Chemical Indicators verify that the critical parameters of a specific sterilization cycle—such as steam, EO, or plasma—have been achieved, including temperature, exposure time, and, where applicable, saturated steam conditions.

Type 6 indicators are among the highest-level chemical indicators, designed to respond to all critical parameters of a specified sterilization cycle. However, a color change only confirms that the required physical process conditions have been met. To verify the inactivation of viable microorganisms and assess the effectiveness of the sterilization process microbiologically, Biological Indicators should be used.

The most important factors when selecting a sterilization reel are the type and size of the item to be sterilized, as well as the sterilization method to be used.

Gusset Reels provide additional internal space and are particularly suitable for bulky or thicker instrument sets. Flat Reels, on the other hand, are generally ideal for individual or flat instruments.

For both types, it is essential that the medical-grade paper and film used comply with applicable standards, including EN 868, to help ensure packaging performance and compatibility with the sterilization process.

The Bowie-Dick Test Pack is used in steam sterilizers (autoclaves) to evaluate the effectiveness of air removal and the penetration of saturated steam. It is a critical test for confirming that air has been adequately removed from the sterilizer chamber and replaced by steam.

The test should be performed daily, before the first sterilization cycle, as well as after major repairs, maintenance, or interventions that may affect the sterilizer’s performance.
