Horizontal Tube Furnace Single Zone GHA Series

Horizontal Tube Furnace Single Zone GHA Series

Carbolite | Sample Preparation - Inorganic

The GHA tube furnaces use free radiating wire elements embedded within the insulation of the furnace body. The benefit of this design is its flexibility; with the use of tube adapters the same furnace can be used with a variety of tube diameters.

This range of tube furnaces does not include an integral work tube and one must be selected as an additional item. The work tube length is dependent on the application eg for use with modified atmosphere or vacuum. The use of a separate work tube has the advantage of protecting the heating elements from damage or contamination.

They can be either vertically or horizontally mounted with their 'Versatile' stand design.
