gravity convection

gravity convection

The transfer of heat resulting from differences in density of air or water (because of differences in temperature), that thereby causes the flow of air or water.

The gravity convection technology heats samples gently, without over-drying.
When using the gravity convection feature of a microbiological incubator, temperature distribution is based on warm air moving upward, although there is no fan to actively distribute air inside the chamber.
With a stainless steel interior, the General Protocol incubators use gravity convection to provide enhanced temperature uniformity, ranging from S C above ambient to 75 C.
The gravity convection option gives gentle drying and heating with low air turbulences, and is good for working with materials that are sensitive to airflow such as powders and foils?.
Air movement in a gravity convection oven occurs by its natural tendency to rise when heated.
The oven measures 12" x 10" x 10", and 800-W are installed in Incoloy-sheathed tubular elements to heat the unit, while gravity convection provides the airflow to the load.
Available with mechanical or gravity convection, the ovens meet all standard heating and drying needs.
Additional features include forced air or natural gravity convection, adjustable fresh air supply, and heating elements on all four chamber walls.
