Laboratory Hot Air Oven – Different Types and Applications

Laboratory Hot Air Oven – Different Types and Applications

Laboratory hot air oven is concise heating equipment that finds many applications in the industrial research and development sector. These are also used in laboratories where the thermal convection provided by the tool is necessary. The ovens are specifically used to bring effects such as sterilizing, drying, baking, annealing etc on the particular compound. These vary greatly in terms of size, temperature, heat source and many others. Lab oven is referred as a thermal processing unit that operates lower temperature ranging below 400 degrees. The ovens are also popularly used in industrial settings to perform melting, aging, curing, soldering, hot pressing and sintering of products. 

Varied Types of Hot Air Ovens

The varied types of these ovens are identified and classified according to different specifications. This includes temperature range, internal volume, pressure range etc. The lab kilns or ovens come in a wide variety of types such as muffle, cabinet, walk-in, vacuum, vertical and so on.


Cabinet ovens are equipments that are used to process smaller quantities in one batch and are set up on integral stand. The muffle ovens make use of indirect heating where the target product or material is contained in external refractory vessel. Walk in configuration ovens consist double doors along with internal shelves and used for extensive or huge requirement. A laboratory vacuum oven is the type where the heating and processing is conducted under vacuum to eliminate contamination.

They Are Also Available in Different Styles

Apart from classification in configuration the laboratory furnaces also come in variety of styles that include ovens with horizontal airflow, forced convection and pass through machines. Each type of oven is made suitable for specific range of applications in laboratory, medical clinic or industrial setting. The most commonly used are benchtop and cabinet ovens that are compatible for wide range of requirements in different sectors.


These lab furnaces can be controlled with a set point system, but certain advanced models also come with a feature of programmable controls. A reputed hot air oven manufacturer also offers other set of features that include alarms, cooling systems, air purification system, shelves and cabinets, sample holders, logging system and so on.


These working units offer different heat sources or thermal transfer such as induction, microwave, radio, electric, dielectric, propane, natural gas etc. These also come in great variety according to size requirements for example vertical ovens that offer a space saving option to small laboratories. The type should be selected according to your melting and drying requirements.


A hot air oven instrument is used in a wide range of applications, including food industry, pharmaceutical industry, college laboratory, hospitals, textile industry, bandages making, baking, microbiology and chemical laboratory.


Yatherm Hot air ovens can be used for the operation that requires the temperature of 300°C and readability 0.00°C.
