EZTest Biological Indicators are designed to monitor a wide range of sterilization processes, including steam, flash steam, ethylene oxide, and hydrogen peroxide. Each unit contains a carrier inoculated with spores and a sealed ampoule filled with growth medium that changes color when microbial growth occurs. Steam and EO versions use a filter paper carrier, while hydrogen peroxide versions use a stainless-steel disc for added durability. With results available in 24 hours for steam and H2O2, or 48 hours for EO, EZTest offers quick feedback without requiring laboratory transfers. Its simple workflow, dramatic color change, and reliable detection support consistent sterility assurance.
