An autoclave works by using the principle of moist heat sterilization.
This involves high pressure and steam to sterilize equipment.
The high pressure inside the autoclave increases the boiling point of water.
This allows for rapid heat penetration into the deeper parts of the equipment.
The heat, combined with moisture from the steam, causes protein coagulation in microbes.
This leads to their irreversible loss of activity and functions.
Effectively killing them and sterilizing the equipment.
How Does an Autoclave Work Inside? 4 Key Steps Explained
1. Principle of Moist Heat Sterilization
The autoclave operates on the principle of moist heat sterilization.
This is more effective than dry heat because water transfers heat more efficiently.
This efficiency allows for a lower temperature to be used for sterilization.
Typically between 100 to 134°C.
2. Conversion of Electrical Energy to Heat Energy
The autoclave converts electrical energy into heat energy.
This thermal energy is directed into the water within the chamber.
Causing it to boil and produce steam.
The steam then accumulates, increasing the pressure inside the chamber.
3. Displacement of Air and Control of Temperature and Pressure
As the steam is produced, it displaces the air inside the chamber.
The temperature and pressure are continuously monitored and adjusted.
To maintain the optimal conditions for sterilization.
This process ensures that the environment inside the autoclave is conducive to killing microbes.
4. Cyclic Phases of Sterilization
The sterilization process in an autoclave involves three main phases:
Purge Phase: Steam flows through the sterilizer, displacing air. The temperature and pressure gradually increase.
Sterilization Phase: The chamber is maintained at the required temperature and pressure for a specific duration to ensure all microbes are killed.
Exhaust Phase: After the sterilization cycle is complete, the steam is exhausted, and the chamber is cooled and depressurized before the equipment can be removed.
5. Operation of the Autoclave
Operating an autoclave involves several steps:
Checking the chamber for any residual instruments.
Adding the appropriate amount of water to the chamber.
Placing the instruments inside.
Sealing and securing the chamber, then activating the electric heater.
Adjusting safety valves to maintain the required pressure.
Allowing steam to displace all air inside the chamber.
Closing the drainage pipe and allowing steam to reach the desired level.
Running the autoclave for the set time period.
6. Role of Steam Generator and Wastewater Collector
The steam generator is crucial for producing the superheated steam needed for sterilization.
It must be maintained at the correct water level to prevent damage or ineffective sterilization.
The wastewater collector handles the excess steam and hot water.
Sometimes cooling or condensing it before it is drained.
In summary, the autoclave is a highly effective tool for sterilization.
Utilizing the principles of moist heat and high pressure to ensure that all microbes are killed.
Thereby ensuring the safety and sterility of medical and laboratory equipment.
