Two Zone IR Heated RTP Tube Furnace (4'' ID ) with Slide-able Sample Holder under Vacuum -OTF-1200X-IR-IISL


Please email for lead time
Item Number: OTF-1200X-IR-IISL
Transported by LTL Freight (Truck)
OTF-1200X-IR-IISL is dual zone IR heated RTP tube furnace with  4" ID quartz tube and slidable sample holder which is inside retractable bellows vacuum bellows.  It is capable of achieving a max. heating rate > 50°C/s  and a cooling rate  > 10°C/s. The furnace is designed for growing two dimension materials via HPCVD, where one heating zone is used as solid evaporating source and another zone for sample deposition.

Vacuum Flanges

  • Stainless steel quick vacuum flanges are installed on both ends of the tube for easy assembling
  • 1/4"diameter  feedthrough on left flange  for inserting  K-type thermal couple
  • Digital vacuum gauge is included
  • KF25 right angle valve is installed for connecting to a vacuum pump
  • Needle valve for vacuum release is included
  • One  retractable bellows is installed on left flange, which allows sample hold sliding to cold under controlled vacuum or atmosphere

Vacuum Level 

  •  Limited by vacuum pump
    • 10^-2 torr can be achieved by mechanical pump
    • 10^-4 torr can be reached by molecular pump
  • The pump is not included . ( please clic picture below to order )
  •    

Water Cooling  (optional)

  • Cooling water is required.
  • Please make sure the flow rate of cooling water is ≥ 10L/min, water temp. < 25ºC; pressure > 25 PSI.
  • We suggest using the EQ-KJ5000 Series recirculating water chiller as a cooling system (please order separately at related products below) to save water.   
  • Warning: This RTP furnace's max dwelling time shall be less than 600 seconds at 1000ºC ~ 1100ºC with tap water, otherwise, O-ring may melt.

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. 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 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.
