Item Number: OTF-1200X-S-HPCVD
Transported by LTL Freight (Truck)
OTF-1200X-S-HPCVD is a compact 2" split tube furnace with internal sample traveling system inside the processing tube. This allows the position & temperature control of the sample stage or crucible via touch screen digital controller.  It is designed for multi-functional rapid thermal processing, such as hybrid physical-chemical deposition(HPCVD), rapid thermal evaporation (RTE), and as well Horizontal Bridgman Crystal Growth ( HDC) under various atmosphere for new generation crystal research.

Max. Heating & Cooling Rate

The max heating and cooling rate can be achieved by moving sample into pre-heated hot zone and move the sample out from hot zone.  The typical ramp/cool rate is listed in below:
  Heating Rate:
 10°C/sec (150°C - 250°C);
  7°C/sec (250°C - 350°C);
  4°C/sec (350°C - 500°C);
  3°C/sec (500°C - 550°C);
  2°C/sec (550°C - 650°C);
  1°C/sec (650°C - 800°C);
  0.5°C/sec (800°C - 1000°C);
Cooling Rate:
10°C/sec (950°C - 900°C);
7°C/sec (900°C - 850°C);
4°C/sec (850°C - 750°C);
2°C/sec (750°C - 600°C);
1.5°C/sec (600°C - 500°C);
1°C/sec (500°C - 400°C);
0.5°C/sec (400°C - 300°C);

One year limited warranty with lifetime support (Consumable parts such as processing tubes and o-rings are not covered by the warranty,) 


Compliance
  • CE Certified
  • All electric components ( >24V) are UL / MET / CSA certified

Warning


  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa
  • 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.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C

Application Notes This multi-functional furnace is suitable for the applications in below:
  • RTE:  Crucible loaded with evaporation material is placed in the center of the furnace, move sample holder to a downstream position with appropriate temperature where the deposition takes place.
  • HPCVD: Similar setup as RTE, we also introduce reactant gas to mix with evaporation vapor and make deposition
  • Horizontal Bridgman Crystal Growth:  Load material and seed into a crucible and place it in the center of the furnace. Move the crucible at the desired speed to grow single crystal under suitable thermal gradient.
  • If you have any question and suggestion, please contact us before purchasing
  • 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.
