Bacteriostatic Water (3ml & 10ml)

Bacteriostatic Water is sterile water containing 0.9% benzyl alcohol as a preservative, designed for reconstituting lyophilized research peptides, formulated and packaged in the USA. Each batch undergoes sterile filtration and quality verification, with independent third-party testing confirming sterility and pH compliance. Supplied for laboratory research use only.

Studies of Bacteriostatic Water (3ml & 10ml) typically combine purity verification with functional assays to support reproducible results.

Researchers evaluating Bacteriostatic Water (3ml & 10ml) document batch COA data and storage conditions as part of experimental design.

Bacteriostatic Water (3ml & 10ml) is often included in comparative panels alongside related peptides to characterize research utility.

This product is available in 3ml and 10ml. Each vial contains lyophilized peptide at the labeled quantity; wholesale orders are packed in boxes of ten vials at a single per-vial price.

Quality assurance: every batch is purified by reversed-phase high-performance liquid chromatography and identity-confirmed by mass spectrometry, with purity above 99%. Lot-specific certificates of analysis are available on request. Store lyophilized vials at -20°C, protected from light and moisture; reconstitute with bacteriostatic water immediately before use and avoid repeated freeze-thaw cycles. For in-vitro laboratory research use only — not for human or veterinary use.

Research & Literature

The following peer-reviewed studies and reference documents are commonly consulted by researchers working with Bacteriostatic Water (3ml & 10ml). Summaries are provided for orientation only and reflect the cited sources.

Antimicrobial Preservative Use in Parenteral Products: Past and Present^[1] — This review examined the historical and current use of antimicrobial preservatives, including benzyl alcohol, in multidose parenteral products. It discussed the regulatory and safety considerations governing preservative selection and concentration. The authors provided context relevant to products such as bacteriostatic water used for reconstitution and dilution of injectables. (Journal of Pharmaceutical Sciences 2007)

Benzyl alcohol: toxic agent in neonatal units^[2] — This editorial warned about the toxicity of benzyl alcohol when used in neonatal units, describing adverse effects associated with its presence in flush and diluent solutions. The report contributed to safety awareness and the establishment of concentration limits for benzyl alcohol in injectable products. It remains a key reference for understanding the safety context of preservatives in parenteral formulations. (Pediatrics 1983)

Antimicrobial Preservatives for Protein and Peptide Formulations: An Overview^[3] — This overview examined antimicrobial preservatives used in multidose protein and peptide formulations, including compatibility and stability considerations. It discussed how preservatives such as benzyl alcohol can affect the stability of biologic drug products. The review provided guidance relevant to the formulation of diluents such as bacteriostatic water. (Pharmaceutics 2023)
