Our Chemical Indicators and Biological Indicators
Chemical Steam Indicators
Chemical steam indicators can be used in steam sterilization processes. They show a significant colour change from pink (unexposed) to dark brown, when exposed to steam. Chemical steam indicators are designed for use in steam autoclaves operating at 121 °C / 1 bar or 134 °C / 2 bar. The colour change of the indicators is dose dependent. The indicators are meant to be used on individual items that need to be sterilized. The indicators can be supplied as single dots, squares or other shapes They can be printed or applied to larger labels that are preprinted or customized with text or company logo.
Biological Steam Indicators
Biological steam indicators are carriers with spores of geobacillus stearothermophilus, as a challenge to the sterilization process. They are used for validation and routine monitoring to demonstrate the efficacy of the sterilization cycles. The indicator is exposed to the process and then incubated under defined growth conditions to determine whether any spores survived the process. If no spores survive, none grow and the cycle is a pass. If growth is detected, it is a fail. All Etigam biological indicators rely on true and full microbial growth. A dedicated reader is not required, the result can be visually verified (by colour-change or turbidity).
