Specialized for the classical determination of noble metals by fusion and cupellation
Complete Fire Assay Solutions from Lab to Industry
Our fire assay furnaces are engineered to deliver precise temperature control and stable thermal environments for accurate gold and silver determination. Designed to meet the demands of laboratory research and industrial-scale sample testing, these furnaces support the complete fire assay process, including fusion and cupellation.
With years of experience in fire assay system development, we provide not only reliable heating equipment but also complete solutions for assay laboratories. Each furnace features programmable temperature controllers (±1°C), durable insulation materials, and optimized chamber design to ensure consistent results across repeated cycles.
We offer both fusion and cupellation furnaces in standard and custom configurations, suitable for mining labs, refineries, and third-party testing centers. Auxiliary equipment—such as cupels, scorifiers, crucible holders, tongs, and ventilation systems—is available to support full-system integration.
Whether for routine sample analysis or high-throughput metallurgical testing, our fire assay furnace systems provide stable operation, high safety standards, and long-term durability to support demanding precious metal workflows.
