Description
Key Research Features of Bacteriostatic Water
- Sterile, non-pyrogenic water containing 0.9% (9 mg/mL) benzyl alcohol as a bacteriostatic preservative.
- Benzyl alcohol helps inhibit bacterial proliferation, supporting multi-use access from a single vial under appropriate aseptic handling.
- Commonly used as a solvent or diluent for compatible substances in peptide, biologic, and small-molecule research workflows.
- Manufactured to pharmaceutical-grade standards and supplied with third-party lab analysis to support reproducible experimental results.
Why Researchers Choose Peak Science Peptides Bacteriostatic Water
- Pharmaceutical-grade production aligned with USP-style specifications for sterile solutions containing benzyl alcohol.
- Third-party certificates of analysis (COAs) verifying composition, pH range, and absence of microbial contamination.
- Reliable lot-to-lot consistency for peptide reconstitution, small-volume dilutions, and multi-vial assay workflows.
- Clearly labeled for research use only to support compliance in academic, industrial, and contract research laboratories.
Research Use Only – Important Notice
Bacteriostatic Water from Peak Science Peptides is intended exclusively for controlled laboratory experimentation, including in vitro and other approved research applications. It is not approved as a therapeutic product and must not be used for diagnosis, treatment, or any form of administration to humans or animals. Researchers are responsible for following all institutional, regulatory, and biosafety guidelines when incorporating this product into experimental protocols.
Frequently Asked Questions About Bacteriostatic Water
2. How is Bacteriostatic Water used in research settings?
In research environments, Bacteriostatic Water is primarily used as a solvent or diluent for reconstituting or diluting compatible substances such as peptides and other laboratory reagents. It supports controlled preparation of solutions for in vitro assays, stability studies, and other experimental applications where repeated vial access is advantageous. Because it is formulated to inhibit bacterial growth rather than kill bacteria outright, it reduces the risk of preservative-related interference in sensitive analytical or biological systems.
3. How does Bacteriostatic Water differ from sterile water for injection?
Both products are sterile water-based solutions, but Bacteriostatic Water contains 0.9% benzyl alcohol, while standard sterile water for injection does not include a preservative. As a result, Bacteriostatic Water can typically be accessed multiple times (under appropriate storage and aseptic conditions), whereas preservative-free sterile water is generally intended for single use. This difference makes Bacteriostatic Water especially useful in research protocols requiring multiple withdrawals over a defined time window.
4. What quality parameters are important when selecting Bacteriostatic Water for laboratory work?
Researchers usually look for documented benzyl alcohol content (about 0.9%), conforming pH range, sterility, non-pyrogenicity, and compliance with relevant pharmacopeial standards. Third-party testing and clear COAs are considered important for confirming that the solution is free from microbial contaminants and meets compositional specifications. Pharmaceutical-grade manufacturing with tight process controls helps ensure consistency across batches, which is critical for reproducible experimental results.
5. Is Bacteriostatic Water safe for any type of administration?
Publicly available labeling and technical literature consistently describe Bacteriostatic Water as a diluent intended to be used only in accordance with specific product and regulatory guidance, not as a standalone injectable solution. In many official sources, it is emphasized that the solution’s role is limited to diluting or dissolving compatible substances, and it is not appropriate for direct infusion or unsupervised use. Peak Science Peptides supplies Bacteriostatic Water strictly for research purposes, and it must not be used for human or veterinary administration in any context.
