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.
