1200C Dual Zone Split Tube Furnace w/ Quartz Tube (60, 80, 100mm) & Flanges - OTF-1200X-II

Transported by LTL Freight (Truck)

Product Options

Tube Size:


Upgrade to Eurotherm Temp Controllers (Dual )
OTF-1200X-II-UL is a Split two-zone tube furnace which can achieve faster heating up to 1200oC and create a different thermal gradient by setting the different temperatures of each zone. The furnace includes one 40" L fused quartz tube (please select tube O.D in options bar) with vacuum flanges and valves for immediate use. Two 30 segments of programmable temperature controllers are installed. The microprocessor-based self-tuning PID controller provides excellent control without overshooting the set temperature. It is a perfect tool for CVD applications such as preparing nanomaterials and film.


Furnace structure

  • Double-layer steel case with two cooling fans, which ensure low surface temperature
  • Energy-saving high purity fibrous alumina liner and  insulation
  • High purity Al2O3 coating  which provides a longer service life
Power 3 KW (20A Breaker)
Voltage AC 208-240V Single Phase, 50/60 Hz, a power cord is included without the plug.
Temperature range 100~1100° C (Continuous); 1200° C (<1 hour) 
Max. Heating Rate ≤ 20° C /min
Tube Accessories (When the tube size is selected, compatible accessories will match it automatically, please refer to standard package for details)
  • One fused quartz tube with 1000mm L is included 
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside 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, available at extra cost
  • You may order flange support to avoid tube rotating ( click Pic below right )

Heating Zone Length

Constant Temp. Zone
  • 150mm (+/-1°C) for each heating zone
  • A longer constant temperature zone ( about 200mm ) can be created by setting both zones at the same temperature 
  • Please click the pic to view the detailed temperature uniformity profile at 800C.

Temperature Controllers
  • 2 MET certified digital controllers with 30 programmable segments for precise control of heating rate, cooling rate and dwell time
  • Built-in PID Auto-Tune function with overheating & broken thermocouple protection
  • Over-temperature protection and alarm allows for operation without attendant(s)
  • +/- 1 ºC temperature accuracy
  • Two K-type thermocouples (one for each zone)
  • RS485 Communications Port
  • Optional:  
    • The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at an extra cost
    • If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer laptop from us 
Thermal Couples
Temperature Accuracy +/- 1° C
Heating Element Fe-Cr-Al Alloy doped by Mo
Vacuum Flange & Fitting Ports
(Certain flange size will be matched as the tube size is selected in options bar)
  • One pair of SS 304 vacuum flange with double high-temperature silicone O-rings are Included
  • One Vacuum pressure gauge is installed, one digital vacuum gauge is available upon request at an extra cost
  • The flange set has two 1/4'' Bard fittings, two-needle valve, one set of KF25 quick clamp, one blank flange fitting, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert) and a KF25 vacuum port (click the picture in the left to see details)
  • The vacuum level can reach 10^-2 torr by a quality mechanical vacuum pump and 10^-5 torr by a molecular pump
  • Optional: Please choose quality mechanical pump or molecular pump (please click the pictures below to find the right one for your application)
