Where to Buy Bacteriostatic Water in the UK

Every lyophilised peptide needs a diluent, and bacteriostatic water is the standard choice for reconstituting them in the lab. What UK researchers want is a sterile, correctly preserved supply from a dependable domestic source. This guide explains what bacteriostatic water is, what to check, and how to add it alongside your compounds from Peptura.

What is bacteriostatic water?

Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol, used to dilute and reconstitute lyophilised research peptides in the laboratory. That 0.9% benzyl alcohol holds back microbial growth, so a single vial can be drawn on across several reconstitution sessions without contamination. It is supplied for in-vitro laboratory use only, not for human or veterinary use.

Published research on Benzyl alcohol preservative is indexed on PubMed.
