8-10 wks delivery
Item Number: OTF1200XSDFPESL
Transported by LTL Freight (Truck)
OTF1200XSDFPESL is a dual slidable PECVD (Plasma Enhanced Chemical Vapor Deposition) tube furnace system. It is a tool for PECVD with 2" ODx55"L Quartz tube & flanges and a max 1200°C achievable working temperature. Two 2" tube furnaces can be slide on the sliding rail to find positions for source materials thermal evaporation/sublimation and film deposition. Sliding the furnace from one side to another can achieve max. heating and cooling rates up to 100°C/min. 


Furnace Structure

  • Both furnaces are double-layer steel structures with 1200°C max. working temperature.
  • Each Furnace has a 200mm heating zone and a 60 mm long constant temperature zone.
  • One pair of sliding rails are installed on the bottom of the furnace, which allows the furnace to be manually moved from side to side with a max sliding distance 400 mm.
  • Vacuum flanges are installed for immediate use.

Power of furnace

  •  AC 208-240V Single Phase, 50/60 Hz, 20 A air breaker required
  •  2.5 KW in total

Max. Temperature

  • 1200°C (<1 hour)

Continuous Temperature

  • 1100°C

Heating & Cooling Rates

  Heating Rate:
 15°C/sec (RT - 150°C);
 10°C/sec (150°C - 250°C);
  7°C/sec (250°C - 350°C);
  4°C/sec (350°C - 500°C);
  3°C/sec (350°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:
15°C/sec (1000 - 950°C);
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);
The max heating and cooling rate is achieved by pre-heat one side of the processing tube to the target temperature and then slide the furnace to the other side. You may choose to place the sample in the pre-heat area or not.
