Bacteriostatic Water 3mL – Caurey Pauling

Description and Effects

Bacteriostatic Water 3ml Amp by Corey Pauling is a sterile, non-pyrogenic water solution containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is commonly used for the reconstitution and dilution of lyophilized peptides and other injectable compounds. The addition of benzyl alcohol helps inhibit bacterial growth, making it a preferred choice for maintaining sterility during peptide preparation.

Product Benefits

• Ideal for Peptide Reconstitution : Designed for mixing and reconstituting lyophilized peptides and research compounds.
• Bacteriostatic Protection : Contains 0.9% benzyl alcohol to help inhibit bacterial growth and reduce the risk of contamination.
• Sterile and Non-Pyrogenic : Manufactured under strict quality standards to ensure purity and reliability.
• Convenient 3ml Ampoule : Practical format for accurate peptide dilution and small-volume applications.
• Easy Handling : Suitable for precise reconstitution protocols commonly used with peptide products.

Bacteriostatic Water vs Sterile Water

Although both solutions are sterile, Bacteriostatic Water contains 0.9% benzyl alcohol, which acts as a preservative to help inhibit bacterial growth after opening. Sterile Water contains no preservative and is generally intended for immediate use once opened. For peptide reconstitution and ongoing handling under sterile conditions, Bacteriostatic Water is often preferred due to its additional protection against contamination.

Peptide Stability After Reconstitution

When used with bacteriostatic water, reconstituted peptides generally remain stable for approximately 14 to 28 days when stored at 2–8°C in a refrigerator. The bacteriostatic agent helps reduce bacterial growth and supports maintaining solution integrity during this period when proper sterile handling is respected.

With sterile water, reconstituted peptides are intended for immediate use or very short-term storage, typically within 24 to 72 hours when refrigerated. Without any antimicrobial preservative, the risk of contamination increases rapidly after opening.

Stability can still vary depending on the specific peptide, as some compounds degrade faster over time regardless of the diluent used.

Usage Recommendations

• Application : Add the desired amount of Bacteriostatic Water to the peptide vial according to your reconstitution protocol.
• Mixing Method : Slowly inject the solution against the inside wall of the vial to minimize foaming and preserve peptide integrity.
• Handling : Always use sterile syringes and aseptic techniques during preparation.
• Storage : Store in a cool, dry place away from direct sunlight and excessive heat.

Precautions and Well-being

• Inspect Before Use : Do not use if the ampoule is damaged or if the solution appears cloudy or contains particles.
• Sterile Technique Required : Proper handling is essential to maintain product sterility.
• For Reconstitution Purposes : Intended for dilution and preparation of compatible compounds.
• Keep Out of Reach of Children : Store safely and handle responsibly.
