Overview
Bacteriostatic Water (BAC Water) is sterile water containing 0.9% benzyl alcohol as a preservative. It is the standard solution used to prepare lyophilized (freeze-dried) research compounds. Unlike plain sterile water, the benzyl alcohol prevents bacterial growth allowing the vial to be used multiple times safely.
Research Areas
- ✓Essential for preparing all lyophilized research compounds
- ✓0.9% benzyl alcohol prevents bacterial contamination
- ✓Multi-dose safe — vial can be used multiple times
- ✓Stable for 28 days after opening when refrigerated
- ✓Pharmaceutical grade sterility
- ✓Compatible with all research compounds

Frequently Asked Questions
Can I use sterile water instead of BAC water?
Plain sterile water has no preservative so once the vial is punctured it must be used immediately. BAC water is strongly preferred for all research compound research as it allows safe multi-dose use over weeks.
How much BAC water do I add to my research compound?
Use the preparation calculator in our Guides section. The amount depends on the research compound vial size and your desired concentration.
How long does BAC water last after opening?
Refrigerated BAC water is generally considered stable for 28 days after the first puncture. Always check for cloudiness or particles before use.
Does it matter which supplier I buy BAC water from?
All pharmaceutical grade BAC water is 0.9% benzyl alcohol in sterile water. Price and vial size are the main differences between suppliers — use this comparison to find the best value.
