Description

Multi-variable Chemical Indicator printed with reactive ink for Steam sterilization processes.

Chemdye® CD29 Multivariable Process Indicators (Type 4 according to ISO 11140-1:2014 standard) are single-use chemical indicators that consist of one-side laminated punched paper double strips printed with indicator ink. These indicators have been designed to monitor Steam sterilization processes within loads, ensuring an adequate exposure to the sterilizing agent during the sterilization process and allowing to distinguish between processed and unprocessed items.

Innovative highly sensitive yellow ink was developed to turn to dark brown/black when the indicator is exposed to Steam considering the critical process variables which provides additional quality assurance. Endpoint condition: 121 °C, 15 minutes; 134 °C, 3.5 minutes. Indicators 100 % free of toxic heavy metals.

Instructions for Use

1. Place a Chemdye® CD29 Multivariable Process Indicator within each package, bag or tray that will be sterilized by Steam. In rigid containers, place the indicator in every corner, or at least two diagonally opposite corners, to ensure that the sterilization agent has reached the most inaccessible areas.

2. Perform the sterilization cycle.

3. After the sterilization process has finished, remove the indicators from the sterilizer and analyze the results. For all the chemical indicators exposed to Steam, the ink must turn to the dark brown/black reference color when the sterilization parameters are reached. For reference color, please refer to Result Reference Guide.
