Australia's leading bacteriostatic water (BAC water) provider.

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative, supplied in a multiple-dose vial. We stock it two ways: our own-label vials in 10, 20 and 30 mL, labelled not for injection or infusion, and the factory-sealed 30 mL manufacturer presentation, labelled as a diluent or solvent for compatible drugs that require preparation before injection. Read the label of the presentation you choose.
