Healthmark EZTest Biological Indicators - 100 Per Pack

EZTest is a self-contained biological indicator for monitoring (#BI-1) steam or (#EZG-6) ethylene oxide 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 48 hours without laboratory transfers.

Simply place EZTest inside products or product packages to be sterilized. The “inoculated package” is then placed in the sterilizer and processed. Upon removal from the sterilizer, the EZTest BI is “activated.” Using a crushing device, flex the sides of the soft plastic culture tube to break the glass ampoule to allow the medium to mix with the spores. The “activated” EZTest BI is then placed in an appropriate incubator for 48 hours. If any spores survive the process, the medium will turn yellow.
