STF Series Tube Furnaces
The LABTHERM STF Series tube furnaces are designed for laboratory heat treatment processes, operable both horizontally and vertically. These furnaces reach temperatures up to 1300°C and offer flexibility in zone configurations, making them ideal for controlled atmospheric conditions.
The STF Series features wire heating elements located around the hot-zone, ensuring excellent temperature uniformity. The furnace allows easy tube/reactor replacement and accommodates various tube diameters for diverse applications.
Built with dual-skin housing for stability, these furnaces feature a phosphate-coated steel body and an optimized element surface load for durability and extended life.
