What are Autoclaves and How Do They Work?
Introduction
Sterilization is a critical component of infection control, preventing infections and killing potentially harmful pathogens. Autoclaves help disinfect instruments that have been exposed to contaminants, typically when heat or detergents alone are not enough. In this article, we’ll explain what a medical autoclave is, how they work, and what you can and cannot sterilize in an autoclave.
What Are Autoclaves and How Do They Work?
What is an Autoclave?
An autoclave, also known as a steam sterilizer, is a sterilization device used to eliminate bacteria, viruses and fungi from surgical instruments, medical tools, and lab equipment. Autoclaves are essential in environments such as hospitals, clinics, dental offices, and labs to ensure that medical instruments are free from pathogens.
Additionally, autoclaves use high-pressure steam at temperatures typically ranging from 250°F to 273°F (121°C to 134°C) for specific amounts of time to thoroughly sterilize instruments.
How does an Autoclave Work?
Loading Phase: Contaminated instruments and other medical waste are placed inside the autoclave to ensure proper spacing for steam circulation.
Heating Phase: The autoclave door is tightly sealed, and the chamber is heated to generate high-pressure steam.
Sterilization Phase: The instruments are exposed to a high-temperature steam for a set period, usually 15 to 30 minutes, effectively eliminating bacteria, viruses and fungi.
Drying Phase: Once sterilization is complete, the instruments are cooled before they can be safely handled and stored.
