Buy Bac Water Online (With Benzyl Alcohol) | Bacteriostatic Water for Peptide Research
Looking for a reliable source to buy bac water online? Bacteriostatic water (bac water) is sterile water for injection containing 0.9% benzyl alcohol as a preservative. It is the gold standard solvent for reconstituting lyophilized peptides intended for multiple withdrawals over time.
When you choose to buy bac water online, you need a trusted supplier offering pharmaceutical-grade purity, sterile packaging, and verified benzyl alcohol concentration. Below, discover why bacteriostatic water is essential for every peptide research laboratory.
What is Bac Water (Bacteriostatic Water)?
Bacteriostatic water is sterile water for injection that contains 0.9% benzyl alcohol as a bacteriostatic preservative. This additive allows the solution to:
- Prevent bacterial growth – Inhibits contamination after first puncture.
- Enable multiple uses – Safe for repeated withdrawals over 28 days.
- Maintain peptide stability – Provides ideal environment for reconstituted peptides.
- Extend usability – Unlike sterile water, bac water vials can be reused.
This makes bacteriostatic water the preferred solvent for any research protocol requiring multiple doses from a single reconstituted peptide vial.
Key Research Applications
Bac water (with benzyl alcohol) is essential for:
- Peptide Reconstitution – Dissolving lyophilized peptides for multi-dose research.
- Multi-Withdrawal Protocols – Studies requiring multiple injections over days or weeks.
- Laboratory Controls – Vehicle controls with preservative matching.
- Pharmaceutical Research – Reconstituting sterile powders for testing.
- Long-Term Storage Studies – Evaluating peptide stability in preserved solutions.
Bac Water vs. Sterile Water (No Benzyl Alcohol)
| Feature | Bac Water (0.9% BA) | Sterile Water (No BA) |
|---|---|---|
| Benzyl Alcohol | 0.9% preservative | None |
| Antimicrobial | Yes – 28-day multi-use | No – single-use only |
| Best For | Multi-dose research protocols | Single-use, immediate application |
| Cost | Slightly higher | Generally lower |
| Reusability | Yes – up to 28 days | No – discard after single use |
For multi-dose peptide research across days or weeks, bac water is the clear and necessary choice.

⚠️ For laboratory research only. Not for human injection without proper authorization. Benzyl alcohol is contraindicated in neonates and certain research models.
Frequently Asked Questions (FAQs)
Q: Is bac water the same as bacteriostatic water?
A. Yes. “Bac water” is the common abbreviation for bacteriostatic water for injection.
Q: Why is benzyl alcohol added to bac water?
A. Benzyl alcohol (0.9%) acts as a bacteriostatic preservative, preventing bacterial growth after the vial has been punctured multiple times. This allows safe multi-dose use for up to 28 days.
Q: Can I use bac water for all peptides?
A. Most research peptides reconstitute well in bac water. However, some sensitive peptides may degrade faster in the presence of benzyl alcohol. Always check your peptide’s specific reconstitution protocol.
Q: How long does bac water last after opening?
A. A punctured bac water vial remains sterile for 28 days when stored at room temperature and properly handled (alcohol swabs before each draw).
Q: Do I need to refrigerate bac water?
A. No. Unopened or opened bac water vials should be stored at room temperature (15-30°C). Do not freeze. Refrigerate only after mixing with peptides.
Q: How is bac water shipped?
A. In sterile, sealed packaging at room temperature. No special temperature control required.
Safety & Handling Guidelines
| Do’s | Don’ts |
|---|---|
| Use alcohol swab before each puncture | Do not use after 28 days of opening |
| Store at room temperature | Do not freeze |
| Use within 28 days of first use | Do not share vials between researchers |
| Discard if solution appears cloudy | Do not use if seal is broken |
| Label with opening date | Do not autoclave or re-sterilize |
