Cupellation furnace - BRF12-CF24

Cupellation Furnace - BRF12-17-CF

1200°C

Overview

BRF12-17-CF Cupellation furnaces are specifically designed for the fire assay process, a standard method used to determine the purity of precious metals.

The design of the cupellation furnace range safeguards it from corrosive environments that could cause a conventional furnace to deteriorate.

This Cupellation furnace accommodates 24 cupels of size No.8 or 32 cupels of size No.6. We also offer a bigger chamber furnace that can hold 47 cupels of size no.8 or 70 cupels of size no.6.

We also provide cupellation furnaces with other capacities upon request.

Cupellation Furnace
  • Maximum Temperature: 1200°C
  • Maximum Continuous Temperature: 1200°C
  • Internal Chamber Dimensions (mm) (H × W × D): 200 × 250 × 340 (Bigger chamber furnaces are also available and can be offered upon request)
  • Combination of dense refractory for durability, load-bearing capacity, and corrosion resistance, with low thermal mass remainder for economical running.
  • The working chamber is lined with silicon carbide slabs to withstand the lead fumes evolved during the process.
  • A variable airflow system allows preheated air into the chamber and out through a large insulated chimney to evacuate process fumes as quickly as possible.
  • R-type Thermocouples
  • Over-temperature protection is fitted as standard.
  • A removable container attached to the chimney collects condensed lead.
  • A vertically lifting door keeps the hot surface away from the user.
  • A positive-break door safety switch isolates the heating elements from the power supply when the door is opened.
  • High-end microprocessor PID controller.
  • Multi segment, multi program storage controllers
  • An electrically operated door
  • 24-hour, 7-day timer for scheduled furnace operation throughout the week
  • Magnesia refractory cupels of various standard sizes

Note: Cupellation furnaces with other capacities are also available on request
