INTSUPERMAI Muffle Furnace Lab 1700℃ Vacuum Atmosphere Furnace, ±1℃ PID Control, Vacuum/N₂/Ar/H₂ Gas System, 20℃/min Heating, MoSi₂ Heater, Ceramic Sintering, Metallurgy, Ash Testing 110V, 4000W

The Intelligent High-Temperature Vacuum Atmosphere Muffle Furnace features smart temperature control, multi-atmosphere compatibility, and high-efficiency safety. The furnace employs pre-vacuum pumping to minimize oxygen content, followed by inert gas (N2/Ar) infusion, creating an ideal controlled-atmosphere thermal environment. With temperature control accuracy of ±1℃, rapid heating (≤20℃/min), and energy-saving design, its high-purity alumina fiber chamber enables applications in material science (ceramic sintering, metallurgy), chemical synthesis, and ash testing. Widely adopted in research institutes, university labs, and small-batch industrial precision processing.
