If your finished medical device has an endotoxin limit of 20 EU/device, what limit should you set for each component? If every component has the full device limit, their combined endotoxin level could exceed it. An equal medical device component split may seem straightforward, but it can overlook important differences in materials, processing, and patient exposure. Start by understanding how much endotoxin each component may contribute and how you control it. ISO 11737-3:2023

Introduction Biological indicators (BIs) are widely recognized as the gold standard for monitoring the effectiveness of sterilization processes. Following exposure, BIs are incubated to allow any surviving microorganisms to recover and grow. Traditionally, international standards have defined seven days as the reference incubation period for established sterilization processes such as moist heat (steam) and ethylene oxide (EO). However, advances in spore production, culture
