Why You Need Bacteriostatic Water

Every lyophilized peptide requires reconstitution before use. Bacteriostatic water — sterile water with 0.9% benzyl alcohol — is the industry standard diluent. The benzyl alcohol inhibits bacterial growth, allowing multi-dose use from a single vial for up to 28 days when refrigerated.

Without proper bacteriostatic water, reconstituted peptides degrade faster and present contamination risks. Our bac water is sterile filtered through 0.2µm membranes and filled in a controlled environment — the same quality standard used in regulated pharmaceutical research.

Usage Instructions

📖 Protocol

  1. 1. Sanitize the rubber stopper of both vials with an alcohol swab.
  2. 2. Draw the required volume of bac water into a sterile syringe.
  3. 3. Inject slowly along the inner wall of the peptide vial — not directly onto the powder.
  4. 4. Gently swirl (do not shake) until fully dissolved.
  5. 5. Store reconstituted peptide at 2-8°C. Use within 7-14 days.

Bacteriostatic Water FAQ

What is bacteriostatic water used for?

Bacteriostatic water is sterile water for injection containing 0.9% benzyl alcohol. It is used to reconstitute lyophilized (freeze-dried) peptides for research. The benzyl alcohol prevents bacterial growth after the vial is punctured, allowing multi-dose use over 7-14 days when refrigerated.

How long does BAC water last after opening?

An opened 30mL vial of bacteriostatic water lasts approximately 28 days when stored at 2–8°C (refrigerated) and used with sterile technique. After 28 days, or sooner if the solution becomes cloudy or discolored, discard the vial.

Can I use sterile water instead of bacteriostatic water?

Sterile water (without benzyl alcohol) can be used for single-dose reconstitution but is not suitable for multi-dose protocols. Unlike bacteriostatic water, sterile water contains no preservative, meaning any punctured vial must be used immediately and discarded. For most research protocols, bacteriostatic water is preferred.
