Bacteriostatic Water (BAC) - 30mL

• USP-Grade Quality — Manufactured in accordance with USP specifications for Bacteriostatic Water for Injection, ensuring consistent quality and suitability for laboratory research applications.
• Multi-Dose Convenience — The inclusion of 0.9% benzyl alcohol helps inhibit bacterial growth after initial puncture, allowing multiple withdrawals under proper laboratory handling procedures.
• Ideal for Peptide Reconstitution — Commonly used as the preferred diluent for reconstituting lyophilized research peptides intended for repeated laboratory use.
• Sterile Manufacturing — Sterile-filtered and aseptically filled to maintain product integrity until first use.
• Canadian Inventory — Ships directly from within Canada, providing faster delivery times and reducing delays associated with international shipping.
• Laboratory Workflow Efficiency — The 30 mL multi-dose format supports routine peptide preparation while reducing the frequency of replacing reconstitution solutions.

Researchers purchasing bacteriostatic water commonly pair it with lyophilized peptides requiring reconstitution prior to laboratory use. Frequently ordered products include:

• BPC-157 — A research peptide extensively investigated in connective tissue, angiogenesis, and regenerative biology studies, commonly reconstituted with bacteriostatic water.
• TB-500 — A synthetic thymosin beta-4 peptide frequently studied for cell migration, tissue remodelling, and regenerative research applications.
• Retatrutide — A next-generation metabolic research peptide commonly supplied in lyophilized form and prepared using bacteriostatic water before laboratory investigation.
• Wolverine Stack — A research kit combining BPC-157 and TB-500, often paired with BAC water for convenient peptide reconstitution in regenerative biology studies.

What is the difference between bacteriostatic water and sterile water for injection?

The primary difference is the presence of 0.9% benzyl alcohol. Sterile water for injection contains no preservative and is generally intended for single-use applications once opened. Bacteriostatic water contains benzyl alcohol to inhibit bacterial growth, making it suitable for laboratory protocols involving multiple withdrawals from the same vial under appropriate handling procedures.

Is bacteriostatic water the same as saline?

No. Normal saline contains 0.9% sodium chloride, whereas bacteriostatic water contains 0.9% benzyl alcohol and no sodium chloride. Because these solutions have different compositions and intended laboratory uses, they should not be considered interchangeable unless specifically indicated by a research protocol.

How should BAC water be stored?

Bacteriostatic water should be stored at room temperature and protected from freezing. Before opening, the vial remains sterile and sealed under aseptic conditions. After the first puncture, laboratories typically follow the manufacturer's handling recommendations and standard laboratory practices regarding storage and usage timelines.

Can bacteriostatic water be used to reconstitute research peptides?

Yes. Bacteriostatic water is widely used as the preferred diluent for reconstituting many lyophilized research peptides intended for repeated laboratory use. Its preservative system allows multiple withdrawals from the same vial when proper aseptic laboratory techniques are followed.
