Fh-Value

The Fh value, often referred to as the heat penetration factor in the context of dry heat sterilization, is an important parameter for evaluating the efficiency and effectiveness of the sterilization process. Unlike moist heat sterilization, which typically uses steam at 121.1°C, dry heat sterilization employs higher temperatures. The Fh value quantifies the time and temperature necessary to achieve a specific level of microbial reduction under these conditions.
