Muffle Laboratory Furnace

Hoskins Manufacturing invented the FD 204 Muffle Furnace in 1920 in Detroit, Michigan. Records show entrepreneurs such as Henry Ford, Thomas Edison, Fisher, Packard Motor, Cadillac, Dodge, Universities and Metallurgical Laboratories all using this innovative muffle furnace. The design is the standard by which all others are measured. In 1991 National Element, Inc. purchased the Hoskins furnace line.

Overview

  • Temperature controlled by precision microprocessor
  • Heating element easily accessible for do-it-yourself repair
  • Electric heat is efficient and clean
  • Fully pre-wired
  • Stainless Steel casing
  • Digital temperature setpoint and readout
  • Uses standard thermocouple

Maximum Temperatures:
FD - 1832° F
FH - 2000° F

FD Furnace only:
Sulfur ores should not to be treated in the Type FD furnace as the sulfur fumes penetrate the muffle walls and reduce the life of the heating elements. When working with salts (common salt, potassium cyanide, saltpeter, etc.) that fuse below the working temperature of the furnace, care should be taken not to spill any on the floor of the muffle. The fused salt penetrates the muffle wall and injures and/or contaminates the heating element. When working with such material, it is advisable to use a metal tray on the floor of the furnace.
