Sterilization is the process of eliminating all forms of germs, including bacteria, viruses, fungi, and spores, from objects or surfaces. There are several ways to achieve sterilization:
-
Heat:
- Autoclaving: Using steam under pressure to kill microorganisms.
- Dry Heat: Using hot air to sterilize items, typically at high temperatures for a certain period.
-
Chemicals:
- Chemical Sterilants: Using strong chemicals like ethylene oxide or hydrogen peroxide to kill germs, often used for heat-sensitive equipment.
-
Radiation:
- Gamma Rays or X-rays: Using high-energy radiation to kill microorganisms, commonly used for medical supplies.
-
Filtration:
- Mechanical Filtration: Removing microorganisms from liquids or gases by passing them through filters with very small pores.
These methods ensure that tools, equipment, and surfaces are free from harmful germs, making them safe for medical procedures and other purposes.
