Can I use sterile water instead of bacteriostatic water?

For reconstituted solutions used within 24 hours, sterile water is acceptable. For any solution stored beyond 24 hours under refrigeration, bacteriostatic water is strongly preferred — the preservative is what allows extended-life storage.

How long does BAC water itself last?

Sealed BAC water vials have a multi-year shelf life. Once opened, standard guidance is to discard after 28 days of use.

How much BAC water should I order with my peptide?

For most single-peptide protocols, 1 vial of BAC water per peptide vial is sufficient. Researchers working with multiple peptides simultaneously often order larger BAC water volumes for convenience.

Does Noxa Labs BAC water ship together with peptide orders?

Yes — adding BAC water to your order ensures everything arrives in the same cold-chain package, with consistent delivery time across the Philippines.

Bacteriostatic Water (BAC Water) is sterile water for injection containing 0.9% benzyl alcohol (CAS 100-51-6) as a bacteriostatic preservative, conforming to USP specifications. With CAS number 7013-45-8, BAC Water is a standard laboratory diluent used for reconstituting lyophilized research compounds, preparing stock solutions, and serving as a vehicle control in experimental protocols. BAC Water's benzyl alcohol content inhibits microbial growth, permitting multiple entries into a single vial under aseptic technique while maintaining sterility for the labeled period. This product is supplied as a laboratory consumable for research reconstitution purposes only. It is not intended for unauthorized human or veterinary use, and users should follow institutional biosafety and handling guidelines.

BAC Water — Research Reference

Sterile water containing 0.9% benzyl alcohol — the standard diluent for reconstituting lyophilised research peptides.

What is BAC Water?

Bacteriostatic water for injection (BAC water) is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is the standard reconstitution diluent across virtually all research peptide protocols: the preservative extends the usable life of reconstituted peptide solutions stored under refrigeration to several weeks, compared with the 24-hour stability typical of plain sterile water reconstitutions. Every laboratory working with lyophilised peptides should have BAC water on hand.

Mechanism in research literature

The 0.9% benzyl alcohol concentration is bacteriostatic — it prevents bacterial growth without killing existing organisms. This is sufficient for routine peptide research, where the diluent is added to a sterile lyophilised vial and stored refrigerated. Higher preservative concentrations would risk peptide modification reactions; lower concentrations would risk microbial growth during the typical 4-week reconstituted-storage window.

Documented research applications

BAC water is the diluent for essentially every peptide product Noxa Labs supplies. Standard volume per vial is 1–3 mL depending on the working concentration desired.

Reconstitution

No reconstitution required — BAC water is the diluent itself.

Storage & stability

Store BAC water at room temperature, away from direct light. Discard any opened vial after 28 days of use per standard pharmacy guidance.
