A method for pressurizing a sterilization chamber of a steam sterilizer with a controlled rate of pressure change. Pressure is increased in the sterilization chamber by opening a steam- to-chamber valve for a pulse duration during each of a plurality of time PERIODS needed to reach a target pressure value. During each time PERIOD, the steam-to-chamber valve is moved to an open state for the duration of the pulse. An error value indicative of the difference between a Theoretical Pressure and a Measured Pressure is determined at the end of each PERIOD. This error value is used to determine the duration of the pulse for the subsequent PERIOD, thereby maintaining a desired rate of pressure change in the sterilization chamber.

An air removal test system for verifying adequate air removal during a sterilization cycle of a pre-vacuum type sterilizer includes specimen holder and a test strip. The test strip includes a solid indicator chemical, which liquefies and travels along a wicking element during the sterilization cycle. The test strip is configured to verify adequate removal of air during the sterilization cycle by displaying a color change through a window.
