Hot Air Oven a laboratory instrument which is used for various applications in several industries. Hot air oven device is driven by advanced technology which is mainly used to sterilize the product with dry heat. Professionally Triple walled construction helps this device complete its task silently.
Dry heat is suitable for sterilizing metal instruments that rust or dull in the presence of the water vapour. With the help of a thermostat it controls the temperature of the inner chamber for the required time. Air circulating fans help to provide uniform distribution of heat.
The major reason hot air ovens are getting popular is because hot air ovens do not require the water or pressure to be built up in the oven, that is why the chemical industry, pharmaceutical and hospital use to sterilize the product in hot air ovens.

Natural Convection Hot Air Oven refers to a Laboratory Instrument that uses dry heat for equipment like Glassware and other materials.
Its primary function is to eliminate moisture from the material. Accordingly, it is predominantly employed in applications like annealing, baking, curing, drying, and such likes. Aside from these, it is also used for the measurement of mixed liquor suspended solids (MLSS), and even storage of some products at constant temperature in hospitals and laboratories, etc.
Used for various applications in several industries, a Hot Air Oven device is primarily driven by advanced technology; and is predominantly used for sterilizing a product with dry heat also for drying for Glassware.
The prominence of dry heat is it helps to sterilize metal instruments that either rust or dull in the presence of water vapor. With assistance from a thermostat, it controls the temperature of the inner chambers for a specific period of time. Likewise, air circulating fans in a hot air oven facilitates uniform distribution of heat.
HOT AIR OVEN SPECIFICATIONS AND FEATURES
Triple-walled in construction with an inner made of stainless steel -304 Grade and Exterior of CRCA steel with powder-coat finish, a Hot Air Oven specifications includes
- Temperature Range: 5°C above ambient to 250°C up to 300°C. (on request)
- Temperature Accuracy: ± 1°C or better.

HOT AIR OVEN PRINCIPLE
A Hot Air Oven principle revolves around utilization of convection, conduction, and radiation, as per the dry air sterilization procedure.
- Heating components heat the oven’s chamber air. This can be evenly circulated with the use of fans thereby exposing sample surfaces to hot, dry air.
- Exposure of sample surfaces to hot, dry air causes the external surface of an object to heat-up. Simultaneously, the conduction mechanism transfers’ the heat to the object’s core.
- Transfer of heat causes microorganisms’ internal water to evaporate. This results in oxidative damage to cellular components; denaturation of proteins; toxic consequence of high electrolyte levels; and finally, death.
Hot Air Oven sterilization involves the evaluation of the efficacy of any kind of instrument with quality testing.
- Biological indicators are used for testing the hot air oven’s functionality.
- Clostridium Tetani Spores from a non-toxic-genic strain are employed as the microbiological test for quality control.
- 106 spor-impregnated paper-strips are placed in envelopes and inserted into proper packaging.
In case, there is effective and proper hot air oven sterilization, the spores will be eliminated and later there will be no further growth.
HOT AIR OVEN USES
Also called as Forced Air Circulating Ovens, Hot Air Oven uses relate to
- Hot Air Oven Sterilization of
- Sterilize Powder like starch, sulfadiazine, and zinc oxide.
- Materials that contain oils.
- Material Equipment like blades, scalpels, and scissors.
- N95 Masks,
- Tools and Packaging Materials.
Hot Air Oven uses are predominantly in Microbiology Laboratories, Life Sciences, MLSS Analysis, and several applications based on research. Aside from these, there are industries that employ hot air circulation ovens like chemical and pharmaceutical electronic components, steel manufacture, food and beverage, and textile, etc.
Labindia Instruments is a prominent Hot Air Oven Manufacturer known for its high-class hot air ovens at the best hot air oven price in India.
When sterilizing materials, it is important to follow the hot air oven manufacturer’s instructions. That’s because there are some materials that are sensitive to high temperatures or known to release harmful fumes when heated. Additionally before handling them after they have been sterilized, it is also important to allow the materials to cool down.
