BAC Water vs Sterile Water: Choosing the Right Diluent

Two clear liquids. One protects research vials for weeks; one does not.

Choosing the right diluent for research:

Bacteriostatic Water

• Contains 0.9% benzyl alcohol preservative
• Multi-use safe, up to about 30 days refrigerated
• Inhibits bacterial growth
• Preferred for most research peptide protocols

Sterile Water

• No preservative
• Single-use only
• Higher contamination risk after opening
• Shorter stability window

For multi-dose research workflows, bacteriostatic water wins on reliability.

For Research Use Only. Not for Human Consumption.
