Chemical Indicators

The Chemical Indicators (CI) are a visual indicator to see if a product has passed through a sterilization process.

Irrad

Irrad indicators are stick on labels which are designed to demonstrate that the item has been exposed to sufficient gamma, X-ray or beta irradiation. They distinguish the difference between processed and non-processed items by a color change of the indicator. 

 

The CI comes in various shapes and forms and are designed to indicate the status of sterilization to avoid product mix-up. For example, gamma radiation exposed CI will have a red color as opposed to prior to sterilization (Yellow color).

 

Formats:

  • Round sticker

  • Meto-gun shape

  • Customized

 

Types:

 

  • Steam

  • Ethylene Oxide

  • Gamma Radiation

  • E-Beam sterilization processes

The CI can handle sterilization methods of Steam Sterilization, Ethylene Oxide (ETO), E-Beam and Gamma Radiation. For E-Beam and Gamma Radiation, high dosage (> 10kGy or >1Mrad), and low dosage ( 6-10 kGy or 0.6-1 Mrad). 

EO Gas

 

EO gas indicators are stick-on labels which are designed to demonstrate that the item has been exposed to sufficient EO gas.

 

They distinguish the difference between processed and non-processed items by a color change of the indicator. These indicators are to be used on individual items to be sterilized. The standard indicators are manufactured in different shapes (round, square or Meto shape) and some also feature text.

Steam Sterilization

 

Steam Sterilization process indicators are stick on labels which are designed to demonstrate that the item has been exposed to steam.

 

They are designed for use in steam autoclaves operating at 121°C/1 bar or 134°C/2 bar.

The indicators change color from pink to dark brown. By using steam indicators, autoclaved products can be distinguished from non-autoclaved products.
