Abstract

There is provided a device (10) for monitoring sterilization of a material with steam comprising at least one layer (20), composed of polymeric binder (21), having incorporated therein an isomeric indicator (22) capable of undergoing at least one color change and optionally, a controller (23) for said indicator capable of influencing the time and temperature required for said color change when contacted with steam.
