About this compound
Bacteriostatic Water 3 ml – Sterile Solvent for Peptide Reconstitution
- Composition: 3 ml sterile water for injection with 0.9% benzyl alcohol (preservative)
- Category: Laboratory Solvent / Research Supply
- Form: Sterile, sealed ampoule
- Intended Use: Reconstitution of lyophilized peptides and research compounds
What is Bacteriostatic Water?
Bacteriostatic Water (BW) is a sterile, pyrogen-free solution used as a solvent for the reconstitution of lyophilized research peptides and laboratory compounds. It contains 0.9% benzyl alcohol, which acts as a bacteriostatic preservative that inhibits bacterial growth, allowing the solution to remain stable under sterile conditions for multiple withdrawals.
Essential for precise peptide preparation – designed for controlled, contamination-free reconstitution.
Key Features
Sterile & Pyrogen-Free: Safe for laboratory use in peptide reconstitution.
With Benzyl Alcohol: Inhibits bacterial growth for extended usability after opening.
Precise 2 ml Volume: Ideal for single or small peptide vials.
Compatibility: Suitable for all common lyophilized peptides and lab compounds.
Application
Use aseptic techniques when mixing with lyophilized materials. Withdraw solution only with sterile syringes and needles.
Storage Instructions
- Store at 20–25 °C (68–77 °F) in a clean, dry place.
- Protect from light and heat.
- Discard if the solution becomes cloudy or contaminated.
- Use within 28 days after opening under sterile conditions.
Why Choose This Product?
