An autoclave is a specialized device used to sterilize equipment and materials by using high-pressure steam. It operates at temperatures above 100 degrees Celsius, effectively killing bacteria, viruses, and spores. Autoclaves are commonly used in medical settings, laboratories, and industries that require sterile conditions. The process involves placing items inside the autoclave chamber, sealing it, and then heating the steam under pressure. This method ensures that even hard-to-reach areas of instruments are sterilized. Autoclaves are essential for maintaining hygiene and safety in environments such as hospitals, where tools like surgical instruments must be free of contaminants.
