BLF – High Temperature Bottom Loading Furnaces

BLF bottom loading furnaces use an electrically operated elevator hearth, which as it rises into the furnace chamber, lifts the load into the heated zone.

Categories: ,


This furnace provides the following advantages: easy loading of samples and uniform heating achieved by locating elements in all six side walls of the chamber.

  Standard Features
•  1600°C, 1700°C & 1800°C maximum operating temperature
•  3 to 21 litre capacities
•  1600°C model heated by silicon carbide elements
•  1700°C & 1800°C models heated by molybdenum disilicide elements
•  Excellent temperature uniformity as a result of the hexagonal chamber
•  Electrically operated elevator hearth protects operator from the chamber’s radiant heat
•  Hearth cage with safety interlock
•  Ideal for: sintering high performance ceramics, melting glass under high temperature or working with modified atmospheres
•  Over-temperature protection to protect load or furnace during unattended operation
•  Programmable 3216P1 controller
•  Rapid heating & cooling cycles can be achieved through raising & lowering the hearth

  Options (specify these at time of order)
•  A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
•  Compatible crucibles
•  Customised options including: adaptation to introduce thermocouple or stirrer through the chamber roof and rotating hearth
•  Modified hearth for the introduction of gases into an inverted crucible (not gas tight)
•  Plasma sprayed alumina protection tube to protect heating elements from sample contamination
•  Radiation shutter
