BACTERIOSTATIC WATER
Bacteriostatic Water Guide
Everything you need to know about bacteriostatic water (BAC)
What is Bacteriostatic Water?
Bacteriostatic water is sterile distilled water containing 0.9% sodium chloride and 0.9% benzyl alcohol. It is commonly used in research as a solvent for peptides and other compounds. The benzyl alcohol acts as a preservative, inhibiting bacterial growth.
Chemical Formula
H₂O + 0.9% NaCl + 0.9% Benzyl Alcohol = Bacteriostatic Water
Reconstitution Dosage Table
| Vial Size | BAC Water | Concentration |
|---|---|---|
| 5mg | 1mL | 5mg/mL |
| 5mg | 2mL | 2.5mg/mL |
| 10mg | 1mL | 10mg/mL |
| 10mg | 2mL | 5mg/mL |
| 10mg | 4mL | 2.5mg/mL |
Steps to Use
- 1Remove BAC water from refrigerator and allow to reach room temperature
- 2Clean the top of the vial with an alcohol pad
- 3Load syringe with the appropriate amount of BAC water
- 4Slowly inject into the peptide vial
- 5Let sit for 5-10 minutes without shaking
- 6Solution should be clear before use
- 7Store at 2-8°C for maximum stability
Storage
Store in the refrigerator at 2-8°C. Once opened, BAC water remains stable for approximately 30 days when stored properly.
