Ash Determination Muffle Furnace

The ash determination muffle furnace achieves ashing by heating the sample at high temperatures, causing organic matter to combust and decompose, with the residual inorganic material constituting the ash. It is used to measure the inorganic content in materials and control the purity of raw materials in industries such as coatings and plastics.
Selection
When selecting, consider that the temperature range must cover the ashing temperature, the furnace chamber size should match the sample volume, temperature control accuracy affects result repeatability, material corrosion resistance extends service life, and safety features include overheat protection and power-off recovery.
