Question

Why moist heat sterilization is more effective than dry heat sterilization?

Answer 1

Hello... Here is your answer

Moist Heat Sterilization

Water at high pressure level is used in moist heat sterilization. Autoclave is the instrument in which this process is carried out. The temperature of the steam in this method is lower when compared with dry heat sterilization, but the high pressure helps with effective sterilization to take place.

Dry Heat Sterilization

In dry heat sterilization, dry heat is used for sterilizing different materials. Heated air or fire is used in this process. As compared to the moist heat sterilization, the temperature in this method is higher. The temperature is usually higher than 356° F or 180 °C.

Dry heat helps kill the organisms using the destructive oxidation method.
