Process Challenge Devices® (PCD®)
Process Challenge Devices® (PCD®) certified to ISO 13485 quality systems for medical devices. Available across 6 resistance types, these PCDs ensure success of terminal sterilization cycles of medical devices, and can be used for both validation and routine monitoring of EO sterilization cycles.
Each PCD combines specific biological indicators with proprietary barrier pouches to achieve consistent, validated resistance levels for ethylene oxide (EO) sterilization, plus one specialized option for hydrogen peroxide (H₂O₂) sterilization.
Why choose Mesa Labs PCDs?
- Each PCD has a defined resistance value, with all components resistance tested using an ISO 18472 compliant resistometer, ensuring complete confidence in every PCD.
- Manufactured under an ISO 13485 certified quality system
- Helps to achieve compliance with ISO 11135.
- Patented packaging of a variety of B. atrophaeus biological indicators (BI) to match your process.
- Broad resistance levels and BI types to meet different cycle configurations.
- Faster turnaround with self-contained biological indicators (SCBI).

Selecting the correct resistance level
Not sure which PCD® is right for your cycle? Mesa’s PCD Selection Set includes four of the most common resistance configurations in one kit, helping you quickly determine the correct match.
