BAC Water (Bacteriostatic Water for Injection USP) – Research Grade
BAC Water, also known as Bacteriostatic Water for Injection (USP), is a sterile, non-pyrogenic aqueous solution containing 0.9% benzyl alcohol. It is widely used in laboratory and research settings for the reconstitution of lyophilized peptides, allowing controlled multi-use of a single vial for up to 28 days after opening.
At Peptides Skin, BAC Water is supplied exclusively for research and in-vitro laboratory applications, with consistent quality standards and documentation suitable for professional research environments.
Main Features of BAC Water
- Sterile water with 0.9% benzyl alcohol (9 mg/mL)
- Bacteriostatic properties supporting multi-dose laboratory use
- Clear, colorless, research-grade solution
- USP-compliant formulation for laboratory workflows
- Suitable for peptide and biochemical research applications
Typical Laboratory Applications
- Reconstitution of lyophilized research peptides
- Preparation of short-term working solutions
- Laboratory protocols requiring repeated vial access
- Controlled in-vitro research procedures
What Is BAC Water Used For in Peptide Research?
In peptide research, BAC Water is primarily used as a solvent to dissolve freeze-dried (lyophilized) peptides. The presence of benzyl alcohol inhibits bacterial growth, making it ideal for experiments that require multiple withdrawals from the same vial over several days.
How Long Is BAC Water Good For After Opening?
Once opened, BAC Water is considered stable for up to 28 days when stored properly. This timeframe is based on preservative efficacy and standard laboratory guidelines. Vials should be labeled with the opening date and discarded after 28 days.
Does BAC Water Need to Be Refrigerated?
Unopened BAC Water should be stored at controlled room temperature (20°C–25°C). After opening, refrigeration at 2°C–8°C is recommended to maintain stability and reduce contamination risk. Do not freeze.
Is BAC Water the Same as Sterile Water?
No. While both are sterile, BAC Water contains benzyl alcohol, which provides bacteriostatic protection. Sterile Water for Injection does not contain preservatives and must be discarded immediately after opening, making it unsuitable for multi-use applications.
