Vertical Two Zone Tube Furnace

  • Compact two zones split vertical tube furnace
  • Working Voltage: 110V AC or 220V selectable
  • Max. Power Consumption: 1.5 KW
  • Two Heating Zone: 100 mm L for each Zone, 200 mm L in total 
  • Max. heating temperature: 1200°C
  • Continuous working temperature: 1100°C
  • Two programmable digital temperature controllers which control two heating zone independently
  • Max. Temperature gradient: 1ºC/Cm
    • Finding a suitable thermal gradient is user responsibility
    • Adjusting two heating zone's temperature can create different thermal gradient profile
    • Adjusting furnace opening diameter also can change the thermal gradient
  • Quartz tube (2" quartz tube (50mm O.D x 44mm I.D x 600mm L) is included with sealed flange)
  • Click Pic left to see detail specs of the dual-zone furnace
Hanging wire

  • One set of Ni-SS hanging wire is included (pic to the left). Max. working temperature is 800C.
  • Optional hanging wire for higher working temperature is available upon request:
    • Ni-Cr-Al wire (not included) Max. working temperature < 1100°C
    • Platinium wire (not included) Max.working temperature > 1200°C and < 1600°C
  • A thin hanging wire goes through the top flange. A positive inert gas can keep processing tube under controlled atmosphere
  • For air-sensitive material, the sample shall be sealed in a small quartz tube with pre-vacuumed as Pic below right
  • 800C pulling wire (Ni-SS)        sealed quartz tube as the crucible
