BAC Water (10mL)

Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. This preservative property allows the vial to be used for multiple draws over time without contamination — making it the standard diluent for reconstituting lyophilized research peptides.

BAC Water (10mL) is used to reconstitute lyophilized (freeze-dried) peptide powders before use in research protocols. Adding BAC water to a lyophilized peptide vial dissolves the powder into a stable, multi-dose solution. The 10mL format is especially suited to researchers running longer protocols, working with multiple peptide compounds simultaneously, or reconstituting higher-quantity vials such as 30mg peptide formats.

The formulation is identical — both contain 0.9% benzyl alcohol in sterile water for injection. The only difference is total volume. The 3mL vial is suited to single-compound, shorter-term research protocols, while the 10mL vial provides greater reconstitution capacity for researchers managing multiple vials or extended workflows. Both formats preserve solution integrity across multiple draws when stored and handled correctly.

The volume added depends on the desired concentration. A common approach for a 10mg peptide vial is to add 1–2mL of BAC water, yielding a concentration of 10mg/mL or 5mg/mL respectively. For a 30mg vial, adding 3mL gives 10mg/mL. Use a sterile insulin syringe to inject the BAC water slowly down the inside wall of the peptide vial, then gently swirl to dissolve — do not shake.

Store unopened BAC Water (10mL) vials at room temperature, protected from light. Once opened, refrigerate and handle aseptically during each withdrawal using a sterile syringe. Discard any vial that shows cloudiness, particulates, or signs of contamination.

Yes. BAC Water is available in Australia through Aussie Peptides in both 3mL and 10mL sterile vials, with fast domestic shipping to all states and territories.

Aussie Peptides offers bacteriostatic water in two sizes: a 3mL vial for standard single-compound research use, and a 10mL vial for extended protocols and multi-compound setups. Both contain 0.9% benzyl alcohol in sterile water for injection, individually sealed under sterile conditions, and suitable for multi-dose use. Researchers needing a larger format can also view our partner listings for BAC Water (10mL), BAC Water (20mL) and Hospira BAC Water (30mL), supplied via our trusted partner AusBacSupply.

BAC Water (10mL) is currently out of stock but will be restocked soon at Aussie Peptides. Once available, it will be supplied domestically with tracked Australian shipping to all states and territories.
