Medical device sterilization validation with timeline certainty and proven compliance

Method selection depends on your device materials, geometry, packaging, and regulatory requirements. EtO is the most common for temperature-sensitive devices but has longer cycle times and aeration requirements. Gamma and e-beam offer faster turnaround and no residuals but can degrade some polymers. Steam is suitable for heat-stable metal instruments. During our method selection consultation, we evaluate your device against all five methods and recommend the best fit based on material compatibility, timeline, and cost.

A typical first-time sterilization validation takes 12–20 weeks from method selection through PQ completion. This includes bioburden testing (2–3 weeks), protocol development (1–2 weeks), IQ/OQ (3–4 weeks), and PQ with product-loaded runs (4–6 weeks). If you already have bioburden data and a defined method, the timeline compresses. We provide a detailed timeline during the initial consult so there are no surprises.

IQ (Installation Qualification) verifies that sterilization equipment is installed correctly and meets specifications. OQ (Operational Qualification) proves the equipment operates within defined parameters — temperature, humidity, gas concentration, exposure time — without product. PQ (Performance Qualification) is the final phase: product-loaded runs that demonstrate the sterilization process consistently achieves the required Sterility Assurance Level (SAL) under actual production conditions. All three phases are required for a complete validation.

Yes — method transitions are one of the most common reasons companies come to us. We handle the full scope: material compatibility assessment for the new method, dose setting studies, validation protocol development, and IQ/OQ/PQ execution. Because we run validation programs across all five methods — EtO and steam in our facilities, gamma, e-beam, and VHP through qualified partners — you're working with one validation team throughout the transition instead of finding and managing a new sterilization provider yourself.

Pre-validation bioburden testing per ISO 11737-1 establishes the microbial load on your device, which directly informs dose setting for radiation methods and cycle development for EtO. We recommend a minimum of three bioburden lots from representative production to establish a baseline. If your bioburden data is outdated or from a different manufacturing environment, we'll need fresh samples. This testing typically takes 2–3 weeks and should start as early as possible to avoid delaying validation.

Yes. For EtO and steam, we provide ongoing production sterilization in our facilities — routine processing, biological indicator testing, and certificate of sterilization for each lot. For gamma, e-beam, and VHP, we coordinate ongoing production processing and dose audits through the same qualified partners that supported your validation. Either way, validated parameters carry directly into routine operations without re-qualifying a different sterilization provider.

You receive a complete sterilization validation report package including: method selection rationale, bioburden test reports, material compatibility data, IQ/OQ/PQ protocols and reports, dose setting or cycle development data, and a validation summary report. Everything is formatted for FDA 510(k), EU MDR technical file, or other regulatory submissions. Our documentation has supported hundreds of successful submissions across multiple regulatory bodies.

Most sterilization validations require periodic requalification to stay compliant. For radiation methods under ISO 11137, you need a quarterly dose audit and a full revalidation if you change product, packaging, or load configuration. For EtO under ISO 11135, revalidation is triggered by process changes or whenever your ongoing controls fall outside established limits — typically every 2 years for routine programs. We manage requalification and revalidation programs end-to-end, so your sterilization process stays continuously qualified instead of lurching from one expiration to the next.
