Bacteriostatic water in Australia: 3 mL or 10 mL?
Research context reviewed 22 October 2026
What BAC water is
BAC water is the usual short name for bacteriostatic water, a laboratory diluent.
PEPTALIAS lists it separately as a laboratory supply. The exact formulation of the vial you receive is printed on its label.
3 mL or 10 mL: the two formats
| Format | Supplied in | Price per vial | Price per mL |
|---|---|---|---|
| BAC Water 3 mL | 3 mL vial | A$11.99 | A$4.00 |
| BAC Water 10 mL | 10 mL vial | A$18.99 | A$1.90 |
Prices are today's prices. Price per mL is the vial price divided by the vial volume.
The larger vial costs less per millilitre; the smaller vial costs less per vial. Choose by the volume your laboratory work needs and by how you plan to store what is left. The vial label governs storage.
What to check on the label
