Why do we autoclave at 121 degree Celsius?
Temperature. The standard temperature for an autoclave is 121 degrees Celsius. … The reason for this is that simply bringing something up to the temperature of boiling water, 100 degrees Celsius (212 degrees Fahrenheit), is not sufficient to sterilize it because bacterial spores can survive this temperature.
