Autoclaves use a combination of mechanisms to regulate steam generation and maintain pressure.

1. Generation of Steam and Temperature Increase:

The autoclave converts electrical energy into heat energy.

This heat energy is used to heat water within the chamber.

As the water reaches its boiling point, it produces steam.

The accumulation of steam inside the chamber increases the pressure.

This increase in pressure raises the boiling point of water above 100°C.

This allows the temperature inside the autoclave to reach sterilization temperatures, typically between 121°C to 134°C.

2. Control and Maintenance of Temperature:

Modern autoclaves are equipped with sophisticated control systems.

These systems monitor and adjust the temperature and pressure during the sterilization cycle.

Sensors detect internal conditions and adjust the heating elements accordingly.

If the temperature drops below the required level, the control system activates the heating elements to increase the temperature.

Conversely, if the temperature exceeds the set point, the system reduces the heat input to prevent overheating.

3. Thermostatic Traps:

A critical component in temperature control is the thermostatic trap or steam trap.

This device allows air and condensate to escape from the chamber while preventing the escape of dry steam.

The trap operates based on temperature; it closes when heated past a certain setpoint.
