Bacteriostatic Water is sterile water containing 0.9% benzyl alcohol, a bacteriostatic agent that inhibits microbial growth within the vial. This preservative is what distinguishes it from plain sterile water: it allows the same vial to be accessed repeatedly over an extended working period rather than being discarded after a single draw. It is the standard diluent for reconstituting lyophilized peptides that dissolve readily at neutral pH, giving researchers a clear, stable working solution. Supplied as a laboratory-grade reagent for research and development purposes only. Must be handled by qualified professionals. Not for human, therapeutic, or diagnostic use.
Multi-Draw Capability
The benzyl alcohol preservative inhibits microbial growth, allowing a single vial to be accessed repeatedly across a study.
Near-Neutral pH
Suitable for the majority of lyophilized peptides that dissolve readily without requiring an acidified diluent.
Reduced Vial Waste
Extends the practical working life of a diluent vial compared to single-use sterile water, lowering per-experiment cost.
Consistent Working Stocks
A standardized diluent reduces batch-to-batch variability when preparing stock concentrations across a study.
Standard Lab Reagent
The default reconstitution solvent across most peptide protocols, making results directly comparable to published work.
Laboratory-Grade Preparation
Prepared from sterile water and analytical-grade benzyl alcohol, filtered and sealed for consistent handling.
