NuScience Peptides supplies bacteriostatic water (BAC water) for laboratory research use only. Each sterile vial contains 0.9% benzyl alcohol to inhibit bacterial growth, supporting safe multi-dose withdrawal during research protocols. Available in 3ml and 10ml. Not for human consumption.
What Is Bacteriostatic Water Used for in Research?
Bacteriostatic water (BAC water) is a sterile aqueous solution preserved with 0.9% benzyl alcohol. In laboratory research, it serves as the standard diluent for reconstituting lyophilized peptides. The benzyl alcohol content inhibits microbial growth inside the vial, making it suitable for multi-dose withdrawal over extended research protocols.
Key research applications include:
- Reconstituting lyophilized research peptides such as BPC-157, TB-500, GHK-Cu, and GHRP peptides
- Preparing stable multi-dose solutions for controlled in vitro experiments
- Serving as a vehicle for peptide compounds requiring a neutral aqueous medium
- Supporting repeated access to a single vial without contamination under aseptic conditions
To determine the correct BAC water volume for a specific peptide concentration, use the NuScience Peptides Calculator available on the site.
BAC Water vs. Sterile Water: Key Differences for Research
| Feature | Bacteriostatic Water (BAC Water) | Sterile Water |
| Preservative | 0.9% Benzyl Alcohol | None |
| Multi-dose use | Yes – up to 28 days | No – single use only |
| Bacterial inhibition | Yes | No |
| Standard for peptide research | Yes | Limited use cases |
| Vial stability after first puncture | Up to 28 days | Single use |
| Use case | Multi-step research protocols | Single-dose applications |
Reconstitution and Storage Guidelines
Handling Guidelines for Laboratory Research
- Store unopened BAC water vials at room temperature, away from direct sunlight and heat sources
- Once punctured, use within 28 days to maintain research integrity
- Always use proper aseptic technique when withdrawing solution
For guidance on peptide storage conditions, see the NuScience Peptide Handling and Storage page.
Lab Testing and Purity Verification
Every batch of BAC water supplied by NuScience Peptides undergoes third-party laboratory testing. Certificates of Analysis (COAs) confirming benzyl alcohol content and purity are available on the NuScience Lab Test Results page. Accurate research depends on verified reagents – NuScience does not compromise on testing standards.
