What is a hot air oven?

A hot air oven is a piece of electronic device used to sterilize objects. It often occurs in hospitals where doctors use it to sterilize surgical equipment. Scientists and laboratory technicians also often use this because the oven in hot air does not experience the same accumulation of internal pressure as other sterilization devices as an autoclave.

The interior of the hot air furnace contains a digital thermostat that controls a temperature that usually ranges anywhere from 122 ° F (50 ° C) to 572 ° C (300 ° C). The oven itself is made of double construction, which is designed to hold heat and reduce energy performance. The exterior of the unit is composed of metal and the interior is made of poor conductor. Meanwhile, the space filled with air, which provides further insulation. Inside the unit, the heat is distributed evenly by means of a built -in fan.

Compared to other types of sterilization devices, the furnaces on the hot air are Fairly Compact.Dry heat formed by a furnace may not be as beneficial in killing harmful organisms as the furnaces producing are moist. However, temperatures in the oven in hot air are usually comparable to temperatures found in other sterilization units. In addition, the hot air cycle is usually much shorter compared to steam sterilization units.

Before they can be operated properly, the preheating of the mainland must be

hot air. Preheating time is necessary for effective complete sterilization cycle. The opening of the chamber door before the heating is completed allows you to heat and requires the unit to be completely turned off and the preheating process begins again.

Conventional hot air sterilization oven takes place at a typical cycle at 320 ° F (160 ° C). At this temperature, it takes approximately 90 minutes for the unit to complete its cycle. There are also a convection hot airperts that useThey are forced air at 374 ° F (190 ° C) to shorten the cycle time. The device wrapped in the thermally safe material can be sterilized in a convection furnace in about 12 minutes. Sterilization items last only about 6 minutes.

due to high temperatures inside hot air furnaces can only be used with certain materials. Powders and glass are usually able to withstand extreme heat, as well as pieces of surgical equipment that would rust in wet air. However, other types of laboratory and medical facilities, including metal houses, rubber or plastic and laundry objects, may be destroyed inside the hot air oven.
