Muffle Furnace

“Muffle Furnace” manufactured by International Equipment is a very compact laboratory furnace that can rise up to a temperature of 1000 degree Centigrade. These furnaces normally come with size 4 inch x 4 inch x 9 inch deep and 6 inch x 6 inch x 12 inches deep. Muffle furnace is used to check Ash percentage in polymers. The working is very simple. Granules around 2 to 3 grams are first weighed on an accurate weighing scale to the nearest value of 1 mg and further burnt fully in the furnace at 800 degree Centigrade.

After burning and once thefurnace is settled to ambient temperature the remaining residual with crucible is again weighed. Finally percentage of ash is mathematically calculated. Muffle furnace is very useful equipment required in the polymer laboratories.
