Labotemp Controlled Atmosphere Furnace FMU-15 is a compact high-temperature laboratory muffle furnace designed for precise thermal processing up to 1200 °C. It features a box furnace design with three-sided resistance heating and PID-controlled temperature regulation, delivering stable and repeatable results with ±1 °C accuracy. The vacuum sealed chamber and integrated inert gas system allow safe introduction of nitrogen, argon, oxygen, and other non-reactive gases, making it suitable for controlled atmosphere experiments. With high purity ceramic fiber insulation and a robust steel outer shell, the furnace ensures low heat loss, energy efficiency, and long term operational stability for daily laboratory use.
FMU-15 is widely used in laboratory research and material testing applications such as ceramic and powder sintering, calcination, annealing, carbon material treatment, and lithium battery material research. Designed for universities, research institutes, and industrial laboratories, this controlled atmosphere muffle furnace offers a reliable solution where precision, safety, and atmosphere control are essential.
