Where to Buy Bacteriostatic Water in the UK

Bacteriostatic water is the standard diluent for reconstituting lyophilised research peptides in the laboratory. UK researchers need a sterile, correctly preserved supply from a reliable domestic source. This guide explains what bacteriostatic water is, what to check when sourcing it in the UK, and where you can buy it alongside your research compounds from UK Peptide Lab.

What is bacteriostatic water?

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is used for the dilution and reconstitution of lyophilised research peptides in laboratory settings. The 0.9% benzyl alcohol concentration inhibits microbial growth, allowing a vial to be used across multiple reconstitution sessions without contamination. It is supplied for in-vitro laboratory use only, not for human or veterinary use.
