Microorganisms and bacterial spores are destroyed in part heating oven using extremely high temperatures maintained for several hours. By heating the item's exterior surfaces, which the oven then absorbs and transport towards the items center, conduction sterilizes the object. It is a piece of scientific equipment that employs dry heat to sterilize supplies and other things. Part heating oven frequently employs temperatures and times of 170 degrees Celsius for 30 minutes, 160 degrees Celsius for 60 minutes, and 150 degrees Celsius for 150 minutes to sterilize goods. It performs sterilization via dry heat conduction. The material absorbs heat as it moves from the outside layer to the center, reaching sterilizing temperature as a whole.
