Specific Introduction:
KJ-1200X-5-III-D4 is a dual tube and three-zone tube furnace with max. the working temperature of 1200°C for growing thin films on metallic foil by CVD, specially designed to make graphene and the flexible electrode for solar or battery electrode.

Parameters:

Features		Dual quartz tube: 130 mm Dia (5"). outside tube suspended by 101 mm Dia (4") tube inside. The metallic foil will be wrapped inside tube surface for CVD reaction Vacuum sealing flanges for the dual tube, which allow reactive gas to go through between two tubes ( 20mm space ) for reaction, and forced air can go through the central tube for fast cooling. Max. Working Temperature: 1200°C Valve and vacuum gauge is included
Furnace structure		Three heating zones: (900mm, 36" in total) Zone 1: 300mm (11.8") Zone 2: 300mm (11.8") Zone 3: 300 mm (11.8") Max. 25" (625 mm) long with ±1°C accuracy if set three zones at the same temperature. Three precision temperature controllers with 30 segment programmable and ±1° C accuracy. Max. Working Temperature: 1200°C Continuous Working Temperature: 1100°C Heating Rate: ≤ 20°C /min Constant Temperature Zone: 25" (625 mm) length (Three zones are heating at equal temperature simultaneously)
Processing Tubes		Two High purity Fused Quartz Tubes included Outside tube: 130mm O.D. x 122 mm I.D. x 1480 mm Inside tube: 102mm O.D. x 94 mm I.D. x 1800 mm
Vacuum sealed flanges		One pair of flange made of SS304, which seals tightly between tubes by two high-temperature O-rings (10-2 by the mechanical pump and 10-5 by the molecular pump ). The flange is built with water cooling jacket. When working temperature over 900°C, it is required to use cooling water. You may either use tap water or use our chilling water circulation at picture below One KF25 adapter is installed on the left flange to connect a vacuum pump. One stainless steel needle valve is installed on right flange Optional. You may order a Compact Liquid Vaporization Systems for better CVD
Optional		Copper Foil for Graphene Growth (150m length x 150mm width x 25um thickness)
Updated idea		You may put the furnace on a 1200 mm length mobile cart you may order our gas mixing module to support the furnace and deliver multi-gas to the dual tube furnace
Warning		All quartz tube furnaces are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 Mpa Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. The flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube For the use of flammable gasses such as H2 and CH4, please consult with MTI technical team for safety measures. We Strongly suggest that the furnace needs to be operated inside a fume hood with an H2/CH4 leaking detector installed.
