A gravity convection oven is a laboratory heating and drying oven that uses natural air circulation instead of a fan or blower. Bionics Scientific manufactures gravity convection ovens for applications involving lightweight materials such as powders, fabrics, films and granular substances that may be disturbed by forced airflow.
Unlike mechanical convection ovens, gravity convection models operate without a circulation fan inside the chamber. This makes them suitable for laboratory processes where gentle heating and reduced air turbulence are important. They can also be considered for applications involving multiple samples, subject to the sample properties and operating procedure.
Bionics Scientific offers different gravity oven models to meet laboratory capacity and application requirements. Available options include economical and premium configurations, with choices of chamber and exterior materials and temperature control systems. Contact our team to discuss the appropriate model for your application.

A gravity convection oven is a laboratory oven that uses natural air circulation without a fan or blower.
It heats air naturally. Hot air rises while cooler air moves down, creating natural circulation inside the chamber.
No. It uses natural convection instead of a mechanical fan or blower.
It is suitable for drying powders, fabrics, films and lightweight granular materials.
Bionics Scientific offers models with chamber capacities from 30 to 336 litres.
The specified temperature range is ambient +5°C to 250°C.
The specified temperature accuracy is ±2°C, with temperature uniformity of ±1°C.
A gravity convection oven uses natural air circulation, while a mechanical convection oven uses a fan or blower.
