Jewelry and Gold Assay Houses (Precious Metals)

Sector Challenges

In Jewelry and Gold Assay Houses (Precious Metals), quality is defined by cupellation accuracy, lead fume extraction, high temperature stability, reduced sample loss, uniform heat distribution. Small deviations at these points can shift reported values and business decisions.

Field conditions increase risks such as lead fume exposure, thermal shock, metal loss. Compliance with international assay procedures and repeatable process control is therefore essential.

YekGlobal Technology and Solutions

YekGlobal systems support cupellation, sweep burning, ash combustion with stable temperature control, reliable airflow management, and consistent measurement infrastructure.

Stable temperature during cupellation reduces deviations in gold purity calculations. Integrated airflow in the fume hood prevents lead vapors from returning to the operator zone.

Critical Features

1600°C high-temperature durability
Sealed lid with safe insulation
High extraction performance with filtered exhaust
Programmable heating ramps
Easy maintenance and ceramic interior

We combine layout planning, validation support, and operator training to sustain performance over the full lifecycle.

Recommended products for this sector include: YEK-MF SERIES KÜL FIRINI, Kül Fırını 1600°C, Çeker Ocak.

Standardized sample preparation across cupellation, sweep burning, ash combustion reduces uncertainty and improves inter-lab comparability.

Uniformity mapping ensures each shelf experiences the same conditions, limiting drift between runs.

Data logging and traceable reporting support audits and align with international assay procedures expectations.

Multi-layer insulation and sealed doors improve energy efficiency and temperature stability.

High-extraction ventilation and chemical-resistant surfaces strengthen operator safety in routine workflows.

A defined calibration schedule protects measurement integrity under intensive use.
