Press Release Summary:
Available in process lengths up to 305 mm, Horizontal Tube Furnaces will accommodate tubes up to 76 mm OD. Benchtop units are suitable for applications in which sample or product is relatively small and must be processed in inert, reducing, or oxygen atmospheres. Tube preserves integrity of sample and furnace interior, preventing chemical reactions which might contaminate sample, damage furnace heating elements or insulation, or reduce maximum furnace operating temperature.
Original Press Release:
Deltech, Inc. is Pleased to Introduce Our New Horizontal Tube Design
Deltech, Inc. is pleased to introduce our new horizontal tube design. Our newest horizontal tube furnaces are true “benchtop” units. They are lighter in weight and more compact, requiring a smaller footprint. A top plug provides convenient access to the furnace interior.
Horizontal tube furnaces are useful for applications in which a sample or product is relatively small and must be processed in inert, reducing, or oxygen atmospheres. The material is placed in a combustion boat (most often platinum or ceramic) and slid into place in a process tube. Process tubes are most often alumina (for use at up to 1800 degrees centigrade), mullite (1600 degrees centigrade), or quartz (1200 degrees centigrade).
The tube preserves the integrity of the sample and the furnace interior, preventing chemical reactions which might contaminate the sample, damage the furnace heating elements or insulation, or greatly reduce the maximum furnace operating temperature. For example, reducing atmospheres attack the molydisilicide heating elements which are used for furnace operating temperatures of 1600 deg C to 1800 deg C. Thus prolonging element life in dry hydrogen requires limiting the furnace temperature to 1150 deg C. Use of a tube furnace eliminates this problem.
Gases can be introduced by using end caps to seal the tube and a gas delivery system to control the gas mixtures and flow rates.
Deltech’s new horizontal tube furnaces are available in process lengths up to 305mm and will accommodate tubes up to 76mm O.D. They can be supplied alone or with a Deltech UL508A listed (by Intertek) control system designed for the particular unit being purchased, gas mixing systems, process tubes, and water cooled end caps that provide access to the tube interior without the need to remove the seal.
