  • Two-Year Manufacturer Parts and Service Warranty

Gravity vs. Mechanical Convection
Gravity convection involves gentle drying and heating with low air turbulences ideal for working with materials that are sensitive to airflow such as powders and foils. These units are designed to protect delicate samples while offering temperature uniformity of ±°C with temperature stability of ±0.4°C at 150°C.

Mechanical convection is suitable for faster sample drying and heating with superior temperature uniformity of ±3.3°C with a temperature stability of ±0.3°C at 150°C.
