Chemical Indicators

DIN EN ISO 11140-1

Chemical Indicators are being used for daily controls as well as validation of sterilisation processes. There is a broad variety of Chemical Indicators, which are developed particularly for the different existing sterilisation methods.

Chemical Indicators are classified within DIN EN ISO 11140-1.
In our BIER-Vessel or in the dry heat sterilisator, we are able to classify if the Chemical Indicator that is used in your process complies with ISO 11140-1.

We may verify the following classes of Chemical Indicators:

  • class 1 (process indicators)
  • class 3 (single variable indicators)
  • class 4 (multivariable indicators; on the basis of ISO)
  • class 5 (steam integrating indicators; on the basis of ISO)
