Hot Air Oven

Product Details:

Hot air ovens are electrical devices which use dry heat to sterilize. They were originally developed by Pasteur.^[1] Generally, they use a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy, the inner layer being a poor conductor and outer layer being metallic. There is also an air filled space in between to aid insulation. An air circulating fan helps in uniform distribution of the heat. These are fitted with the adjustable wire mesh plated trays or aluminium trays and may have an on/off rocker switch, as well as indicators and controls for temperature and holding time. The capacities of these ovens vary. Power supply needs vary from country to country, depending on the voltage and frequency (hertz) used. Temperature sensitive tapes or biological indicators using bacterial spores can be used as controls, to test for the efficacy of the device during use.

A hot air oven is used to sterilize equipment and materials used in the medical field. This lesson will discuss what a hot air oven is and how it works.What Is a Hot Air Oven?

Gina is a new employee at South Hospital. She's working in the sterilization department, which she has little experience in. Gina's manager is orienting her to the process of dry heat sterilization using the hot air oven. She begins by reviewing what it is and why it's used.

A 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.

Items that are sterilized in a hot air oven include:

• Glassware (like petri dishes, flasks, pipettes, and test tubes)
• Powders (like starch, zinc oxide, and sulfadiazine)
• Materials that contain oils
• Metal equipment (like scalpels, scissors, and blades)

Hot air ovens use extremely high temperatures over several hours to destroy microorganisms and bacterial spores. The ovens use conduction to sterilize items by heating the outside surfaces of the item, which then absorbs the heat and moves it towards the center of the item.

The commonly-used temperatures and time that hot air ovens need to sterilize materials is 170 degrees Celsius for 30 minutes, 160 degrees Celsius for 60 minutes, and 150 degrees Celsius for 150 minutes.

Gina understands that hot air ovens sterilize equipment over long periods of time, so she has to be organized in determining what items will be sterilized at what time. This depends on when the equipment needs to be available again. Gina's manager now explains the different types of hot air ovens.
