Quick and reliable Indigo® high-range 0-3000 ppm peracetic acid (PAA) test strips confirm effective concentrations for high-level medical device disinfection, ensuring patient safety and regulatory compliance.
High-level disinfection of medical devices depends on precisely maintaining strong peracetic acid solutions, often in the 1500–3000 ppm range. Indigo® 0–3000 ppm test strips are designed to verify that the concentration of peracetic acid remains sufficiently high to achieve the required sporicidal and bactericidal efficacy. Unlike low-range strips used for rinse verification, these strips ensure that the disinfectant solution itself meets validated disinfection thresholds. This simple, rapid check reduces the risk of under-concentration and provides peace of mind for sterile processing and infection control teams.
Hospitals, ambulatory surgical centers, and reprocessing facilities can use these peracetic acid test strips to support high-level disinfection protocols for endoscopes, surgical instruments, and other reusable devices. Confirming ≥1500 ppm peracetic acid in active solutions not only safeguards against microbial survival but also helps document adherence to infection prevention guidelines. Reliable strip-based testing allows healthcare workers to quickly validate disinfectant strength without the need for complex instrumentation.
