Bacteriostatic Water — Reconstitution Solvent (30 mL)
Pre-clinical repair models — built around angiogenic and actin-dynamic pathways.
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is the standard reconstitution solvent for lyophilized research peptides — the preservative allows multi-dose use from a single vial over a research window.
What reconstitutes with this vial
Bacteriostatic water is the standard solvent for every lyophilized peptide on Tidemaxxing. The 0.9% benzyl alcohol holds sterility for up to 28 days once the seal is broken, which matches the shelf-life of most reconstituted research peptides at 2–8 °C.
Shelf life and handling
- Sealed vial
- 24 months at room temperature, protected from light
- After puncture
- 28 days at 2–8 °C with benzyl-alcohol preservative
- Freezing
- Not recommended — repeated freeze/thaw reduces sterility margin
- Re-use
- Single multi-dose vial; wipe septum with alcohol between draws
Storage and shelf-life
Store at 20–25 °C. Protect from light. Expires 28 days after first puncture per standard bacteriostatic-water handling.
Handling in the lab
Use sterile technique when drawing from the vial. Most research protocols use 1–3 mL of BAC water per peptide vial to achieve the target working concentration.
Frequently asked
What is the difference between BAC water and sterile water?
BAC water contains 0.9% benzyl alcohol as a bacteriostatic agent. Sterile water contains only sterile water — no preservative, meaning reconstituted solutions must be used immediately.
Why 28-day expiry?
The bacteriostatic action of 0.9% benzyl alcohol is reliable for approximately 28 days from first puncture. Beyond that, sterility can no longer be assumed.
What is USP-grade BAC water?
Meeting United States Pharmacopeia standards for purity, sterility, and preservative concentration.
Can I use it for any peptide?
Standard practice in research, with rare exceptions — a small number of peptides interact with benzyl alcohol and require sterile water instead.
