Description
EZTest Biological Indicators :
EZTest® is a self-contained biological indicator for monitoring steam 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.
