An autoclave is a specialized device used to sterilize equipment and materials by using high-pressure steam. It operates at elevated temperatures, typically around 121 degrees Celsius (250 degrees Fahrenheit), which effectively kills bacteria, viruses, and other pathogens. Autoclaves are commonly used in medical facilities, 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 the most resistant microorganisms are eliminated. Autoclaves are essential for maintaining hygiene and safety in settings such as hospitals, where instruments must be free from contamination.
