The Classic series sterilisation programme can be effectively described as a succession of pha-
ses, each one with a very precise objective.
For example, the universal program (cycle B, 134°C - 4’): after loading the material in the cham -
ber, closing the door, selecting the program and starting the cycle (after locking the door opening
mechanism), the following sequence will be suggested (see the graph below):
1. preheating the generator and sterilization chamber;
2.
removing the air and penetration of the material by steam through a series of vacuum (extraction
of the fluid from the sterilization chamber) and pressure(injection of steam into the chamber)
phases;
3. raising the pressure, with the consequent increase in the temperature of the steam, until reaching
the conditions required for sterilization (in the example, 134 °C );
4. stabilizing the pressure and temperature;
5.
sterilizing for the required time (in the example, 4 minutes );
6. depressurizing the sterilization chamber;
7. vacuum-drying phase;
8. ventilating the load with sterile air;
9. bringing the pressure of the sterilization chamber back to the atmospheric level.
having reached this last phase, you can unlock the door and remove the load from the steriliza-
tion chamber.
It should be emphasized that phases 1, 3, 4, 6 and 9 are identical in all cycles, with slight varia-
tions of duration that are solely dependent on the quantity and consistency of the load and the
heating conditions of the sterilizer while phases 2, 5, 7 and 8 clearly vary their configuration and/
or duration on the basis of the cycle selected (and, as a consequence, the type of load) and the
choices made by the user.
