Assay / Carat Control System
System is most trustable method for checking the purity of precious metals. With traditional method of assay control system working with cupellation process. Samples taking on goods weight checking and after cuppellation process sample weight checking again then differences given assay of samples.
System includes all needs:
- Polypropylene Hood and Working Chamber
- All Glass Equipments for Tests
- Cupellation Furnace
- Precision Weight Control System
- Spare and Wear Parts
- Process Know-How

Cupellation Furnace
Cupellation is a refining process to removing all non-precious metals to detect exactly precious metal, like gold and silver. The ores or alloyed metals are treated under very high temperatures and have controlled operations.
Our cupellation furnaces have several control mechanism and features for the increased life of furnace and resistance. Some of those, silicon carbide resistances (obtain for high power), stainless steel structure, insulated walls for keeping heat and block heat transfer to outside. Also, the electrical control panel is working to avoid personal mistakes and checking the temperature on each phase.
If some problems cause on the furnace such as heat transfer to inside the furnace, the cooling system will protect until cooldown.
There are several kinds of furnaces for small, medium or big capacity.
Portable XRF Analyzer
The XRF analyzer device can detect material quality very quick and provides spectrochemical analysis capability, testing of wide range of metal bars and other materials such as ash, catalytic converter, ore etc.
In metal fields, carat or assay control are very important to understand quality of materials.
