Ensuring Purity and Safety in Every Drop

 

Water is a fundamental utility in manufacturing. Whether used for component cleaning, sterilization steam, or as a direct product ingredient, the quality of water directly impacts patient safety and regulatory compliance. Robust water quality testing is essential to prevent biofilm formation and chemical cross-contamination.
 

1. Key Testing Parameters

 

• Microbiological Analysis: Testing for Total Plate Count (TPC) and coliforms to prevent microbial excursions.

• Physical and Chemical Properties: Including pH, conductivity, and turbidity to verify the purity of the water source.

• Chemical Impurities: Monitoring for heavy metals, nitrates, and Total Organic Carbon (TOC) levels.

• Endotoxin Testing: Critical for Water for Injection (WFI) and devices contacting the cardiovascular system to ensure pyrogen-free production.
   

2. Regulatory and Industrial Context

 

• Medical Device Manufacturing: Per ISO 11737-1, processing water must be monitored to manage the bioburden of the final product.

• Sterilization Utilities: According to ISO 17665, water used for steam generation must meet specific purity standards to prevent device corrosion or sterilization failure.

• Pharmacopeia Compliance: Ensuring water meets the rigorous standards of Purified Water (PW) or Water for Injection (WFI) as defined by USP, EP, or JP.
