3. PRODUCT INTRODUCTION

OPERATING

CYCLE EXAMPLE

The Millennium series sterilisation programme can be effectively described as a succession

of phases, each one with a very precise objective.

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.
