Steam chemical indicator strip Comply

The 3M Comply 1250 Type 4 Chemical Indicator Strip is designed for monitoring steam sterilization. Its indicator ink changes from off-white to black when exposed to the steam sterilization process, showing steam penetration where the strip is placed. Suitable for gravity and vacuum-assisted cycles from 121°C to 134°C (250°F to 273°F), each strip measures 1.5 cm x 20 cm (0.625 in x 8 in). A center perforation allows easy shortening when a smaller internal indicator is preferred. Box includes 240 strips for high-throughput sterilization monitoring.
