water 10ml

BAC water 10ml UK from Arma Peptides is a sterile, non-pyrogenic bacteriostatic water formulated for research laboratory use. Each 10ml vial contains 0.9% (9mg/mL) benzyl alcohol as a bacteriostatic preservative, meeting the standard defined by the USP monograph for Bacteriostatic Water for Injection, to help maintain integrity during repeated withdrawals in ongoing research studies.

Key Features of This BAC Water 10ml UK Supply

• Precise Volume: Each 10ml vial is filled under controlled conditions to ensure batch-to-batch consistency.
• Bacteriostatic Preservative: Contains 0.9% benzyl alcohol to inhibit bacterial growth in multi-use laboratory settings.
• pH Range: Maintained between 4.5 and 7.0 for stability during research handling.
• Storage: Recommended ambient laboratory temperature (20–25°C) to preserve quality prior to opening.
• Multi-Dose Container: Suitable for multiple withdrawals in a controlled lab environment.

Laboratory Stability

This BAC water 10ml UK vial is stable for up to 28 days after initial puncture when stored under appropriate laboratory conditions. The benzyl alcohol content helps reduce the risk of microbial contamination across that period, which is why bacteriostatic water — rather than plain sterile water — is the standard choice for multi-dose research protocols.

Safety and Compliance

Supplied strictly for laboratory research use only. Not for human or veterinary use. All handling should follow applicable laboratory safety protocols and legal requirements.

Why Bacteriostatic Water for Peptide Reconstitution

Bacteriostatic water is the standard diluent used in research settings for reconstituting lyophilised peptides such as BPC-157 and TB-500. Unlike plain sterile water, the 0.9% benzyl alcohol content acts as a bacteriostatic preservative, inhibiting bacterial growth across repeated withdrawals from the same vial — a key requirement in laboratories running multi-dose research protocols over several weeks. Researchers reconstituting multiple peptide vials from the same study batch typically prefer BAC water over single-use sterile water for exactly this reason.

Research Handling Guidance

In published research protocols, BAC water is typically added to lyophilised peptide vials in controlled volumes, with the vial swirled gently — not shaken — until fully dissolved. Reconstituted solutions are generally stored refrigerated at 2–8°C between uses, with the vial itself remaining stable for approximately 28 days post-puncture when handled under sterile laboratory conditions. Researchers should always cross-check reconstitution volume and storage requirements against their own study protocol, since exact figures vary by peptide and formulation.

Frequently Asked Questions

What is the difference between bacteriostatic water and sterile water?
Sterile water contains no preservative and is intended for single-use only. Bacteriostatic water contains 0.9% benzyl alcohol, allowing safe multiple withdrawals from the same vial across a research period, provided sterile technique is maintained.

How long does bacteriostatic water last once opened?
Once punctured, bacteriostatic water is generally considered stable for up to 28 days when stored at recommended laboratory conditions, though researchers should always follow their own protocol’s stability guidance.

Can bacteriostatic water be used with any peptide?
BAC water is broadly compatible with most lyophilised research peptides, including BPC-157 & TB-500 blends, but researchers should confirm reconstitution volume and compatibility against their specific study protocol.

Is this product intended for human use?
No. This product is supplied strictly for laboratory and research purposes only and is not approved for human or veterinary administration.

Choosing a UK Supplier for BAC Water

When sourcing BAC water 10ml UK researchers should verify three things before use: the benzyl alcohol concentration is accurately labelled at 0.9%, the vial is sealed and non-pyrogenic, and the supplier tests each production batch rather than relying on a generic specification sheet. Arma Peptides publishes a Certificate of Analysis (CoA) for each batch, giving researchers a documented reference point for pH, sterility, and benzyl alcohol content ahead of use in any study protocol.

Common Research Applications

BAC water is most frequently used to reconstitute lyophilised peptides prior to research protocols involving subcutaneous or intramuscular administration in laboratory animal studies, as well as in vitro dilution work. Because the 0.9% benzyl alcohol preservative allows repeated withdrawals without re-sterilising the vial, a single 10ml supply can support multiple reconstitution events across a single research project, reducing both cost and vial waste compared to single-use sterile water for injection.
