    Specific Introduction:
        KJ-1400X-II is a CE-certified dual temperature zone high temperature tube furnace, each heating zone is 12" in length, with 30 sections of intelligent temperature adjustment using silicon carbide rods as heating elements, and the maximum working temperature can reach 1400°C. By adjusting the temperature control program of the two temperature zones, the temperature field in the furnace tube forms a temperature gradient. This series of tube furnaces can use CVD or PVD methods to grow nano materials and produce various films.
    Furnace structure
    • ·Double shell structure
    • ·Using high-purity alumina fiber as the furnace material, and the surface is coated with alumina coating (which can improve heating efficiency and extend service life)
    Basic parameters
    • Thermocouple: S-type thermocouple. Suggested heating rate: below 1400℃≤10℃/min; above 1400℃≤5℃/min
    • Temperature: 1300℃ (1400℃<30min) Power supply: AC380, 50Hz Maximum power: 10KW
    Furnace tube size
    • ·Material: high purity corundum tube
    • ·Diameter φ60
    • ·Optional flange bracket
    Heating zone
    • Heating zone length: 580mm (dual temperature zone: 290mm+290mm)
    Heating element
    • U type 1500 grade silicon carbide rod
    • 1. The standard installation on the flange is a Φ8 pagoda nozzle joint
    • 2. In order to obtain a better pumping rate, KF25 adapters can be used
    • 3. In order to better pass the gas into the furnace tube, a 1/4" stainless steel ferrule joint can be used
    Temperature Control System
    • ·Contains a temperature controller
    • ·PID automatic temperature control system
    • ·Intelligent 30-segment programmable control
    • ·Temperature control accuracy: ±1℃
    • · Two temperature zones are controlled by two independent temperature control systems
    • ·Default DB9 PC communication connection port
    • ·Passed MET certification
    • ·Computer temperature control software can be purchased to control the heating curve and export data
    • Furnace size: 1350 L x 470 W x 750 H mm
    • Furnace size: 290X180X160X2
    Net weight
    • 150Kg
    • One year warranty and lifetime technical support.
    • Special tips: 1. Consumable parts such as heating elements, quartz tubes, sample crucibles, etc. are not included.
    • 2. Damage caused by the use of corrosive and acid gases is not covered by the warranty
    Vacuum system
    • ·It can reach 50mTorr by mechanical pump
    • ·It can reach 10E-5 Torr through molecular pump
    • ·A cold vacuum trap can be purchased to avoid pollution caused by the vacuum pump
    Quality Certification
    • All electrical components (>24V) have passed UL/MET/CSA/CE certification. If the customer pays the certification fee, the company guarantees that a single device has passed the German TUV certification or CAS certification.
    Precautions for use
    • ·The air pressure in the furnace tube cannot be higher than 0.02MPa
    • Do not use graphite crucible in alumina tube
    • ·Because the internal pressure of the gas cylinder is relatively high, a pressure reducing valve must be installed on the gas cylinder when the gas is fed into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The range of our company's pressure reducing valve is 0.01MPa-0.1MPa. It will be more precise and safe to use
    • ·When the temperature of the furnace body is higher than 1500℃, the furnace tube must not be in a vacuum state. The air pressure in the furnace tube must be equal to the atmospheric pressure and be kept at normal pressure.
    • ·The gas flow into the furnace tube must be less than 200SCCM to avoid the impact of the cold atmosphere on the heated corundum tube. The long-term use temperature of the corundum tube is <1750℃
    • ·For the sample heating experiment, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you should always pay attention to the indication of the pressure gauge. If the indication of the air pressure is greater than 0.02MPa, you must open the vent valve immediately to prevent accidents (such as furnace tube rupture, flange flying, etc.)
