Flask Sterilization

[Roberta]

I will leave it to members who do flasking to advise on what might work for you. But as far as temperature is concerned, the maximum temperature that can be achieved with boiling water at atmospheric pressure is 100 deg C at sea level, lower at elevations above that. To get higher temperatures you have to be able to raise the pressure (which is where the pressure cooker comes in). You can't get around the laws of physics and chemistry...
