Technical specifications
Bacteriostatic water is sterile water for injection containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits bacterial growth, allowing the vial to be punctured multiple times without contamination — unlike standard sterile water for injection (SWFI) which is single-use only. It is the standard reconstitution solvent used in laboratory settings for lyophilized peptide compounds. The benzyl alcohol preservative is pharmacopeially recognized and used across research and clinical-grade formulations.
- 0.9% benzyl alcohol functions as a bacteriostatic (growth-inhibiting) preservative
- Multi-dose use is possible due to the preservative; SWFI is single-use only
- USP-grade benzyl alcohol has a well-documented pharmacopoeial safety profile
- Standard diluent for lyophilized peptide reconstitution in research settings
- pH buffered to maintain peptide stability upon reconstitution
- Not for intravenous use; intended for laboratory reconstitution of research compounds only
