Dual Heating Zone 1200C Compact Split Tube Furnace

Dual Heating Zone 1200C Compact Split Tube Furnace

Model:KJ-1200X-S-II

Description:

KJ-1200X-S-II is a UL certifiable compact two heating zone split tube furnace with a max. the working temperature of 1200°C. The furnace can adopt either a 1" or 2" O.D quartz tube (optional) with a pair of stainless steel vacuum sealing flanges. The 1/4" barb fitting for rubber hose connection allows heating samples in a vacuum or flowing gas.

Detailed
Specific Introduction:
    KJ-1200X-S-II is a UL certifiable compact two heating zone split tube furnace with a max. the working temperature of 1200°C. The furnace can adopt either a 1" or  2" O.D quartz tube (optional) with a pair of stainless steel vacuum sealing flanges. The 1/4" barb fitting for rubber hose connection allows heating samples in a vacuum or flowing gas. The furnace has two 4" L heating zone, which can provide a 100 mm long constant temperature zone or 200°C temperature gradient. Built-in two precision temperature controllers can provide up to 30 segments of heating and cooling steps with +/- 1°C accuracy.
Parameters:

Furnace Structure
  • Double-layer steel structure.
  • High purity Al2O3 fibrous insulation with Max. energy saving
  • High purity alumina coating on refractory ceramics for longer service life.
  • Two 4" length heating zone which can be controlled by temperature independently.
  • Dual Heating zone design and Alumina circle block help you build customized Temperature Gradient inside the tube.
  • All electric components (>24V) are UL certified and ready to pass TUV, CSA, and UL test
Power 
  • 110V AC, single phase, 50/60 Hz
  • 1.5 KW
Max. Temperature 1200°C (<1 hour)
Continuous Temperature 1100°C ( continuous)
Max. Heating Rate ≤ 20°C/min
Heating Zone Length
  • Two heating zone and each zone length is 100mm and 200 mm in total 
Constant Temp. Zone

&
Temperature Gradient
  • 50mm  within +/-1°C ( If set two zones at the same temperature )
  • 70mm  within +/-2°C  ( If set two zones at the same temperature )
  • Max. temperature gradient :  1°C/ mm ( one zone heating )
  • Max. temp difference between the adjacent zones ~100°C (heat up one zone only, without the isolator between the adjacent zones)

Temperature Controller
  • Two temperature controllers are built to control the heating zone independently via K-type thermal couples
  • PID automatic control via solid-state relay with 30 steps programmable
  • Built in Over Temperature and Thermocouple Failure Protection
Temperature Accuracy +/- 1°C
Heating Elements Fe-Cr-Al Alloy doped by Mo

Tube Size

Please select the tube size in the options bar, ( click below to order spare tube )
 1" quartz tube (25mm O.D x 22mm I.D x 450mm L)
  • Two fibrous ceramic tube blocks are included 
  • Quartz blocks (optional) are ideal for clean & Hight vacuum 
  • May order flange support to avoid tube rotating.
2" quartz tube (50mm O.D x 44mm I.D x 600mm L) 
Two fibrous ceramic tube blocks are included for blocking heat radiation from the tube chamber. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
 
 
 
Vacuum Flanges
1" flange has no thermocouple insert 2"  and 2.36"(Option) tube flange
Vacuum Level 10-3torr (by mechanical pump)
Fitting Ports
       &
Optional Parts
  • You may need a vacuum valve at the vacuum port
  • You may consider ordering quick connecting flange at extra cost.
  • You may contact us to order the furnace with a vacuum pump and a temperature calibration kit.
Pressure Measurement & Monitoring
  • Standard mechanical vacuum gauge measures within a pressure range of -0.1 to 0.15Mpa is included.
  • OPTIONAL: A gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr. Aside from greater measurement precision, this gauge reduces risks of chamber explosions caused by the incorrect reading of gas pressures due to gas-type dependency.

Compliance
  • CE Certified
  • NRTL or CSA certification is available at extra cost. 
Application Notes & Warning
 
  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°C
  • Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation.
