Lab Furnace

Laboratory Furnaces are constructed to go to higher temperatures than traditional ovens. Ovens normally only go to 250° to 400° C. To achieve higher temperatures, manufacturers use ceramic fiber insulation and embedded heating elements on top and both sides. Whether for ashing, drying, firing of coatings or for heat treating ceramics and tiles, laboratory furnaces can be used for these applications.

Types of Laboratory Furnaces

Box / Muffle

Muffle furnaces are used when high temperatures are needed- such as ignition tests, gravimetric analysis, heat treating steel parts, and other applications.

Tube Furnaces

Tube furnaces are used in purifications and synthesis when rapid heating is required. Most often used in educational, industrial and governmental laboratories.

Crucible

Crucible Furnaces are simple melting furnaces. Usually used to safely melt precious metals.

Vacuum

Vacuum Furnaces are also called Vacuum Induction Melting Furnaces. They are generally used to make superalloys- stainless steel, magnetic/battery alloys, electronic alloys are some examples.
