Two tube furnaces allow for reactions in argon, nitrogen, ammonia, hydrogen/nitrogen, carbon dioxide atmospheres. A tri-zone tube furnace allows for different zones of the tube to be heated to different temperatures at different heating rates, with temperature range of ambient-1200 °C. A second tube furnace utilizes one heating zone with temperature range of ambient-1600 °C. Quartz tubes can be used for ambient-1050 °C working temperatures, and alumina tubes for higher temperatures.
Model name: Carbolite EZS (tri-zone tube furnace), Carbolite CTF (tube furnace).
