A laboratory hot air oven uses forced air circulation to provide controlled heating for drying, baking, ageing and other laboratory applications. A blower circulates heated air throughout the chamber to help maintain uniform temperature around the samples.
Bionics Scientific manufactures hot air ovens with temperature control up to 250°C for laboratory, pharmaceutical, textile, research and testing applications. Models are available in different chamber capacities, with PID temperature control and optional configurations according to application requirements. Explore our laboratory oven range for other controlled-heating equipment.
The hot air oven works on the principle of forced air convection. Heating elements generate heat while a motor driven fan circulates hot air uniformly throughout the chamber. A PT-100 sensor continuously measures temperature and the PID controller regulates heating to maintain the selected temperature accurately.

Laboratory hot air ovens are used for controlled heating, drying, baking and thermal testing of suitable materials. Common applications include:
For information about dry-heat sterilization methods, refer to the CDC guidance on sterilization methods .
Laboratory hot air ovens are designed for controlled heating from ambient temperature up to 250°C, depending on the selected model and configuration. A PID temperature controller works with a PT-100 sensor to monitor and regulate chamber temperature during operation.
For more uniform heat distribution, a motor-driven circulation fan moves heated air throughout the chamber. The double-walled construction helps reduce heat loss and supports stable operating conditions.
The inner chamber is manufactured from stainless steel, while the outer body is designed for durable laboratory use. Removable and adjustable shelves are provided for arranging samples and laboratory materials inside the chamber.
Electric heating elements provide the required heat, while ventilation openings support controlled air exchange inside the chamber. Over-temperature and electrical protection features are provided according to the selected configuration.
