The McKesson Steam Sterilization Chemical Indicator Strips (Class 4) offer a visual monitoring solution to ensure the effectiveness of steam sterilization processes within healthcare facilities. These single-use strips comply with Class 4 requirements for steam sterilization cycles. They are designed for use in steam sterilizers operating at temperatures between 250-285 degrees Fahrenheit (121-140 degrees Celsius). The indicator strip undergoes a clear color change from blue to black when exposed to steam sterilization conditions, providing immediate and easy-to-read confirmation of successful sterilization. This visual verification helps to ensure patient safety and regulatory compliance.
