Chemical Indicators

The daily quality check of your sterilisation process.

Checking your temperature and time was sufficient. Easy reading of the test.

Chemical Indicators

Chemical indicators is to be used as your daily quality checkup.

Chemical indicators are easy to use, and easy to analyse. Place it in your steriliser during a run, and read the colour change when the run has completed.

The colourchange happens when the indicator has been exposed to the right temperature, expulsion, steampenetration ability, pressure and time depending on the sterilisation process. We offer chemical indicators for steam or dry heat.

oChemical indicators are class 5 and ISO 11140-1 compliant.

  • To be used daily
  • Easy to read the colour change
  • Chemical reaction indicates that the sterilisation process was started and reached the right temperature in the right amount of time

Chemical indicators are your daily quality check up

Chemical indicators are your daily quality check. For the full check of sterilisation process you need to run a biological indicator. Chemical indicators can never stand alone. If for some reason your chemical indicator fails – run a biological indicator before sending you steriliser to the mechanic.

Chemical Indicator Solutions

Chemical Indicator – Steam

Steam sterilisation (or autoclaving) is carried out by introducing saturated water vapour under pressure. In addition to the temperature effect itself, the presence of saturated water vapour is essential for killing microorganisms, their destruction being due to irreversible denaturation of cell components. Chemical indicators for autoclaves (steam)

Biological Indicator, for verification of your hygiene process

Biological indicators used to test steam sterilisation are microorganisms (spores of Geobacillus stearothermophilus, originally from ATCC 7953), prepared on filter paper as carrier material and packed in primary packaging consisting of transparent plastic film and paper which is steam-permeable.
