Medical Sterilization Validation | ISO 11135, 11137 & 17665
Medical sterilization validation across EtO, steam, gamma and e-beam. ISO 13485-certified facilities with in-house and managed flexibility.
Method Selection and Validation Structured to Protect Your Launch Timeline
Sterilization validation sits on the critical path of commercialization.
- Method selection.
- Bioburden Characterization.
- Cycle development.
- Packaging compatibility.
- Regulatory documentation.
Delays at this stage cascade.
LSO provides sterilization validation services across EtO, steam, gamma, and e-beam modalities, supported by in-house sterilization engineering and microbiology expertise. Validation strategy is structured to align method selection, packaging configuration, and regulatory standards from the outset.
Method Selection Matters Early
Choosing the correct sterilization modality affects:
- Device material compatibility
- Packaging performance
- Sterility assurance level (SAL) validation
- Regulatory submission strategy
- Long-term production scalability
LSO supports early evaluation of EtO, steam (including CDER-compliant applications), gamma, and e-beam sterilization pathways. Internal sterilization engineers and microbiology specialists guide modality selection based on device configuration, material composition, and commercialization objectives.
Early alignment reduces avoidable revalidation cycles and late-stage redesign.
Standards-Aligned Validation
Sterilization validation is structured around applicable international standards, including:
- ISO 11135 — Ethylene Oxide
- ISO 11137 — Radiation (Gamma & E-beam)
- ISO 17665 — Moist Heat (Steam)
- ISO 11737 — Bioburden & Sterility Testing
Validation programs address:
- Bioburden characterization
- Dose audits
- Cycle development
- Performance qualification
- Documentation traceability
All validation activity operates within an ISO 13485-certified quality system in FDA-registered facilities.
In-House & Managed Sterilization Flexibility
LSO supports both in-house and managed sterilization programs.
In-house capabilities include:
- Steam sterilization (including CDER applications)
- Small-lot EtO processing
- Multiple EtO chambers supporting capacity flexibility
Managed sterilization coordination provides access to gamma and e-beam pathways when appropriate.
This model allows validation planning to remain method-focused rather than facility-constrained.
Packaging & Sterilization Alignment
Sterilization cannot be separated from packaging validation.
Material selection, seal integrity, aging performance, and distribution simulation influence sterility assurance outcomes.
LSO aligns sterilization validation with packaging strategy to support:
- Sterile barrier system performance
- Regulatory submission continuity
- Reduced revalidation risk
- Controlled scale-up
Validation planning reflects the full manufacturing lifecycle, not isolated testing stages.
Designed for Commercial Launch and Renewal Cycles
Organizations engage LSO when:
- Preparing for initial sterilization validation
- Renewing validation cycles
- Expanding production capacity
- Addressing method uncertainty
- Seeking schedule stability
Validation programs are structured to support defined timelines and documentation clarity.
