Hospira Bacteriostatic water 30ml

What is Pfizer Hospira™ Bacteriostatic Water?

Pfizer Hospira™ Bacteriostatic Water for Injection, USP is a sterile, non-pyrogenic water preparation containing 0.9% benzyl alcohol (v/v) as a preservative. Manufactured under stringent pharmaceutical-grade standards by Hospira, a Pfizer company, this solution is intended for use as a reconstitution medium for peptides and proteins in in vitro research. Its bacteriostatic properties inhibit microbial growth in multi-use vials, making it ideal for laboratories requiring repeated access to reconstituted peptide solutions.

Key Composition

• Water: USP Sterile Water for Injection
• Preservative: Benzyl Alcohol 0.9% (v/v)
• Manufacturer: Hospira Inc., a Pfizer company
• pH Range: Typically 4.5–7.0
• Osmolarity: Hypotonic
• Sterility: Confirmed sterile and non-pyrogenic (USP standards)

Benefits for In Vitro Peptide Research

• Multi-Dose Convenience: Supports multiple withdrawals from a single vial under sterile lab conditions, reducing waste and maximizing resource efficiency.
• Preservation of Reconstituted Peptides: Benzyl alcohol inhibits bacterial growth, helping maintain peptide integrity for up to 28 days when stored appropriately.
• Pharmaceutical Manufacturing Standards: Pfizer Hospira™ branding guarantees consistency, purity, and sterility that meets stringent quality assurance criteria.
• Broad Compatibility: Effective for reconstitution of a wide array of synthetic peptides, including growth factors, GHRH analogs, and bioregulators.

Common Research Applications

• Peptide and protein reconstitution prior to dilution in assay buffers.
• Short-term storage of working peptide solutions used in metabolic, signaling, and receptor-binding assays.
• Repeated use scenarios where multiple experiments require access to a single reconstituted batch.
• Tissue culture supplementation (when validated for benzyl alcohol tolerance).
• Molecular and biochemical analyses involving rehydrated synthetic peptide standards.

Guidelines for Use

• Use under aseptic conditions to avoid contamination.
• Ideal for laboratory settings where peptide solutions are stored refrigerated for 7–28 days post-reconstitution.
• Not recommended for cell types or enzymes highly sensitive to benzyl alcohol—validate compatibility before use.
• Always store reconstituted peptides in labeled, sterile vials at 2–8 °C.
