Tube furnaces enable a closely controlled, heated environment to be created for small scale test-work. The work-tube may be oriented horizontally, vertically or be fully adjustable to any angle. Work-tubes range in size from less than 25mm to over 150mm diameter and may be made from a number of ceramic materials, depending on the requirements.

Maximum operating temperatures can be as low as 200°C or as high as 1800°C(3272°F).

For some test-work, tube furnaces have one, two, three or more heated and controlled zones.

For a controlled atmosphere within the worktube, tube-end caps and an atmosphere gas control system is added.

T°: from 200°C up to 1800°C
