Pharmaceutical-Grade
Passivation Services
Complete IQ/OQ/PQ validation packages with FDA audit-ready documentation. Protecting bioreactors, WFI systems, and process equipment.
Why Passivation Is Critical
Untreated stainless steel surfaces harbor risks that can compromise product integrity and fail regulatory audits.
-
Bioburden & Contamination
Surface irregularities trap microorganisms that survive standard CIP cycles.
-
Rouge Formation
Iron oxide contamination develops on improperly passivated surfaces.
-
Regulatory Issues
FDA 483 observations frequently trace back to inadequate surface preparation.

System Showing Rouge?
Rouge contamination compromises product purity and signals underlying passivation failure. Our derouging process restores surfaces to pristine condition.
⚠️ Signs You Need Derouging
- Pink/red discoloration in WFI
- Iron particles in filters
- Elevated iron readings
- Surface staining on welds
