Description
Cupel 6HB Tapered – High Precision Magnesia Cupel for Fire Assay
The Cupel 6HB Tapered from Mechelec is designed for precision and durability in fire assay applications, especially in the analysis of gold and silver. Manufactured from high-quality magnesia material, this tapered cupel offers superior absorption of lead oxides and delivers consistent assay results with minimal contamination.
The tapered design enhances efficiency by concentrating heat toward the center, which helps maintain an optimal reaction zone during cupellation. This feature is particularly valuable in high-volume laboratories where consistency and repeatability are crucial. The magnesia-based structure allows the cupel to withstand temperatures exceeding 1200°C, making it ideal for demanding assay workflows.
Engineered to maximize porosity without sacrificing strength, the Cupel 6HB Tapered quickly absorbs litharge, leaving behind clean metallic beads for precise weighing. It is suitable for use in both traditional and modern muffle furnaces, as well as automated assay systems. The dimensions and tapered profile allow for stable placement and easy retrieval post-firing.
Commonly used in hallmarking centers, refineries, and mining exploration labs, this cupel supports a broad range of fire assay protocols. Whether you are working with ore samples, bullion, or recycled jewelry, it provides consistent separation of base metals from precious ones.
