STEAM BIOLOGICAL INDICATOR 24 HOURS

Sterifirst steam biological indicators are test systems containing live microorganisms.
They are the most accurate control products in sterilisation.

Each tube contains Geobacillus stearothermophilus ATCC 7953 spores embedded in a carrier. There is also a purple growth indicator culture medium provided in an ampoule.
The Sterifirst SM20 Biological Indicator is specifically designed for monitoring vacuum-assisted steam sterilisation processes at 121-134°C and steam sterilisation processes at 121-134°C. The final reading is taken after 24 hours of incubation at 60°C.
