About BAC Water

Bacteriostatic Water (BAC Water) is a highly purified, sterile water preparation containing 0.9% benzyl alcohol, which acts as a bacteriostatic agent. Unlike standard sterile water, this unique formulation allows for multiple entries into the vial by inhibiting the growth of most potentially contaminating bacteria for up to 28 days after the initial seal is broken. It is the gold-standard solvent used by researchers and laboratory professionals for safely reconstituting lyophilized (freeze-dried) peptides and other compounds, ensuring that your solutions remain stable, sterile, and ready for precise experimental application.  

Technical Specifications & Research Utility The utility of Bacteriostatic Water for Injection, USP, in a laboratory setting cannot be overstated when conducting rigorous scientific research involving the solubilization of polypeptide chains, amino acid derivatives, and complex macromolecules. As a premier reconstitution vehicle, this solvent is critical for maintaining the integrity of research peptides, ensuring that the pharmacological and chemical stability of the solute is preserved post-reconstitution. The inclusion of 0.9% benzyl alcohol serves a dual purpose: it functions as a potent antimicrobial preservative to prevent bacterial colonization that could compromise experimental data, and it acts as a stabilizing co-solvent that aids in the dissolution of hydrophobic compounds.

When sourcing laboratory-grade solvents for the reconstitution of research peptides such as BPC-157, TB-500, Thymosin Alpha-1, and various GLP-1 agonists, it is imperative to utilize a diluent that adheres to strict USP (United States Pharmacopeia) standards for sterility and endotoxin levels. Our 3ML BAC Water vials provide the optimal volume for single-vial peptide reconstitution, minimizing waste while maximizing the shelf-life of the dissolved solution. Researchers utilizing lyophilized proteins often require a solvent that supports multi-dose extraction protocols; the bacteriostatic nature of this water allows for repeated withdrawals from the same vial without the immediate risk of microbial proliferation associated with preservative-free sterile water.  

Furthermore, proper reconstitution techniques using high-quality Bacteriostatic Water are essential for accurate dosing and concentration calculations in biochemical assays. Whether used for in vitro studies, analytical chemistry applications, or chromatography sample preparation, the consistent pH and purity of our BAC Water ensure reproducible results. It is the preferred choice for handling sensitive biological compounds that require a stable, bacteria-inhibiting environment to prevent degradation and hydrolysis. By choosing pharmaceutical-grade Bacteriostatic Water, laboratories ensure the highest standard of hygiene and experimental validity, protecting valuable research materials from cross-contamination and environmental impurities. This product is strictly intended for laboratory research and development purposes and is an indispensable component of any peptide synthesis or analysis toolkit.
