SAMPLE
OPERATING
CYCLE
The Bravo’s sterilization program is a succession of phases, each with a specific purpose.
After loading the material in the chamber, closing the door, selecting the program and starting
the cycle (the door opening mechanism locks automatically), the standard program (for porous
materials, 134 °C at 4 minutes, for example) uses the following sequence:
1. Preheats the generator and sterilization chamber;
2. Removes the air and penetrates the material by steam through a series of vacuum
(extracting fluid from the sterilization chamber) and pressure (injecting steam into the
chamber) phases;
3. Raises the pressure, with the consequent increase in the temperature of the steam, until
reaching the conditions required for sterilization (for example, 134 °C);
4. Stabilizes the pressure and temperature;
5. Sterilizes for the required time (for example, 4 minutes);
6. Depressurizes the sterilization chamber;
7. Begins vacuum-drying phase;
8. Ventilates the load with sterile air;
9. Brings the pressure of the sterilization chamber back to the atmospheric level.
After reaching atmospheric pressure, the door is automatically unlocked and can be opened to
remove the load from the sterilization chamber.
Phases 1, 3, 4, 6 and 9 are identical in all cycles, with slight variations of duration that are
solely dependent on the quantity and consistency of the load and the heating conditions of the
sterilizer. Phases 2, 5, 7 and 8, however, vary their configuration and/or duration on the basis
of the cycle selected (and, consequently, the type of load) and the choices made by the user.
