Bacteriostatic Water for Peptide Research
What is Bacteriostatic Water?
Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol, a bacteriostatic preservative that inhibits the growth of bacteria. This makes it ideal for reconstituting lyophilized (freeze-dried) peptides for research applications where multiple withdrawals from the same vial are needed.
Key Features
USP Grade Quality
Our bacteriostatic water meets United States Pharmacopeia (USP) standards for:
- Sterility
- Purity
- Benzyl alcohol concentration (0.9%)
- Endotoxin levels
Multi-Use Design
Unlike single-use sterile water, bacteriostatic water allows multiple withdrawals over several weeks without contamination risk, making it cost-effective for research laboratories.
Convenient 10ml Size
Each 10ml vial can reconstitute 5-10 peptide vials depending on concentration requirements.
How to Use Bacteriostatic Water
Reconstitution Steps
- Allow the peptide vial to reach room temperature
- Clean both vial tops with an alcohol swab
- Using a sterile syringe, withdraw the desired amount of bacteriostatic water
- Insert the needle into the peptide vial, aiming at the glass wall
- Slowly inject the water, allowing it to run down the vial wall
- Gently swirl (do not shake) until fully dissolved
- Store reconstituted peptide at 2-8°C
Recommended Volumes
| Peptide Amount | Suggested BAC Water | Concentration |
|---|---|---|
| 5mg | 1.0ml | 5mg/ml |
| 5mg | 2.0ml | 2.5mg/ml |
| 10mg | 2.0ml | 5mg/ml |
| 10mg | 4.0ml | 2.5mg/ml |
Storage Instructions
- Unopened: Store at room temperature (15-25°C), away from direct light
- Opened: Use within 28 days
- Do not freeze: Freezing may compromise sterility
- Shelf life: 2 years from manufacture date
Applications in Research
Bacteriostatic water is essential for:
- Peptide reconstitution for in vitro studies
- Preparation of stock solutions
- Multi-day research protocols requiring repeat sampling
- Any application where sterility must be maintained over time

FAQ
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. It's used to reconstitute lyophilized peptides for multi-use applications.
Bacteriostatic water contains benzyl alcohol which prevents bacterial contamination after opening. This allows multiple withdrawals from a vial over several weeks, unlike single-use sterile water.
Peptides reconstituted with bacteriostatic water can typically be stored at 2-8°C for 2-4 weeks. Always follow the specific guidance for each peptide.
Yes, our bacteriostatic water meets USP (United States Pharmacopeia) standards for sterility, purity, and benzyl alcohol concentration.
Typically 1-2ml per peptide vial is recommended. The exact amount depends on your desired concentration. Each 10ml vial can reconstitute 5-10 peptide vials.
Freezing is not recommended as it may affect sterility and cause the vial to crack. Store at room temperature (15-25°C) away from direct light.
Unopened bacteriostatic water has a shelf life of 2 years when stored properly. Once opened, use within 28 days.
We recommend using insulin syringes with a 29-31 gauge needle for accurate measurement. Always use a new sterile syringe for each withdrawal.
