Product Description
  • Programmable laboratory 1200 degree muffle furnace

ZKM 1200 series muffle furnace features high quality spiral wire coils embedded in Mitsubishi (Japan) high quality alumina fiber insulation. A double walled steel internal housing helps minimize heat loss to exterior surface. Laboratory furnaces are ideal for heat treating, reacting studies, sintering processes, and ceramic firing. Our laboratory furnaces feature temperatures up to 1800 degrees Celsius and capacities up to 45 liters. Important specifications to consider when searching for a laboratory furnace include the process temperature, control requirements, dimensions of sample and inner dimensions of chamber or tube, and pressure range.


Furnace operation is controlled by Shimaden (Japan) 32-segment digital controller with temperature accuracy of +/- 1 C degree. Proper temperature control is vital to the success of your project as well. Temperatures that are too high or too low will cause problems with the process and could cost your company a significant amount of money.

Usage The product is suitable for elemental analysis, measurement and small size steel hardening, annealing, tempering, heat treatment and heating in laboratory, industrial and mining enterprises, scientific research units,can also be used for sintering of metal, stone, ceramic, dissolution analysis of high-temperature heating.
Furnace structure The furnace is made of carbon steel with powder coating on surface, integrate furnace body and heating system and controller system in one
Max. temperature 1200°C (2192°F)
Continuous Working temperature 1100°C (2012°F)
Heating Rate Fast heat-up time due to the low thermal mass construction
Suggest 5~15℃/min for longer life using of furnace
Heating Element Top brand iron-aluminum alloy resistance coil wire (HRE)
The wire elements are coiled and embedded in three sides of the wall (Elements located in ceiling, left and right sides)
Chamber material 1. Adopt high quality alumina polycrystalline fiber, which used Japanese technology (vac-sorb forming alumina polycrystalline fiber) with good insulation and durability properties
2. High quality 1300 degree fiber alumina as refractory lining, pure white color
3. Ceramic fiber insulation for fast heat-up and reduced energy consumption—rise time to 1100°>C takes only 50 minutes
4. Embedded heating elements on the round chamber which give an ideal temperature uniformity
Temp. Uniformity ±5°C
