What is bacteriostatic water used for in the lab?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, a preservative that inhibits bacterial growth. Laboratories use it as a diluent to reconstitute lyophilised peptides when a stock solution will be sampled more than once.
For single-use preparations, sterile water without preservative is an alternative. Some peptides that dissolve poorly at neutral pH are first dissolved in dilute acetic acid. The laboratory reconstitution guide covers diluent choice, aliquoting and storage.
Lab consumables: frequently asked questions
What is bacteriostatic water?
Sterile water containing 0.9% benzyl alcohol. The benzyl alcohol inhibits bacterial growth, so a reconstituted stock can be sampled more than once.
Is bacteriostatic water included with peptide orders?
No, it is sold separately so laboratories can choose their own diluent. Research kits include it where appropriate.
