Chemical Indicators (CI)

The Chemical Indicators (CI) are a visual indicators to see if a product has passed through a sterilization process. These indicators are stick on labels that can be easily applied to the product.

​​

The CI comes in various s shapes and forms and are designed to indicate the product status of sterilization to avoid product mix-up.

​

Types of CI: 

​

• Steam

• Ethylene Oxide (EO)

• Gamma Radiation

• E-Beam Sterilization Processes

​

Irradiation (IR)

​

IR indicators 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. For example, gamma radiation exposed CI will have a red color as opposed to prior to sterilization (Yellow color). For E-Beam and Gamma Radiation, high dosage (> 10kGy or >1Mrad), and low dosage (6-10 kGy or 0.6-1 Mrad) stickers are available.

 

Formats:

​

• Round Sticker

• Meto-Gun Shape

• Customized

​

EO Gas

 

EO gas indicators are designed to demonstrate that the item has been exposed to sufficient EO gas.

 

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 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.
