What is Bacteriostatic Water 30mL?

Bacteriostatic Water 30 mL 10-vial pack is a sterile, non-pyrogenic preparation of water for Injection, USP (H₂O) that contains 0.9% benzyl alcohol. It is used as a bacteriostatic preservative. It is supplied as a research-use-only (RUO) laboratory reference diluent for controlled scientific workflows. The preservative prevents bacterial growth after the vial has been initially accessed. This allows multiple uses when handled according to validated laboratory protocols. This 25-vial pack contains twenty-five 30 mL vials intended exclusively for research, analytical, and educational laboratory applications and is not intended for human or veterinary use.

How Does Bacteriostatic Water 30mL 25 Vial Work?

Bacteriostatic Water 30mL 25 Vial pack functions as a sterile laboratory diluent used during reagent preparation, analytical testing, and method development. It is particularly used in studies involving peptide solutions. Unlike preservative-free sterile water, it contains 0.9% benzyl alcohol, which helps stop bacterial growth after the first puncture of the vial. This feature helps with repeated sample withdrawals under controlled laboratory conditions. It maintains product integrity when proper aseptic techniques are followed, particularly when using bacteriostatic water for Injection. Because it contains no active pharmaceutical ingredient, bacteriostatic water does not produce biological or therapeutic effects. Its role is to provide a standardized aqueous medium for laboratory research requiring a sterile reference solution.

Laboratory Handling of Bacteriostatic Water 30mL

Bac Water 30mL should only be handled by qualified laboratory personnel according to the institutional protocols and Good Laboratory Practice standards. Appropriate aseptic techniques should be maintained during every withdrawal to preserve sterility and minimize contamination risks. The 25-vial product is commonly referenced during:

• Reagent reconstitution
• Laboratory method development
• Analytical testing
• Scientific research workflows
• Educational laboratory activities

Precautions When Handling Bacteriostatic Water 30mL

The Hospira Bacteriostatic Water should only be used in controlled laboratory environments. Consider that:

• It is designed for Research Use Only (RUO).
• It is not suitable for human or veterinary use.
• The bac water shouldn't be used for diagnosis, treatment, or prevention of disease.
• Handle using validated laboratory procedures and aseptic techniques.
• Store according to the manufacturer's recommended storage conditions.
• Use only by qualified laboratory personnel.

Bacteriostatic Water FAQs

Let’s answer your questions about Bacteriostatic Water 30 mL 25-Vial.

What is bacteriostatic water for Injection?

The Bacteriostatic Water 30 mL 25-Vial Pack is a sterile, non-pyrogenic preparation for Injection, USP (H₂O), containing 0.9% benzyl Alcohol as a preservative. It is widely used for controlled laboratory and research use only (RUO) designation. 

What is the difference between bacteriostatic water and sterile water?

Hospira Bacteriostatic Water contains 0.9% benzyl alcohol added as a bacteriostatic preservative. The sterile water formulation does not contain an active pharmaceutical ingredient.

Why is benzyl alcohol added to bacteriostatic water?

Benzyl alcohol is used in Hospira bacteriostatic water as a preservative that prevents bacterial growth after the vial has been opened.

How is bacteriostatic water used in laboratory research?

In a controlled research environment, bacteriostatic water is used as a reference diluent for applications like reagent reconstitution and analytical testing. However, it is important to follow the applicable research protocol.

Can bacteriostatic water be used for multiple withdrawals?

Yes. The presence of benzyl alcohol prevents bacterial growth once the first vial entry is made. This helps with multiple withdrawals under appropriate controlled conditions.
