2200ºC Top Seeded Solution Growth (TSSG) Furnace - VTF-2200X-TSSG

Please email for lead time
Item Number: VTF-1600X-TSSG
Transported by LTL Freight (Truck)

VTF-2200X-TSSG is an ultra-high temperature TSSG (top seed solution growth) furnace for growing SiC or Sapphire via flux solution at 2000 degrees. The furnace is heated by an induction coil with a 4" dia graphite crucible and an 8" dia. hermetic quartz chamber. Temperature is detected by a type C thermocouple and controlled by a Eurotherm 3000 series temperature controller. It also equips a precision pulling device with a minimum pulling rate of 0.6 mm/hr and a minimum rotation speed of 0.1 rpm. It can be operated under vacuum, inert gas flow, or reducing environment. 

  • 208 - 240VAC, three phases, 50/60Hz
  • 17 kW Max. A 60 A power panel is required. 
  • 10 feet long 6/4 AWG UL-approved power cable is included. 
  • The power plug is not included. Compatible plugs are available here.
