Definition

An autoclave is a device that uses steam under high pressure to sterilize equipment and materials. It is commonly used in microbiology labs to eliminate all forms of microbial life, including spores.

5 Must Know Facts For Your Next Test

1. Autoclaves typically operate at 121°C and 15 psi for a minimum of 15 minutes.
2. Sterilization via autoclaving is effective against bacteria, viruses, fungi, and spores.
3. Indicators such as autoclave tape are used to confirm successful sterilization cycles.
4. Items that cannot withstand high heat or moisture should not be autoclaved.
5. Regular maintenance and validation of autoclaves are essential to ensure their effectiveness.
