    Specific Introduction:
        KJ-1200X-PGEP is a versatile ultrasonic spray furnace system designed for the synthesis of core-shell nanoparticles. Three major subsystems (ultrasonic enhanced aerosol generator, tube furnace, and electrostatic precipitator) are employed on three processes including aerosol generation, thermal decomposition, and nanoparticle collection. Such a system enables advanced synthetic method that provides control over particle size, morphology, and nano/microstructure.
    System Features
    • Aerosol Generation: 2.4MHz Ultrasonic Enhanced Bubbler can "evaporate" target solution with literally no heat generated. An elongated Tee tube wrapped by a heating tape that connects inline with an ultrasonic bubbler can prevent condensing liquid from streaming into the tube furnace and promote the generation of aerosol. 
    • Thermal Decomposition: Tube Furnace can be heated up to 1200C maximum. Bypassing the aerosol flux across the temperature and flow rate regulated firing zone, chemical and physical processes may proceed.  
    • Nanopowder Collection: an electrostatic precipitator (1.2 L, up to 30 kV) can effectively collect nanoparticles from the carrier gas flow

    Application Notes

    • A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
    • Never heat the furnace while the gas valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating.
    • Wrapping Aluminum foil to achieve better thermal conductivity.
