Detailed
Specific Introduction:
    KJ-1500X-Z8 is an open tube furnace with 8 temperature zones, equipped with mullite furnace tubes and stainless steel sealing flanges, and the maximum working temperature of the furnace body can reach 1500℃. The heating element is a SiC rod, and each temperature zone is controlled by an independent temperature control system, which can form a variety of temperature gradients in the furnace tube to meet various experimental requirements. Such as gradual functional materials, high-throughput methods to study phase change and recrystallization.

  • 3 pcs S type thermal couple built in
Net Weight 110 Kg

Application Notes
  • The tube furnaces with mullite tube are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI 
  • Never use graphite crucible in alumina tube.
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
  • The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
  • Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1300°C
Dimensions Furnace only: 35" × 23" × 30"


Warranty
  • One year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.).  
  • ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of Kejia One Year Limited Warranty.
