FEATURES
  • Maximum operating temperatures of 1700ºC and 1800ºC.
  • Three chamber sizes are available.
  • Convenient loading of chamber through electrically actuated lift mechanism.
  • Superior sample uniformity is obtained by positioning elements on all sides of hexagon shaped chamber.
  • All standard 1700ºC and 1800ºC BLF furnaces are fitted with 3216P1 programmer and a separate independent over-temperature protection control.
  • Elevator hearth design provides safe and smooth loading and unloading of delicate loads.
  • Fast heating and cooling of the sample is achieved by raising or lowering the sample from the furnace chamber.
  • Long-life molybdenum disilicide heating elements are suitable for intermittent or continuous operation.
  • Advanced high temperature, high strength hot face insulation is combined with graded low thermal mass insulation to improve thermal performance and energy efficiency.
  • A positive break safety switch isolates power to the heating elements when hearth is lowered.
  • The Chamber vent provides for process exhaust.
  • Large diameter heating elements greatly reduce the potential for mechanical breakage.
  • Low temperatures of the outer case and critical components are provided through fan cooling.
  • Molybdenum disilicide element resistance does not change with usage, providing any restriction on the placement of a new element in a circuit with older elements.
  • Optional gas containment cover allows processing under high purity inert atmospheres.
  • Optional protective alumina liner is available for aggressive processes that may harm elements or insulation materials.
