Steam-Biological Indicator
This product uses Geobacillus stearothermophilus (ATCC7953) as the indicator organism. It consists of a spore strip, recovery medium (sealed in a glass tube), and a plastic outer shell. It detects the survival of spores via fluorescent technology, allowing a sterilization result to be obtained within 3 hours to determine whether the steam sterilization cycle was successful.
The spore content is ≥1.0×105 cfu per unit. At 121°C ±1 saturated steam, the D value is ≥1.5 minutes.
Suitable for monitoring the effectiveness of 132°C and 134°C pressure steam sterilization processes.
1. Positive (Red Light / "+"): Sterilization failure.
2. Negative (Green Light / "−"): Sterilization success.
3. Positive Control: Must show a fluorescence positive result for the test to be valid.
