AUTOCLAVING<br />

What is an autoclave?<br />

Autoclaving is the process of steam<br />

disinfection wherein, the waste is exposed to<br />

steam at high pressure and temperature to<br />

decontaminate the infectious waste.<br />

Autoclaves are found in research, diagnostic<br />

and microbiology laboratories, health centers<br />

and other places that require high-level<br />

disinfection. An autoclave consists of a metal<br />

chamber sealed by a charging door and<br />

surrounded by a steam jacket.<br />
