The heat that an autoclave delivers via pressurized steam kills bacteria and other microorganisms by causing the organisms' structural proteins and enzymes to lose their shape in an irreversible way, denaturing and coagulating them and making them nonfunctional.

What does an autoclave destroy?

Autoclaves are designed especially to kill germs, bacteria, and spores. It is a power sterilisation device because it utilises steam to kill all different kinds of microbes at a set level of pressure and temperature.

Does an autoclave kill all bacteria?

Autoclaves and Dry Heat Sterilizers​

Autoclaves sterilize tools by using high levels of heat and pressure. They kill all forms of microbial life, such as bacteria, viruses, and even spores. Typically, autoclaves run at a temperature of 270 degrees Fahrenheit for thirty (30) minutes.
