SKU: N/A

These compact universal split 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.

The single zone EST and 3-zone EZS split tube furnaces comprise a furnace body which is hinged and split into two halves along its length. This makes exchange of work tubes easier and also enables the furnace to be used with reactors or work tubes where end flanges would make insertion into a non-split furnace difficult.

The 3-zone EZS furnaces provide excellent uniformity resulting from division of the heated length into 3 zones with its own controller and thermocouple. This range of tube furnaces does not include an integral work tube which 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.

(0)
SKU: N/A

With the adjustable stand option, the Carbolite Gero graphite tube furnace range up to 2600 °C can be used at various angles, ranging from horizontal to vertical.

This range of cold wall tube furnaces is heated by graphite elements and insulated by graphite felt. At higher temperatures above 400 to 600 °C graphite is air sensitive and needs to be kept under either an inert gas or vacuum atmosphere. To maintain an oxygen free environment, the tube furnace is contained within in a water-cooled vacuum tight vessel sealed with rubber O-rings, which needs to be evacuated and purged with inert gas prior to heating.

The thermal conductivity of graphite felt insulation is very low making it an excellent material for furnace insulation. The thickness and quality of the insulation materials are specifically chosen depending on the maximum operating temperature of the tube furnace.

(0)
SKU: N/A

The Carbolite Gero high temperature tube furnaces HTRH can be used horizontally up to 1800 °C. 

The high-grade insulation materials guarantee low energy consumption and high heating rates due to their low thermal conductivity. The insulation and molybdenum disilicide (MoSi2) heating elements are installed in the rectangular housing. The heating elements are vertically hanging and can be replaced easily. At higher temperatures and in the presence of oxygen, MoSi2develops an oxide (SiO2) layer, which protects the heating elements against further thermal or chemical corrosion.

Three-zone tube furnaces (HTRH-3) can achieve better temperature uniformity than single-zone versions. In these models each zone is equipped with a dedicated thermocouple and controller, which is especially useful to preheat gases required for reactions inside the system.

The HTRH tube furnaces do not include an integral work tube. The work tube must be selected as an additional item. The work tube length is dependent on the application and will vary if used with or without modified atmosphere or vacuum.

Carbolite Graphite Tube Furnace – HTRH-GR

0 out of 5
(0)

With the adjustable stand option, the Carbolite Gero graphite tube furnace range up to 2600 °C can be used at various angles, ranging from horizontal to vertical.

This range of cold wall tube furnaces is heated by graphite elements and insulated by graphite felt. At higher temperatures above 400 to 600 °C graphite is air sensitive and needs to be kept under either an inert gas or vacuum atmosphere. To maintain an oxygen free environment, the tube furnace is contained within in a water-cooled vacuum tight vessel sealed with rubber O-rings, which needs to be evacuated and purged with inert gas prior to heating.

The thermal conductivity of graphite felt insulation is very low making it an excellent material for furnace insulation. The thickness and quality of the insulation materials are specifically chosen depending on the maximum operating temperature of the tube furnace.
