Welcome to Acorn Scientific!
The tube furnace range GHA (single zone) / GHC (three zone) uses 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. The extended uniform zone in the mid-section of the work tube in the GHC 3-zone furnace is achieved with the use of end zone controllers which track the centre zone temperature and compensate for the loss of heat from the tube ends. 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, for example, 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.
