Built around the clinical workflow
- Self-contained rapid readout biological indicators
- Readout from 5 minutes to 24 hours, depending on model
- Geobacillus stearothermophilus ATCC 7953 or Bacillus atrophaeus ATCC 9372
- Population ≥1.0 × 10^6 CFU per strip
- 50 indicators per box
- Compatible with UG-AR series Auto Readers and UG-AI series incubators
UGAIYA rapid readout biological indicators are self-contained systems for release control and validation of steam, VH2O2, EO, formaldehyde, dry heat and water-bath sterilization. The closed design protects the spore strip and culture medium, reduces handling contamination and gives a clear fluorescence result when used with a UG-AR series reader.

Model selection
| Application | Models | Organism | D-value | Readout |
|---|---|---|---|---|
| Steam | UGBI0301 / 0101 / 0201 / 0206 / 0207 / 0501 | G. stearothermophilus | ≥1.5 min at 121 °C | 5 min–24 h |
| VH2O2 | UGBI0102 / 0107 / 0108 / 0502 | G. stearothermophilus | ≥1 s at 50 °C, 5 mg/L | 1–24 h |
| EO | UGBI0401 / 0402 / 0403 / 0503 | B. atrophaeus | ≥2.5 min at 54 °C, 600 mg/L | 5 min–24 h |
| Formaldehyde | UGBI0103 / 0104 / 0105 / 0505 | G. stearothermophilus | ≥2.5 min at 54 °C | 20 min–24 h |
| Dry heat | UGBI0504 | G. stearothermophilus | ≥2 min at 160 °C | 24 h |
| Water bath | UGBI0506 | G. stearothermophilus | ≥1.5 min at 121 °C | 24 h |
Why self-contained indicators
- Closed indicator design reduces the risk of cross infection during handling and incubation
- Standardized spore population and D-value support reproducible sterilization validation
- Fast readout helps release every load with confidence and reduce instrument turnaround time
- Works with the UG-AR series Auto Reader for automatic recognition, countdown and printed reports
For 24–48 hour conventional biological indicators, use the UG-AI series incubator. For rapid readout, pair with the UG-AR series Auto Reader. Confirm the correct indicator model against the sterilization cycle and your local policy.
