Cupellation furnaces series TCF are used in the assay process of precious metals alloys. Cupellation is a procedure with the purpose to remove all non noble metal from the alloy to test.
Topcast TCF cupellation furnaces are provided with a built-in electromagnetic induction generator for the heating of the muffle. This leads to ultra fast work cycles and high energy efficiency.

An electronic control regulates the output power, and gives an advanced diagnostic system.

Main advantages of induction heating are:

  1. Fast heating: the muffle is directly heated by induction.
  2. Self-regulating: no more need to regulate power manually, with respect to furnace with silicon carbide resistance rods.
  3. Electrical energy consumption optimization: you don’t need to leave the furnace on to prevent thermal shocks to the resistor rods: when work is finished, the furnace may be turned off.


TOPCAST may also supply all tools and accessories for cupellation labs.
