Bacteriostatic water is a sterile aqueous solution containing 0.9% benzyl alcohol as a bacteriostatic preservative. The preservative inhibits bacterial growth so a sealed multi-dose vial can be accessed more than once, which makes it a common laboratory diluent for reconstituting lyophilized (freeze-dried) research compounds. Available in 3 mL and 10 mL multi-dose vials.

  • Preservative: 0.9% Benzyl Alcohol
  • Sterility: USP-grade, sterile filtered
  • Container: Multi-dose glass vial, self-sealing stopper
  • Sizes: 3 mL and 10 mL
  • Storage: Room temperature (15–25°C / 59–77°F), protect from light

Common questions about this product

What is bacteriostatic water?

Bacteriostatic water is sterile water that contains 0.9% benzyl alcohol as a bacteriostatic preservative, which inhibits the growth of bacteria so a sealed multi-dose vial can be accessed more than once. In the laboratory it is commonly used as a preserved diluent for reconstituting lyophilized research compounds. Sold strictly for research use only.

What sizes do you offer — 3 mL or 10 mL?

We stock two multi-dose vial sizes: 3 mL and 10 mL. The 3 mL vial suits small or single-compound reconstitution; the 10 mL vial is better value for labs reconstituting several vials. Choose your volume from the options on this page.

How much bacteriostatic water do I need to reconstitute a peptide?

It depends on the milligrams of compound in the vial and the concentration your protocol calls for — often roughly 1–3 mL of diluent per vial. Our step-by-step bacteriostatic water reconstitution guide walks through the calculation with worked examples.

How long is bacteriostatic water good for once opened?

Because the 0.9% benzyl alcohol preservative is bacteriostatic, an opened multi-dose vial is generally usable for up to 28 days when kept sealed between draws and handled with standard aseptic technique. Discard sooner if the solution is no longer clear and colorless.

How should bacteriostatic water be stored?

Store unopened vials at controlled room temperature (20–25°C / 68–77°F), away from direct light. Keep the vial sealed until use and handle under aseptic technique in your research environment.

Where can I order bacteriostatic water and how fast does it ship?

You can order bacteriostatic water directly on this page in 3 mL or 10 mL vials. Orders placed before 2:00 PM Pacific (Mon–Fri) ship the same day via FedEx 2-Day Express; free shipping on orders of $200 or more, flat $12 otherwise.

Is this for research use only?

Yes. Bacteriostatic water is supplied strictly for laboratory research and development use. It is not intended for human or animal consumption, therapeutic use, or any clinical application.
