Turns to green or darker.

ETHYLENE OXYDE STERILIZATION INDICATOR

Chemical indicators Type 1 multiparameter (EN-ISO 11140-1:2014).

• initial colour: yellow/orange.
• Final colour: green.
• Process parameters: ethylene oxyde and proper relative humidity .

CHARACTERISTICS

Our Visto Bueno®sterilization indicators for Ethylene Oxyde processes have been designed to check that the sterilization processes have been correctly achieved.
Introduce one indicator within the package to be processed.In big packages more than one indicator might be needed, placed in different locations .
After the sterilization process ,the round yellow/orange indicator will turn to Green or darker compared to the colour showed in the standard. Because the sterilization with ethylene oxyde depends deeply on percentages of humidity, temperature and concentration of the gas, there can be a wide range of final colours in the shade of green . The initial yellow colour will remain unchanged if one or more of the sterilization parameters have not been achieved.
