These assay furnaces have a unique long-life construction specifically designed for the assay of precious metals.

• Maximum operating temperature of 1200 °C
• Low airflow path directly over the cupels
• Positive break door safety switch

Silicon carbide heating elements are positioned above and below the work chamber, assuring excellent temperature uniformity. Heating elements are protected from spillage and corrosive fumes by silicon carbide tiles that form the roof and hearth of the furnace. Low thermal mass ceramic fiber insulation combined with high quality refractory brick provides maximum thermal efficiency. Insulated exhaust duct exits near the rear of chamber and incorporates a removable trap below the chimney to collect any condensed lead.
