Bacteriostatic Water

The thing most orders forget

In plain terms

Bacteriostatic water is sterile water with 0.9% benzyl alcohol, which stops bacteria multiplying and lets a vial be used more than once. It is what freeze-dried peptides are reconstituted with, and it is the single most commonly missed item on an order.

Research overview

Bacteriostatic Water (0.9% benzyl alcohol in sterile water) is a standard laboratory reagent used for the reconstitution and dilution of lyophilized compounds in research settings. The benzyl alcohol preservative inhibits bacterial growth, maintaining the sterility of reconstituted solutions across multiple uses in laboratory environments.

What has been studied

1
What it is
Sterile water containing 0.9% benzyl alcohol, which suppresses bacterial growth. It is a laboratory reagent, not a research compound.
2
Why the preservative matters
Plain sterile water has no preservative, so a vial is single-use once opened. The benzyl alcohol is what allows a reconstituted vial to be drawn from more than once.
3
Required for lyophilised vials
Every freeze-dried peptide has to be reconstituted before anything can be measured or handled.
