  • High temperature vertical tube reactor


    Continuous Temp:

    Chamber/Tube size:


    ★ Upright furnace tube: The furnace body and furnace tube are vertical, and the fluidized bed design allows the reaction material to pass through the reaction zone smoothly.
    ★ Safety and anti-scalding: The furnace body adopts a double-layer structure, the surface temperature of the shell is low, and safety accidents such as scalding are not easy to occur.
    ★ Energy-saving furnace: The furnace is made of high-purity polycrystalline alumina ceramic fiber material, with high reflectivity, environmental protection and energy saving, balanced temperature field, and flexible temperature control.
    ★ Precise temperature control: Use S-type thermocouple and AL artificial intelligence regulator 518P temperature controller to automatically control temperature, with high temperature control accuracy.
    ★ Vacuum atmosphere: This furnace type can be evacuated (mechanical pump or vacuum unit can be selected according to the needs of vacuum degree), and can be filled with various reaction atmospheres (micro-positive pressure).
    ★ Scope of application: Mainly used in college laboratories, industrial and mining enterprise laboratories, high, medium and low temperature CVD processes, such as organic matter pyrolysis (or cracking), development of carbon nanotubes, crystalline silicon substrate coating, metal material diffusion Welding and heat treatment in vacuum or atmosphere, etc.

    Precautions The pressure in the furnace tube should not be higher than the normal atmospheric pressure 0.02MPa
    When gas is introduced into the furnace tube, a pressure reducing valve should be installed on the gas cylinder, and the range of the pressure reducing valve should be established as
    0.01MPa-0.1MPa, it will be more accurate and safe to use
    For the sample heating experiment, it is not recommended to close the exhaust valve and the intake valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you need to pay attention to the reading of the pressure gauge. If the pressure reading is greater than 0.02MPa, you must open the gas relief valve immediately to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
    When the temperature is higher than 900℃, the furnace tube cannot be in a vacuum state, and the air pressure in the furnace tube must be equal to the atmospheric pressure and kept at normal pressure
