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

SPECIFICATIONS:

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 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 are included
  • Please click picture on the right to see principal of the furnace

  • 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 (please choose connector at picture below before order)
  • Optional.  You may order a  Compact  Liquid Vaporization Systems for better CVD ( Click picture below right )

Warning

Click here to learn the installation of a gas regulator
  • 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. Click here to learn the installation of a gas regulator.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
  • 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 H2/CH4 leaking detector installed.
Application Note
  • After CVD, the graphene must be transferred from the metal catalyst to another substrate for most applications. By using the graphene transfer tape, the residue can be low.
