What Is Bacteriostatic Water?

Bacteriostatic water is a sterile solution used in laboratories to prepare freeze-dried peptides for research. It contains a small amount of benzyl alcohol (0.9%), which helps prevent bacterial growth once a vial has been opened.

Why Is It Used?

Freeze-dried peptides need to be dissolved into a liquid before they can be studied in solution. Bacteriostatic water is a standard laboratory choice for this step because the benzyl alcohol allows a vial to be used more than once without contaminating the remaining contents.

Common Research Areas

  • Sample preparation
  • Peptide reconstitution
  • Laboratory sterility

Bacteriostatic water is sterile water for injection with 0.9% benzyl alcohol added as a bacteriostatic preservative, permitting multiple withdrawals from a single vial while limiting microbial growth between uses. It's distinct from plain sterile water, which has no preservative and is intended for single use only.

Frequently Asked Questions

Can I use plain sterile water instead?

Plain sterile water has no preservative, so an opened vial is intended for single use only. Bacteriostatic water's benzyl alcohol content is what allows a vial to be used across multiple reconstitutions.

How many times can one vial be used?

This depends on how it's handled in your lab — the benzyl alcohol content extends usability compared to plain sterile water, but sterile technique should still be used for every withdrawal.

Does it expire once opened?

Yes — check the batch documentation for the specific shelf life once opened, and always inspect for clarity before use.
