EZTest is a self-contained biological indicator for monitoring steam / flash steam, ethylene oxide, or hydrogen peroxide sterilization. EZTest contains bacterial spores on a filter-paper carrier packaged within a small, thermoplastic culture tube. Inside the thermoplastic culture tube is a sealed-glass ampoule of specially-formulated soybean casein digest culture medium containing a color indicator which turns a dramatic yellow when spores grow. EZTest is easy-to-use and produces visual results within 24 hours (steam or hydrogen peroxide) or 48 hours (ethylene oxide) without laboratory transfers.
- 24 hour results for steam or H2O2
