Principle Of Hot Air Oven Method

Sterilization by dry heat is accomplished by conduction.

Principle of hot air oven method. The heat is absorbed by the outside surface of the item then passes towards the centre of the item layer by layer. The static air hot air oven works by using a heating coil at the bottom of the oven. For the item to be fully sterilized it needs to reach the required temperature. They were originally developed by pasteur.

Hot air oven is the most common method of sterilization in the laboratory working on dry heat. Hot air ovens are electrical devices which use dry heat to sterilize. Principle of hot air oven. The heat rises throughout the oven and takes a longer time to reach the desired temperature.

The entire item will eventually reach the temperature required for the sterilization to take place. The principle of hot air oven dry heat sterilization sterilization is achieved by means of conduction. The entire item will eventually reach the temperature required for sterilization to take place. It is a physical method of sterilization due to dry heat.

Their double walled insulation keeps the heat in and conserves energy the inner layer being a poor conductor and outer layer being metallic. Sterilization is the process of removing or destroying all microorganisms including viruses bacteria and their spores from the article or surface without destroying its quality and quantity. The machine is equipped with various components to ensure the uniform heating throughout the chamber. Working principle of hot air oven sterilizing by dry heat is accomplished by conduction.

The working principle is based on fine gravity air convection in an electrically heated chamber.
