EZTest® Steam Biological Indicator
G. stearothermophilus, 24-Hour Incubation at 57ºC – 25 Vials/Pkg

The Mesa Labs EZTest® Biological Indicator is a self-contained BI for monitoring sterilization of solid loads, suitable for use in steam, ethylene oxide, propylene oxide, or hydrogen peroxide sterilizers. This steam-specific vial uses G. stearothermophilus spores on a filter-paper carrier, packaged within a small thermoplastic culture tube, and produces dramatic visual results within 24 hours at 57ºC.

Inside each vial is a sealed-glass ampoule of specially formulated soybean casein digest culture medium containing a pH colour indicator, which turns a dramatic yellow when spore growth occurs. EZTest® is easy to use in-office, requiring no laboratory transfer, making sterilization monitoring straightforward for clinical and dental settings.
