• A hot air oven is used to heat up the products at a uniform temperature. A hot air oven is used to sterilize the product in a particular period of time under specific conditions like humidity, pressure, and other environmental factors. Hot air oven controls the humidity level by removing moisture from the products and combining the airflow with heat.

Objective

• Hot air ovens are laboratory and scientific equipment which uses dry heat (hot air mixture) for sterilization of laboratory equipment. The dry heat sterilization process is developed by Louis Pasteur to sterilize the equipment using the hot air ovens.

Operating Mechanism

• Hot air oven is a type of dry heat sterilization. Dry heat sterilization is used on equipment that cannot be wet and on material that will not melt, catch fire, or change form when exposed to high temperatures. Moist heat sterilization uses water to boil items or steam them to sterilize and doesn't take as long as dry heat sterilization. Examples of items that aren't sterilized in a hot air oven are surgical dressings, rubber items, or plastic material.
