Heating furnace N 4/13 CUP

meltingcupellationlaboratory

Cupellation is a process to separate precious metals, such as gold or silver, from alloys with base metals. During the process, aggressive gases that attack the insulation and the heating are released. Cupellation furnaces N ../13 CUP are especially designed for the very demanding process requirements. The furnace chamber consists of a ceramic muffle, which offers very good protection for the heating elements and insulation against the vapors. A special fresh-air and exhaust air system guides exhaust gases directly into the exhaust hood of the cupellation furnace. At the same time, fresh air is lead into the furnace atmosphere. The integrated exhaust hood on top of the furnace and above the door is the interface to the customer’s required exhaust air system. The design is very-maintenance friendly; all wear and tear parts on the furnace, which are f.i. the ceramic muffle and the heating elements, can be replaced easily. Cupellation furnaces N 4/13 CUP as a tabletop model and N 10/13 CUP are designed especially for cupellation. Due of its high chamber design, model N 30/13 CUP can also be used for crucible melting. Pit-type furnace S 73/HS is especially designed for crucible melting.
