Quick answer

For laboratory use, bacteriostatic water is sold online by research suppliers. We found it on five supplier sites. Pharmacies handle the licensed vials, which are labeled Rx only, and the Walmart and Amazon searches showed look-alike products rather than bac water.

The three places people look

WhereWhat we found
Pharmacies (CVS, Walgreens)Could not confirm a listing on either website. The licensed vials carry an Rx only label. See CVS and Walgreens.

Research suppliersFive suppliers listed sealed vials with benzyl alcohol, in 10 mL or 30 mL. Four showed or linked a lot report for the water.

Before you order: the checklist

The same five checks apply wherever you buy. A seller that cannot show them is harder to trust with a lab supply.

5 things to check on any listing

  1. 10.9% benzyl alcoholThe page or label states the preservative and its strength.
  2. 2Sealed vial, clear sizeA sealed vial with the fill volume in mL.
  3. 3Lot report for the waterSterility and endotoxin results for the water itself, by lot.
  4. 4Price per mLDivide the price by total mL, so 10 mL and 30 mL compare fairly.
  5. 5Storage and datesRoom temperature storage, an expiry date and a 28-day open window.

Pharmacies and big retailers

Hospira's licensed vial is labeled Rx only on its official label. Amazon's seller policy on drugs lists prescription drugs among the products sellers cannot list. That explains why marketplace searches fill up with look-alikes. If you need a local option, read bacteriostatic water near me.
