Chemical Indicator Test Strips

Excelsior Chemical Process Indicator Strips are suitable for application of various types of sterilisation including steam, dry Heat, Hydrogen peroxide, ethylene oxide & formaldehyde.

The strip indicator colour demonstrates at a glance whether or not the product has gone through the sterilisation process, making it easy for sterilisation facilities to ensure that products have been exposed correctly to the sterilisation process. Strips transition an initial colour to a different signal colour depending on the process type.
