Each biological indicator contains a population of Geobacillus stearothermophilus ATCC® 7953 spores and features an integrated chemical process indicator that changes from pink to brown when exposed to steam. The indicator is intended for routine monitoring of gravity displacement and dynamic air removal steam sterilization cycles used in dental practices, hospitals, ambulatory surgery centers, and sterile processing departments.
An optional visual confirmation can be performed after incubation. Successful sterilization cycles maintain a purple growth medium, while failed cycles produce a color change indicating viable spore growth. Key Features
