Bacteriostatic Water Overview

The standard diluent for mixing lyophilized research peptides.

Technical overview

Bacteriostatic water is sterile water with 0.9% benzyl alcohol. The benzyl alcohol stops bacteria from growing, so a vial can be opened and drawn from repeatedly for up to 28 days, unlike plain sterile water, which is single-use.

Research applications

It is used to reconstitute freeze-dried peptide powder into a solution. Our peptide calculator works out how much water to add for a given concentration.

FAQs

  • What is bacteriostatic water?

    Sterile water with 0.9% benzyl alcohol, a preservative that stops bacteria from growing, so the vial can be drawn from more than once.

  • What is bacteriostatic water used for?

    It is the standard diluent for reconstituting lyophilized research peptides: it dissolves the freeze-dried powder in the peptide vial into a solution. To work out how much to add for a given concentration, use our peptide reconstitution calculator.

  • What is the difference between bacteriostatic water and sterile water?

    Sterile water has no preservative, so it is meant for single use. The benzyl alcohol in bacteriostatic water keeps it usable for up to 28 days after the vial is first opened.

  • How should bacteriostatic water be stored?

    Unopened, at room temperature, 68–77°F (20–25°C). Once the stopper is punctured, date the vial and use it within 28 days. More in our guide, Do peptides need to be refrigerated?

  • What size is Research Water?

    Research Water comes in a 10mL vial.

  • Is Research Water for human use?

    No. It is sold for laboratory research use only.
