Working principle
The sterilisation cycle consists of raising the chamber temperature to a desired value and keeping it for an
established period of time.
It is possible to set the temperature value, bearing in mind that there is a correlation between temperature and
pressure. Note that the autoclave is equipped with a pressure gauge which shows pressure measured in bar
units.
The correlation between temperature and pressure in this autoclave is as follows:
121 °C - 1,03 bar
134 ° C - 2,0 bar
Heating operation produce steam which helps air evacuation. The autoclave is equipped with an electro valve
that automatically closes when the air contained in the vessel has been discharged.
When the total sterilisation cycle is completed an acoustic alarm will advise the operator; once the alarm rings
the chamber starts its cool down operation.
