Designed with sample protection as a priority
Your laboratory oven is an invaluable part of your daily workflow, enabling simple glassware drying to the most complex, controlled heating applications. Our heating and drying ovens portfolio ensures temperature stability and reproducibility for all your desired application needs. Helping to enable maximum efficiency, safety, and ease of use, Thermo Scientific Heratherm heating and drying ovens are designed with sample protection as a top priority.
Understanding Gravity and Mechanical convection
How Gravity Convection works
In a gravity convection oven, the temperature distribution is based on warm air moving upwards (see above). There is no fan that actively distributes the air inside the chamber. The benefit of this technology is very low air turbulences for gentle drying and heating.
How Mechanical Convection works
In a mechanical convection (or forced air) oven an integrated fan actively moves the air inside the chamber – resulting in an even temperature distribution throughout the chamber (see above). One benefit is optimal temperature uniformity for reproducible results, for example in material testing and for drying protocols with very tight temperature requirements. Another advantage is a much faster drying process compared to gravity convection. When opening the door, the temperature will recover faster to the set temperature level in a mechanical convection oven.
