Definition
Bacteriostatic water (BAC water) is sterile water containing a bacteriostatic preservative, commonly used as a research diluent in multi-draw laboratory workflows when validated by institutional SOP.
For research and laboratory use only. Not for human consumption, medical use, or personal application.
When laboratories select BAC water
BAC water may be selected when SOP allows multiple draws from a preparation vial within a defined timeframe.
Compare with sterile water for single-use preparation requirements.
VaultLabs catalog
VaultLabs supplies BAC water in 3 mL and 10 mL research vials alongside peptide catalog materials.
Verify lot documentation via batch verification when COA is published.
