Description:
Sterile Water for Injection (WFI) is a high-purity, pyrogen-free solvent specifically designed for parenteral-grade applications, including the reconstitution of lyophilized peptides, biologics, and injectable research compounds. It meets or exceeds USP, EP, and JP pharmacopoeial standards, ensuring the absence of endotoxins, microbial contaminants, and particulates. Unlike bacteriostatic water, WFI contains no preservatives, making it ideal for single-use, sterile environments where absolute purity is required.

⚙️ Functional Role in Research:
• Solvent for Peptide Reconstitution: Ideal for peptides that are sensitive to preservatives or require neutral pH
• Parenteral-Grade Purity: Free from endotoxins and microbial contaminants
• Single-Use Applications: Preferred for sterile, one-time reconstitution protocols
• Carrier for Dilution: Used in formulation of injectable research compounds and biologics
---
📈 Research Applications:
Sterile WFI is widely used in:
• Peptide and protein reconstitution
• Cell culture and biologic formulation
• Vaccine and mRNA research
• Final rinse for sterile equipment and vials
• Analytical chemistry workflows requiring pyrogen-free solvents
Its non-reactive, preservative-free profile makes it suitable for sensitive peptides like IGF-1 variants, GHK-Cu, and neuropeptides.
