    Heating elements on support tubes radiating freely into the furnace chamber provide for particularly short heating times for these muffle furnaces. Thanks to their robust lightweight refractory brick insulation, they can reach a maximum working temperature of 1300 °C. These muffle furnaces thus represent an interesting alternative to the familiar L(T) ../12 models, when you need a higher application temperature. 

    • Tmax 1300 °C · Heating from two sides · Heating elements on support tubes ensure free heat radiation and a long service life 
    • Multi-layer insulation with robust lightweight refractory bricks in the furnace chamber 
    • Optional flap door (L) which can be used as work platform or lift door (LT) with hot surface facing away from the operator 
    • Adjustable air inlet in the furnace door · Exhaust air outlet in rear wall of furnace · Controller B410 (5 programs with each 4 segments)
