Process Challenge Devices

Process Challenge Devices

A Process Challenge Device (PCD) is the surrogate of product used for microbiological monitoring of both, validation and routine sterilization cycles. It consists of a biological indicator within a specific configuration such as syringes, tubing, etc., that poses an increased resistance to represent a stringent challenge to the sterilization process.

NLI produces different configurations of PCDs designed with consideration to the various sterilization parameters. Their composition is based on different resistance levels to adapt to different cycle specifications.

Study Outline

PCDs are prepared by placing a biological indicator (BI) of known resistance inside a specific configuration such as syringes, tubing, etc. Each device represents a different degree of resistance that is greater than the BI alone. The PCD is then placed in a tyvek pouch and sealed for containment. Each PCD is labeled with the lot number and expiration dates of the BI, as well with its brand name. In addition, each label contains a chemical indicator that changes color after exposure to EO for easy traceability and indication of cycle processing.
