SKJ-BG-1200 is a small 1200ºC Bridgman crystal growth furnace with a 72 mm ID quartz tube and precision travel mechanism, which is designed for growing small size crystals under control atmosphere up to 1200oC


SPECIFICATIONS:

Vertical Two Zone Tube Furnace
  • Compact two zones split vertical tube furnace
  • Working Voltage:  208 - 240V selectable
  • Max. Power Consumption: 4.0 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 the user's responsibility
  • Adjusting two heating zone's temperatures can create different thermal gradient profile
  • Adjusting the furnace opening diameter also can change the thermal gradient
  • A quartz tube (80mm O.D x 72mm I.D x 800mm L) is included with an airtight flange)

Travel Mechanism
  • DC motor with precision screw drives the furnace up or down for crystal growth
  • Travel distance:  200 mm Max.
  • Travel speed range:  0.03 mm /hr. -  30 mm /hr. adjustable with +/- 1 micron accuracy ( standard)
  • Customized speed range is available upon request
Airtight Flanges
  • One pair of air-tight flanges is included for atmosphere control under a vacuum
  • The top flange has a mechanical vacuum gauge and 1/4" gas inlet
  • The bottom flange has a KF25 vacuum port and 1/4" gas outlet 
  • Vacuum level:  10-2 torr by mechanical pump and 10-5 torr by a turbopump
  • Please click the picture below to order a vacuum pump
Control Panel
  • A touch screen control PC is included for control travel speed, travel distance,  temperatures of the furnace and crucible temperature separately, as well as gas pressure inside the tube.
  • Two Eurotherm controllers and two K-type thermal couples are included with +/- 0.1 oC accuracy
  • One thermal couple controls the temperature of the furnace 
  • One thermal couple displays the temperature of the crucible at its bottom
  • One digital pressure sensor with solenoid valves is installed for controlling tube pressure at the constant from 0.01MPa - 0.02MPa
  • Click the picture left to see the PC interface
Optional
  • 10E-2 torr via dual-stage mechanical vacuum pump (Pic. 2)
  • 10E-5 torr via Turbopump (Pic. 1) 
  • The vacuum pump is optional. Please click here to choose a vacuum pump. 
  • For oxygen-sensitive material, suggest using a recirculating gas purification system ( H2O, O2 < 1 ppm) to replace the turbopump (Pic. 3)
