Muffle furnace

Application

The Muffle furnace M 110 is used for the determination of ash in cereals and cereal products. Ash is defined as the quantity of mineral matter remaining as an incombustible residue of the sample upon completion of the ashing process.

Temperatures of 300 °C up to 1100°C can be set for different applications.

Principle

Weigh the test substance, which may have to be preground, into crucibles, and place them into the muffle furnace. The ashing is carried out and is completed when the cool residue is white or nearly white.

As the ash content refers to dry matter, first the moisture content of the sample material must be determined in a separate step.

Temperature protection

The Muffle furnace is equipped with a radio interference suppression and the door with a door-operated safety switch.

The unit is supplied with an electronic upper limit cut-out (TWB) with sensor defect recognition, temperature class 2 to DIN standard 12 880 Section 1/11.78. It is electrically and functionally independent of the temperature control system.

Advantages

Reference method approved worldwide for a large variety of raw materials.
