A steam sterilizer is a device used to eliminate bacteria, viruses, and other pathogens from medical instruments and laboratory equipment. It operates by using high-pressure steam to achieve temperatures that effectively kill microorganisms. This process is essential in maintaining hygiene and safety in healthcare settings. Typically, steam sterilizers come in various sizes, from small tabletop models to large industrial units. They are commonly used in hospitals, dental offices, and research laboratories. The effectiveness of a steam sterilizer depends on factors such as temperature, pressure, and exposure time, ensuring that items are thoroughly sterilized before use.
