Presto’s muffle furnace is used to evaluate the ash content of a test sample. The percentage of ash in a component provides vital insights into the properties of the material. The instrument is designed keeping in mind IS and ASTM standards. The testing instrument is widely used in various fields like agriculture, metal treatment, medical research, agricultural, rubber and wool industries.
Coming up with the elegant design, the range of muffle furnace are easy to operate and install. Just send your desired process temperature and digital controller will heat and control the furnace automatically. Our furnace models are designed for various applications like ashing various types of organic and inorganic test specimens and mold heating, etc. The muffle furnace is shielded with thermal efficient products for energy and cost saving operations.
The testing instrument is used to calculate the percentage of ash same as the index of added mineral loading. To perform the test, weight a piece of specimen. Now burn the specimen and weight the ash of the burnt sample and calculate the percentage easily. The test procedure involves tearing the specimen in small grates and place it in the already weighed crucible. Now check the weight again.
Now carefully heat the crucible over a Bunsen burner to certain that the paper burns until it is fully burnt. After performing this, transfer the crucible into a presto muffle furnace at 800+25. C or as per the set standards and generate the heat in the furnace until all the carbonaceous matter is burnt off.
Now cool down the crucible in desiccators and measure its weight. Repeat the operation until the weight become constant.
How to calculate the ash content?
Ash, % by weight = 100 a-x/b-x
A= Weight in gram of the crucible and the ash (w3)
B= weight of the crucible and the material (W1) (in grams)
X= weight of the crucible (W2) (In grams)
