Identify one common method of sterilization used in laboratories.

Autoclaving is a widely recognized and effective method of sterilization used in laboratories. This process involves using high-pressure steam at a temperature of 121 degrees Celsius (250 degrees Fahrenheit) for a specific time, typically around 15-30 minutes, depending on the load. The combination of heat and pressure works to kill a broad spectrum of microorganisms, including bacteria, viruses, fungi, and spores that can withstand lower temperatures.

The significance of autoclaving lies in its ability to provide a reliable method for ensuring that any tools, equipment, and media used in lab environments are free from all forms of microbial life, thus maintaining a sterile working environment and preventing cross-contamination in experiments or clinical settings. This is crucial, especially in fields like microbiology, where contamination can lead to false results or compromised samples.
