    KJ-1200X-II-UL is a CE Certified and ready to pass UL/CSA certification (details please refer to the specification below) furnace with optional quartz Tube (60, 80, 100mm) & Vacuum Flanges.

    Specific Introduction:
        KJ-1200X-II-UL is a CE Certified and ready to pass UL/CSA certification (details please refer to the specification below) furnace with optional quartz Tube (60, 80, 100mm) & Vacuum Flanges. Split two-zone tube furnace which can achieve faster heating up to 1200oC and create a different thermal gradient by setting the different temperatures of each zone. The furnace includes one 40" L fused quartz tube with vacuum flanges and valves for immediate use. Two 30 segments of programmable temperature controllers are installed. The microprocessor-based self-tuning PID controller provides excellent control without overshooting the set temperature. It is a perfect tool for CVD applications such as preparing nanomaterials and film.

    Furnace structure
    • Double-layer steel case with two cooling fans, which ensure low surface temperature
    • Energy-saving high purity fibrous alumina liner and  insulation
    • High purity Al2O3 coating  which provides a longer service life
    Power 3 KW (20A Breaker)
    Voltage AC 208-240V Single Phase, 50/60 Hz, a power cord is included without the plug.
    Temperature range 100~1100° C (Continuous); 1200° C (<1 hour) 
    Max. Heating Rate ≤ 20° C /min
    Tube Accessories (When the tube size is selected, compatible accessories will match it automatically, please refer to standard package for details)
    • One fused quartz tube with 1000mm L is included 
    • Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
    • Quartz block (Optional) is ideal for more cleanness and higher achievable vacuum, available at extra cost
    • You may order flange support to avoid tube rotating

    Heating Zone Length
    • Two zones: each zone length 8" (200 mm)
    • Total 16" (400 mm) heating zone

    Constant Temp. Zone
    • 150mm (+/-1°C) for each heating zone
    • A longer constant temperature zone ( about 250mm ) can be created by setting both zones at the same temperature 
    Temperature Controllers
    • 2 MET certified digital controllers with 30 programmable segments for precise control of heating rate, cooling rate and dwell time
    • Built-in PID Auto-Tune function with overheating & broken thermocouple protection
    • Over-temperature protection and alarm allows for operation without attendant(s)
    • +/- 1 ºC temperature accuracy
    • Two K-type thermocouples (one for each zone)
    • RS485 Communications Port
    • Optional:
      • The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at an extra cost
      • If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer laptop from us 
    Thermal Couples
    • K type
    Temperature Accuracy +/- 1° C
    Heating Element Fe-Cr-Al Alloy doped by Mo
    Vacuum Flange & Fitting Ports
    (Certain flange size will be matched as the tube size is selected in options bar)
    • One pair of SS 304 vacuum flange with double high-temperature silicone O-rings are Included
    • One Vacuum pressure gauge is installed, one digital vacuum gauge is available upon request at an extra cost
    • The flange set has two 1/4'' Bard fittings, two-needle valve, one set of KF25 quick clamp, one blank flange fitting, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert) and a KF25 vacuum port
    • The vacuum level can reach 10^-2 torr by a quality mechanical vacuum pump and 10^-5 torr by a molecular pump
    • Optional: Please choose quality mechanical pump or molecular pump
    • Optional (only for 80mm O.D and 100mm O.D tube size): Hinged type flanges with support frame for easy sample loading/unloading is available at an extra cost.
    • Hinged Vacuum Sealing Assembly with Flange Support for 80 mm Dia Tube Furnace - EQ-FL-80KF25-HG
    • Hinged Vacuum Sealing Assembly with Flange Support for 100 mm Dia Tube Furnace - EQ-FL-101KF25-HG
    • You may order a pressure control module to keep the chamber at a constant pressure
    • You may order gas flow control system to keep constant mixing gas flow

    Application Notes

    • Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.Vacuum pressure may only be safely used up to 1000°C. The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube.
    • Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation.
    • You can set up the different temperature with each zone to create a thermal gradient for CVD deposition
