Overview
Bacteriostatic Water for Injection is a sterile, non-pyrogenic preparation of water for injection containing 0.9% w/v benzyl alcohol as a preservative. The benzyl alcohol content inhibits bacterial growth and permits repeated access of a single vial without microbiological compromise over the standard 28-day multi-dose period. It is an essential laboratory solvent for the reconstitution of lyophilised research compounds.
Scientific Overview
Bacteriostatic Water is the standard diluent used for reconstituting lyophilised peptides, proteins, and hormones in research settings. The benzyl alcohol preservative allows multiple withdrawal events while maintaining sterility, which is critical in longitudinal research protocols. Studies have characterised the compatibility of bacteriostatic water with a wide range of peptide structures. Researchers should note that benzyl alcohol-containing diluents may be incompatible with certain compounds sensitive to aromatic solvents.
Mechanism of Action
Benzyl alcohol (C6H5CH2OH) acts as a bacteriostatic preservative by disrupting bacterial cell membrane integrity and inhibiting metabolic enzymes, preventing microbial proliferation without sterilising the solution. This contrasts with sterile water for injection, which must be used as a single-dose preparation. The 0.9% benzyl alcohol concentration is established as effective against common environmental contaminants while remaining compatible with most peptide research compounds under standard storage conditions.
Areas of Research
Third-Party Testing
Every batch of Bacteriostatic Water supplied by Pure Recovery Labs is independently analysed by a third-party laboratory prior to release. Purity is confirmed via HPLC and mass spectrometry to a minimum of 99%. A certificate of analysis is accessible via QR code on each product and through the Quality page.
