STERIS Steraffirm? Steam Type 6 Emulating Indicators are cycle verification indicators that confirm the presence or absence of specific time and temperature parameters during a cycle, and integrate all the critical parameters of the steam sterilization cycle (temperature, saturated steam and exposure time). Emulating indicators can be placed inside each pack or pouch during sterilization of supplies or equipment in a validated pre-vacuum cycle. These emulating indicators can be used for routine monitoring of steam sterilization cycles. Steraffirm Type 6 Emulating indicators are non-toxic and free of lead or heavy metals.
