High-Temperature Laboratory Cupellation Furnace for Precious Metal Fire Assay up to 1200℃
This cupellation furnace is specially designed for the cupellation stage of fire assay, providing stable and uniform heating conditions for the accurate determination of precious metal content. It is widely used in laboratories, mining companies, refineries, jewelry testing centers, and geological research institutes.
During the cupellation process, lead is oxidized and absorbed by the cupel, leaving a precious metal bead for subsequent analysis. The furnace offers excellent temperature uniformity and reliable airflow to ensure complete oxidation and consistent assay results.
The maximum operating temperature is 1200°C, making it ideal for the analysis of gold, silver, platinum group metals, ores, concentrates, recycled precious metals, electronic scrap, and jewelry alloys.
