A sterilizer is a device used to eliminate all forms of bacteria, viruses, and other microorganisms from objects or surfaces. It is commonly used in medical settings, such as hospitals and clinics, to ensure that surgical instruments and equipment are free from harmful pathogens. Sterilizers can use various methods, including heat, steam, or chemical agents, to achieve this level of cleanliness. In addition to medical applications, sterilizers are also used in laboratories, food processing, and even in homes for baby bottles and kitchen utensils. The effectiveness of a sterilizer is crucial for preventing infections and maintaining hygiene in environments where cleanliness is essential, such as in the presence of patients or food.
