Built for multi-dose use

Bacteriostatic water is sterile water with 0.9% benzyl alcohol. The preservative stops bacterial growth, so one vial can be drawn from again and again.

0.9% benzyl alcohol

The standard bacteriostatic concentration. Keeps the vial usable for up to 28 days after the first puncture.

Crimp-sealed vials

Each 10mL vial arrives with an intact aluminum crimp and flip-off cap. Broken seal? Don’t use it, tell us.

Batch lab reports

A Certificate of Analysis is published for each batch. Open it from the product page or the Lab Reports page.

Packed to survive transit

Vials are cushioned individually and boxed so they arrive intact, whether you order one or twenty-five.

Three steps to reconstitute

Bacteriostatic water is the standard diluent for lyophilized (powdered) vials. Here is the basic process.

BAC WATER POWDER VIAL
  1. 1

    Prep both vials

    Flip off the caps and wipe both rubber stoppers with an alcohol pad. Let them dry for a few seconds.

  2. 2

    Draw the water

    Pull the amount of bacteriostatic water you need into a sterile syringe. The calculator below tells you how much.

  3. 3

    Add it slowly

    Inject down the inside wall of the powder vial, then swirl gently. Never shake. Store as directed for what you mixed.

Straight answers

Sterile water with 0.9% benzyl alcohol added as a preservative. The benzyl alcohol stops bacteria from growing, so one vial can be drawn from more than once. It is the standard diluent for reconstituting powdered vials.

Up to 28 days after the first puncture when stored as directed. Write the date you first used it on the label and discard it after 28 days. Unopened vials are good until the expiry date printed on the label.

Yes, on every order with no minimum. Orders over $200 are upgraded to free UPS 2nd Day Air and orders over $400 to free UPS Next Day Air.

Orders ship within 1 business day, and most orders placed before the daily carrier pickup go out the same day. You get a tracking number by email as soon as the label is created.

It depends on the vial size and the dose you want. Use the reconstitution calculator: enter the milligrams in the vial, the mL of water you add, and your dose, and it shows exactly how many syringe units to draw.

Sterile water has no preservative and is meant for single use. Bacteriostatic water contains 0.9% benzyl alcohol so it can be used for multiple draws over 28 days.
