About Lab Supplies
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is listed here as a laboratory diluent, supplied in sealed 3 ml and 10 ml vials, for preparing solutions of lyophilized peptide reference material in the laboratory.
Each vial is released against the certificate issued for its own lot rather than a generic document. The certificate records the lot code, the assays run on that lot and the accredited laboratory that signed it, so the report can be checked at source. Sold for laboratory research use only, to buyers aged 21 and over. Not for human or veterinary use.

Common questions
What is bacteriostatic water?
Bacteriostatic water is water for laboratory use that carries 0.9% benzyl alcohol, an agent that suppresses bacterial growth inside the vial. It is not a peptide and has no compound activity of its own. This category covers the non-peptide laboratory consumables held in stock, which at present is bacteriostatic water in 3 ml and 10 ml fills.
What is the difference between bacteriostatic water and sterile water?
Sterile water is supplied free of viable organisms but without a preservative, so a vial is intended for a single withdrawal. Bacteriostatic water contains 0.9% benzyl alcohol, which suppresses bacterial growth, so a sealed vial can be sampled more than once under normal laboratory handling. The benzyl alcohol is the whole difference between the two.
What documentation comes with every lot?
Every item on this site is released against a signed certificate for its own lot. Peptide lots carry a seven-item panel: identity and purity by HPLC, net peptide content measured against the labelled fill, a fentanyl screen, heavy metals by ICP-MS, sterility, and endotoxin. The bacteriostatic water lot on file reports purity by HPLC and endotoxin against a stated limit.
How is a certificate checked against the laboratory that issued it?
Each certificate prints a lot code and names the independent laboratory that signed it. That lot code can be quoted to the issuing laboratory to confirm the report at source, rather than relying on the copy published here. The bacteriostatic water lot names its own laboratory on its own certificate, which is not necessarily the laboratory that ran the peptide panels.
What form do the items ship in, how are they stored, and who may buy them?
Peptides in the catalogue ship as lyophilized powder in a sealed vial, with a stated storage condition of minus 20 degrees Celsius, protected from light. Bacteriostatic water ships as a sealed liquid vial in 3 ml or 10 ml. Purchase is restricted to buyers aged 21 and over, for laboratory research use only. Not for human or veterinary use.
