CD20 / Multi-variable Chemical Indicator, strips printed with reactive ink for Steam sterilization processes.

Chemdye® CD20 Multivariable Indicators have been designed to react to Steam sterilization processes within loads, ensuring an adequate control of the effectiveness of sterilization processes (temperature, time and steam quality).

Chemdye® CD20 Multivariable Indicators have been manufactured with an innovative ink tecnology, highly sensitive to steam quality and air presence within the load.

The purple ink was developed to turn to green when the process reaches the stated values of the critical process variables.

Multivariable indicators allow to rapidly detect whether the critical parameters of the sterilization process for which they have been designed to respond have been reached. Endpoint conditions: 121 °C, 15 minutes // 134 °C, 3.5 minutes.

Instructions for use

– Place a Chemdye® CD20 Multivariable 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.

– After completing the process, analyze results. The indicator must turn to the reference color for considering that the indicated conditions were met.
