Laboratory Muffle furnace Application:
Muffle furnace/oven mainly used in chemical analysis, physical decomposition and synthesis,
super hard materials (such as ceramic), Rare and precious metal smelting and purification,
metal heat treatment of sintering process research and other scientific experiments.
Universities and colleges, scientific research institutes, medical and health, petroleum chemical
industry, mining enterprise, quality and technology supervision agencies,
and other units laboratory, laboratory are the use of such equipment.
1. Gravimetric analysis;
2. Sintering;
3. Quantitative analysis;
4. Heat treating;
5. Glass preparation;
1800 degree ceramic electric sintering furnace is our main product-Muffle furnace.The Muffle furnace consists of high quality alumina fiber and MoSi2 heating elements with special design,and furnace temperature controlled by high precision SCR (Silicon Controlled Rectifier) digital controller with accuracy ±1 degree and 50 segments programmable.
The furnace widely used for materials annealing,ceramic sintering ,melting and most heat treatment experiments in your research laboratory.

Muffle furnace Using Precautions:
1. The MoSi2 heating element must not be used at low temperatures (400.C-700.C) for a long
time, otherwise the heating element may be damaged.
2. In order not to affect the service life of the instrument, we recommend the heating rate <10°C/min and cooling rate < 5°C/min.
3. The box furnace does not use vacuum sealing structure, so can not inlet flammable or explosive gas.
4. After using the furnace a certain period, there will be minor cracks in the
hearth/chamber. This is a normal phenomenon and will not affect the use.
At the same time, it can be repaired with an alumina coating.
5. Door block/Firebricks must be inserted before closing the furnace door.
Regular chamber size: 100x100x100mm,150x100x100mm,150x150x150mm,200x150x150mm,200x200x200mm,
300x200x200mm,400x300x300mm or customized.
