PRIMA Class 4 Steam Chemical Indicator Double Strip (Emulator) 134°C, 3.5 min, 250 pcs

The PRIMA Class 4 Steam Chemical Indicator Double Strip (Emulator) is designed for precise monitoring of key parameters during steam sterilization cycles in autoclaves. It provides a reliable internal chemical indication of exposure to the required time, temperature, and steam saturation conditions within each sterilization package or tray. Class 4 indicators are multiparameter devices that react simultaneously to two or more critical variables, such as time and temperature, ensuring that the sterilization process meets the required conditions. The PRIMA indicator is calibrated to operate under standard steam sterilization parameters of 134°C for 3.5 minutes, ensuring accurate performance in medical and laboratory environments. Each double strip has a size of 200×15 mm, allowing convenient placement inside pouches, wraps, or trays. After the sterilization cycle, the indicator changes color to visually confirm exposure to the appropriate steam and temperature levels, enabling easy interpretation of results. • Size: 200×15 mm (double strip). • Operating conditions: 134°C - 3.5 minutes. • Chemical composition: - Isopropyl acetate 15-20% (CAS #108-21-4). - Isopropyl alcohol 15-20% (CAS #67-63-0). - Glycol ether 1-5% (CAS #107-98-2). - Lead carbonate 15-20% (CAS #1319-46-6). - Barium thiosulfate 5-10% (CAS #35112-53-9). The chemical formulation is stable and does not contain substances classified as hazardous under EU directives. Each indicator is printed in a rectangular format and is sensitive to changes in temperature, time, and steam concentration, ensuring consistent and reproducible color development. To use, place one indicator strip inside each sterilization package, bag, or tray before running the steam sterilization cycle. After exposure, visually check the strip for the expected color change, confirming that the load was subjected to proper sterilization conditions. Each box contains 250 printed double strips that serve as internal chemical monitors for steam sterilization cycles. The PRIMA indicators are suitable for professional use in medical practices, dental offices, laboratories, and beauty centers that rely on steam autoclaves for instrument sterilization. This product provides clear and reliable chemical evidence of exposure to the defined sterilization parameters, supporting effective control and documentation of autoclave performance.
