Product Options

Tube Diameter:


  OTF-1200X-IV-OD is a Four-zone split tube furnace that can create a smooth thermal gradient or one uniform constant temperature zone by adjusting the four-zone temperature up to 1200oC with a 900 mm long heating zone. The furnace includes one quartz tube with optional OD of  80, 100, or 130 mm OD, and one pair of vacuum sealing flanges with pressure gauge & ball valve for immediate use. 
   Touch Screen temperature controller is installed for easy programming with 30 segments and
 +/- 1 oC accuracy. It is an excellent furnace for annealing, diffusing, and sintering samples in various atmospheres.   


Furnace structure

  • Double-layer steel case with two cooling fans, which ensures the low surface temperature.
  • Energy-saving high purity fibrous alumina insulation.
  • AC 208-240V Single Phase, 50/60 Hz (50A breaker required)
  • Power consumption: 7 KW Max.
  • A power cord is included without the plug
  •  Max.                          1200  oC < 1 hr.
  • Continuous :               1100  oC
  •  Max. Heating Rate:   <= 20  oC /min
 Quartz Tube

  • Three Types of quartz tubes are available as in product option 
    • OD 80 x  ID 74 x L 1400  ( mm)
    • OD100 x ID 94 x L 1400 ( mm)
    • OD 130 x ID 124 x L 1400 ( mm) 
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from inside the tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
  • Quartz block (Optional) is ideal for more cleanness and higher achievable vacuum.


 Vacuum -Tight Flange

  • One pair of the vacuum-sealed flange is included for matched tube
  • The needle valve is installed on the right-side flange with 1/4" tube fitting
  • The mechanical gauge and valve is installed in the left-side flange
  • Vacuum level: 10-4 torr by turbopump and 10-2 torr by a mechanical pump
  • A digital vacuum gauge (Pic. 1) and KF25 port are available upon request at extra cost
  •   Pic. 1 Pic. 2
Heating Zone Length
  •  Four heating zones:    150+300+ 300+ 150 (mm), intotal 900 mm length
  • Constant temperature zone:  450mm within +/- 2 oC ( if set 4 zone in same temperature )
Temperature Control

  • Four temperature controllers are integrated into a touch screen control panel to set temperature profiles easily, which can control each heating zone independently  or heating 4 zones at the same temperature
  • PID automatic control for heating rate, cooling rate, and dwell time up to 30 segments
  • Built-in overheating & broken thermocouple protection.
  • +/- 1 ºC temperature accuracy.
  • Four K-type thermocouples (one for each zone).
  • RS485 Communications Port  and soft are available for PC connection
