The metallic HTK series from Carbolite includes high-temperature furnaces with heaters made of tungsten (HTK W) or molybdenum (HTK MO) and reach up to 2200 °C. Available in four sizes (8-120 l), they are suitable for laboratories, pilot plants and production. The front door facilitates loading and unloading. The metal construction ensures high purity of the inert gas atmosphere and vacuum. A high vacuum upgrade is available as an option. Frequently used gases are nitrogen, argon and hydrogen. A retort can be used for gas flow and temperature uniformity.

The AAF ashing ovens are designed for the complete ashing of samples at up to 1100 °C. With a programmable controller, efficient air flow (4-5 air changes/minute) and heating elements on four sides, they offer optimum temperature distribution. They comply with ISO 1171:2010, ASTM D3174-04 and ASTM D4422 - ideal for food, plastics, coal, etc. The robust ceramic muffle reliably protects the heating elements.

The HTF chamber furnace range from Carbolite offers precise heat treatment up to 1800 °C for applications such as sintering, annealing and calcination. It offers uniform temperature distribution, high energy efficiency and user-friendly control - ideal for research, quality control and production in areas such as ceramics, metallurgy and materials science.
