Two Zone IR-Heating RTP Tube Furnace (4'' ID ) with Sliding Sample Holders - OTF-1200X-IR-IISL


Please email for lead time
Item Number: OTF1200XIRIISL
Transported by LTL Freight (Truck)
OTF-1200X-IR-IISL is a dual-zone IR heated rapid thermal processing (RTP) tube furnace with 4" ID quartz tube and two sliding sample holders for easy operation. It is capable of achieving a maximum heating rate of 50 °C/s  and a cooling rate of 117 °C/min. The furnace is designed for growing two-dimension and superconducting materials via hybrid physical-chemical vapor deposition (HPCVD), where one heating zone is used as a solid evaporating source and another zone is for vapor deposition. The precision temperature controllers are able to set up programmable heating and cooling profiles with up to 30 temperature segments.

Application Notes

Click here to learn the installation of a gas regulator

  • Tube furnaces with quartz tubes are designed for use 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. Click here to learn the installation of a gas 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 a 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 below.
