OPERATING
CYCLE EXAMPLE
The Millennium B² sterilization program can be described as a succession of phases, each
with a specific purpose.
For example, after loading the material in the chamber, closing the door, selecting the program
and starting the cycle (and the consequent locking of the door opening mechanism), the
standard program (for porous materials, 134 °C - 4’) offers the following sequence (see chart,
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.
After reaching atmospheric pressure, the door is automatically unlocked and it can be opened
to remove the load from the sterilization chamber.
It should be emphasized that 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 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.
