Item Number: OTF-1200X-RTP-4-SL
Transported by LTL Freight (Truck)


Upgrade to Eurotherm Temperature controller
OTF-1200X-RTP-4-SL is an RTP (4'' OD) furnace with Infrared Light Heating and Slide Cooling. 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 graphene and carbon nanotubes by CVD.


Furnace Structure
  • Double layer steel casing with air cooling keeps furnace surface temperature lower than 60°C.
  • 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.


Voltage AC 208-240V Single Phase, 50/60 Hz
Max. Temperature
  • 1000°C (<1 hour)     
  • 800°C (<2 hours)
  • 600°C (continuous) 
Note: RTP furnaces should not be heated for long durations due to thin refractories.

2.8°C/sec (500°C - 400°C);
1.6°C/sec (400°C - 300°C);
0.9°C/sec (300°C - 200°C);
Process Tube Size High purity fused quartz tube
Ø4" OD x 1400mm L  
Sliding Rails / Table
  • Dual sliding rails made of Cr plated steel
  • Sliding rail length: 1200 mm
  • Driven by DC motor
Sliding Control
Automatic sliding is controlled by the temperature controller.  When the heating program is finished, the furnace will slide from right to left at the set speed. Air fans will blow heated area to achieve fast cooling.
  • Sliding Range: 340mm
  • Sliding Speed: 0-70 mm/s; adjustable
Heating Elements
8 pcs Paralleled Infrared Heating  ( 1200w each)
K type, 1/4" Dia x 24" length

Temperature Controller

  • PID automatic control with 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
  • Built-in overheating & thermocouple broken protection.
  • Over temperature protection and alarm allows for operation without attendant(s).
  • +/- 1 ºC temperature accuracy.
  • RS485 Communications Port.
  • PC Control:  
    • An MTS-02 control module is included for PC control on this furnace.
    • The new version of PC module is now compatible with Lab View 05/08/2014
    • 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 click here.

Vacuum Flanges

Stainless steel vacuum flanges are installed on both ends of the tube.

Right flange:
  • Hinge-type flange for easy sample loading
  • 1/4"diameter  feedthrough for inserting  K-type thermal couple
  • Needle valve with barb gas fitting is built in
Left flange:
  • Digital vacuum gauge is included
  • KF25 right angle valve is installed for connecting to a vacuum pump
  • Needle valve for vacuum release is included

Vacuum Level 

 Limited by vacuum pump
  • 10^-2 torr can be achieved by mechanical pump
  • 10^-4 torr can be reached by molecular pump
 Vacuum pump is not included, please order separately at related products section

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.
