    .

  •      •  One set of sliding rails is installed which allows furnace move from
            one side to the other side automatically at variable speeds using
            the control knob.

  •      •  Vacuum flanges and the digital vacuum gauge are installed  for
            immediate use.

  •      •  PC Control:  

    •          º  An MTS-02 control module is included for PC control on
                  this furnace.

    •          º  The new version of PC module is now compatible
                  with Lab View 05/08/2014

    •          º  A laptop PC can be ordered for $500 together with the
                  furnace. We recommend ordering a computer (laptop)
                  from us to avoid software installation problems as we will
                  perform installation and testing before shipping. For more
                  information please

Application Notes



Click here to learn the installation of a gas regulator


  •      •  Tube furnaces with quartz tubes are designed for using under
             vacuum and low pressure < 0.12
    MPa (absolute pressure).

  •      •  Attention: A two-stage pressure regulator must be installed
            on the gas cylinder to limit the pressure to below 3 PSI for
            safe operation.

           regulator
    .


  •      •  The flow rate for gasses should be limited to < 200 SCCM (or 200
             ml/min) for reducing thermal shocks to the tube

  •      •  Vacuum limit definition for all quartz tube furnaces: * Vacuum
            pressures may only be safely used up to 1000°C

  •      •  Click here to learn How to set up quartz/ ceramic tube and vacuum
            flange for MTI Tube furnace
    .

  •      •  Quartz tubes should be replaced after every 10th use to ensure
            the best performance.


  •      •  Samples should never be placed on the tube directly; please order
            crucibles and boats from
     here.

  •      •  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.
