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

Personalization

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.
 

SPECIFICATIONS

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.
             

Power

9KW
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.
Temperature Accuracy
+/ - 2°C
Max. Heating Rate
50  ºC/s
Max. Cooling Rate
Cooling Rate from 900~200C:
8.3°C/sec (900 - 600°C);
4.4°C/sec (600°C - 500°C);
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)
Thermocouple
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.

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.
