30mL Bacteriostatic Water (BAC Water) — US Pharmaceutical Grade

Description

Bacteriostatic Water (BAC Water) is sterile water containing 0.9% benzyl alcohol as a preservative, designed for multi-dose use in laboratory research settings. The benzyl alcohol content inhibits microbial growth, extending the usable life of reconstituted solutions compared to standard sterile water. It is the standard reconstitution medium used across preclinical peptide research applications.

US Pharmaceutical-Grade Sourcing Synova Supply’s bacteriostatic water is sourced exclusively from US-licensed pharmaceutical manufacturers operating under FDA current Good Manufacturing Practice (cGMP) regulations. This matters significantly in a research context. Overseas-sourced BAC water — increasingly common in the research supply market — is frequently produced outside cGMP-regulated environments, with inconsistent benzyl alcohol concentrations, variable endotoxin levels, and limited sterility documentation. US-manufactured pharmaceutical-grade BAC water is held to defined specification limits at every stage of production, from water purification through filling and sealing.

Benzyl Alcohol Concentration Consistency The 0.9% benzyl alcohol concentration is not merely a label claim — it is verified analytically in US-manufactured product. Inconsistent preservative concentration in overseas BAC water is a documented quality concern, with some products testing significantly outside labeled specifications. Under-concentration reduces antimicrobial efficacy and shortens the safe multi-dose window of reconstituted peptide solutions. Over-concentration introduces cytotoxicity risk in sensitive cell-based assay systems. Verified concentration consistency is a non-negotiable quality parameter for serious research applications.

Reconstituted Peptide Stability When lyophilized peptides are reconstituted with properly formulated bacteriostatic water, the benzyl alcohol preservative maintains solution stability and inhibits microbial contamination across multiple draws from the same vial. Research literature consistently demonstrates that peptides reconstituted in pharmaceutical-grade BAC water maintain greater stability over time compared to those reconstituted in sterile water or substandard BAC water, particularly when stored at 2–8°C between uses.

Compatibility Compatible with all Synova Supply lyophilized research peptides. Use a fresh sterile syringe and needle for each draw. Store reconstituted peptide solutions at 2–8°C and use within the timeframe specified on the product CoA.
