What is one common method for sterilizing laboratory equipment?

Autoclaving is a widely recognized and effective method for sterilizing laboratory equipment. This process involves using high-pressure steam at temperatures typically around 121 degrees Celsius for a specified period, usually 15 to 30 minutes, depending on the material being sterilized. The autoclave provides a controlled environment that effectively eliminates all forms of microbial life, including bacteria, viruses, and spores, making it highly reliable for ensuring that tools and materials used in laboratory settings are free from contamination.

Other methods mentioned may not achieve the same level of sterilization. For instance, boiling water might kill most bacteria but is less effective against certain resilient spores and does not guarantee complete sterility. Wiping with alcohol wipes can disinfect surfaces but may not sterilize items, particularly those that are porous or in complex forms, and may not be effective against all microorganisms. Using a microwave is not a standard method for sterilization, as it can heat unevenly and does not consistently reach the temperatures required for effective sterilization.
