Frequently Asked Questions

Your Questions about Sterilization Indicator Inks

Which sterilization processes do you manufacture indicator inks for?

We offer indicator ink solutions for steam, ethylene oxide (EO), hydrogen peroxide (H₂O₂), formaldehyde and plasma sterilization processes.

How does sterilization indicator ink work?

Indicator ink is developed to produce a distinct colour change when exposed to the relevant sterilization process. This change helps visually identify whether a product has been exposed to the sterilization process.

Which surfaces can indicator inks be applied to?

Formulations can be developed for medical kraft paper, suitable medical films and other printing surfaces used in sterilization packaging.
