Compact Split Tube Furnace with Insert-able Temp Calibrator and Complete Vacuum System

Model:KJ-1200X-S

Description:

KJ-1200X-S-50-LVT high-temperature vacuum tube furnace is a split tube furnace for heating samples up to 1200°C. KF25 Gas Outlet and Digital Vacuum Gauge on the right flange connecting a 226L/m Mechanical Pump and Pump Filter while 1/4'' barb gas inlet on the left, allows the furnace to heat the sample in vacuum up to 1E-2 Torr or flowing gas.

Detailed
Specific Introduction:
    KJ-1200X-S-50-LVT high-temperature vacuum tube furnace is a split tube furnace for heating samples up to 1200°C. KF25 Gas Outlet and Digital Vacuum Gauge on the right flange connecting a 226L/m Mechanical Pump and Pump Filter while 1/4'' barb gas inlet on the left, allows the furnace to heat the sample in vacuum up to 1E-2 Torr or flowing gas. In addition, OMEGA 1/4’’ O.D K Type Thermal Couple comes to the left flange, can be inserted inside the tube to exactly measure the sample’s temperature by the readout from the OMEGA Calibrator. The precision temperature controller will provide 30 segments of heating and cooling steps with +/- 1 °C accuracy.
Parameters:
Furnace casing Heavy-duty steel casing
Energy-efficient Al2O3 fibrous thermal insulation
Total Power 1.75 KW
Voltage AC 110V, Single Phase, 50/60 Hz
208V-240V version is available upon request 
Max. Temperature 1200 °C (<1 hour)
Continuous Temperature 1100 °C ( continuous)
Max. Heating Rate <= 10 °C/min
Tube Size and Materials OD: 50;  ID 43:  Length: 600  mm
Heating Zone length 8" (200mm)  ( single zone ). 
Thermal block placement
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from tube chamber. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
  • Quartz blocks (optional) are ideal for cleaner and higher vacuum efficiency.
  • You may order flange support to avoid tube rotating.
     
Constant temperature zone Length 2.3" (100mm)  (+/-1°C) @ 900 °C
 
Temperature controller PID automatic control via PWM solid relay with 30 steps programmable.
Temperature Accuracy +/- 1 °C
Vacuum Flange SS Vacuum Flanges (Left with 1/4 barb fitting and TC feed through, right with KF25 fitting Vacuum Gauge)
Vacuum Level 1E-2  ( 50 m-torr)  by included Double Step Rotary Vane Vacuum Pump (110V, 226 L/m) with Exhaust Filter & KF-D25 Inlet  with Vacuum Bellows and KF25 Clamp
Heating Element Fe-Cr-Al Alloy doped by Mo
Temperature Calibrator Thermal Couples: K type 18" x 1/4"Dia with Alloy sheath and Male Plug for Calibration up to 1335°C
Portable Digital Temperature Calibrator with USB and RS232 Interface & Software - NIST certificate            
Optional
  • This furnace can be updated to 60 mm quartz tube with quartz observation window  at the extra cost
  • For Vacuum to 10E-6 torr, you may consider turbopump with CF flange and one end open quartz tube.                           
Dimension 340 × 300 × 400 ( W x L x H)
Net Weight 60 lbs (furnace only)
Shipping Weight 150 lbs
Warranty One-year limited warranty (Consumable parts such as processing tubes, o-rings, and heating elements are not covered by the warranty, please order the replacement at related products below.) 
Application Notes


 
  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02MPa
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
  • The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
  • For safety, you may consider putting the small tube furnace inside a fume hood.
Certificate The furnace is ready to pass UL 61010, IEC 61010, SPE-1000 tested by NRTLs at extra cost.
