Assay Furnace N 110/HS and S 73/HS

N 110/HS with manual lift door and integrated control cabinet

Customized pit-type furnace S 73/HS, with rolling lid for bigger charges in crucibles

Work platform in front of muffle to
place load

Furnace chamber of S 73/HS with SiC-plates as muffle function

N 110/HS

The N 110/HS furnace is especially used for the assay of precious metals where the insulation and heating must be protected from emerging gasses and vapours. The furnace chamber forms a ceramic muffle which can easily be replaced. In the standard design, the muffle is closed with a firebrick plug. A lift door can be installed instead upon request.

Tmax 1300 °C
Muffle heated from four sides
Heating elements and insulation protected by ceramic muffle
Simple replacement of muffle
Manual lift door
