Multi-Fuel Cupellation Furnace

Key Advantages

Low Power Dependency: Multi-fuel cupellation furnace can operate stably in areas with insufficient power supply, unstable grid voltage.
Precise Temperature Control: The optimized furnace cavity design creates a uniform temperature field, ensuring consistent cupellation effects for all samples in a single batch.
Flexible Fuel Compatibility: Each specification is available with LPG, natural gas, and diesel fuel options.
High Thermal Efficiency: The direct flame heating structure delivers high thermal efficiency, enabling the furnace to reach rated operating temperature in a short preheating period.
User-Friendly Operation: The pneumatically controlled door system reduces manual labor intensity during operation.
Industrial-Grade Reliability: The multi-fuel cupellation furnace cavity is constructed with high-temperature resistant and corrosion-resistant refractory materials.

Multi-Fuel Cupellation Furnace

The multi-fuel cupellation furnace series is a purpose-built industrial solution engineered specifically for the critical cupellation stage within precious metal fire assaying and refining workflows. Developed as an innovative alternative to traditional electric resistance units, this advanced multi-fuel cupellation furnace utilizes gas (LPG or Natural Gas) or diesel as its primary heat source. By relying on combustible fuels for heating, multi-fuel cupellation furnace significantly cuts laboratory power infrastructure costs, requiring only a standard 220V/50Hz electricity supply to power its internal control systems and pneumatic door mechanisms.

Whether processing samples in a remote mining facility with an unstable power grid or a high-throughput commercial testing laboratory, each multi-fuel cupellation furnace provides a reliable, standardized thermal environment.

Target Applications & Samples: Ideal for precious metal determination, gold/silver cupellation processes, and specialized fire assay workflows.
Processing Capacity Options: Available in 3 standard throughput specifications, supporting 50-position, 100-position, or 168-position batches to align with your daily laboratory output.

Application Scenarios

Precious metal mines and on-site exploration teams, especially in remote areas with limited grid power access
Precious metal smelting and refining enterprises for batch sample processing and production quality control
Geological and mineral exploration laboratories for rock, ore, and concentrate sample preparation
Third-party analytical testing institutions for high-throughput precious metal content analysis
Small-scale artisanal and industrial mining operations with unstable power grid infrastructure
Environmental testing laboratories for heavy metal analysis in mining waste and tailings samples
