Tube Furnaces

Carbolite’s extensive range of Laboratory Tube Furnaces is one of the most comprehensive available from a single source. Our portfolio includes tube furnaces ranging from 900°C to 1800°C, both vertical and horizontal orientations, single and three zone configurations as well as solid and split-hinged designs. In addition to the traditional tube furnace design, we also manufacture Vacuum Tube Furnaces, Rotating and Rotary Reactor Furnaces as well as a furnace designed specifically for the calibration of thermocouples.

Carbolite tube furnaces offer precise temperature control, excellent temperature uniformity and then best solution for heating small work pieces. Many of our tube furnace models combine an integral control system, but are also available with separate control systems suitable for vertical use.

Carbolite 900°C, 1000°C, 1200°C Wire-Wound Tube Furnaces

900°C, 1000°C & 1200°C 1 & 3 Zone Wire-Wound Tube Furnaces

Carbolite’s 1 and 3 zone, Wire Wound Tube Furnaces utilize resistive wire heating elements, which is wound around the outside of a ceramic worktube making it an integral part of the tube furnace's heating element. If your process requires the addition of an atmosphere or is likely to be contaminated by spillage, an additional worktube should be used. The thermocouple is located in a protected position outside of the worktube and the heating element, allowing the full worktube diameter to be used and protects the thermocouple from mechanical damage. These tube furnaces are available in a variety of heated lengths ranging from 5" (130mm) to 35.5" (900mm) and with tube diameters ranging from 0.6" (15mm) to 4.0" (100mm).

Carbolite 1200°C Vertical, Split-Hinge Tube Furnace

1200°C 1 & 3 Zone Split-Hinge Tube Furnaces

Carbolite’s Split-Hinge tube furnaces are manufactured in two halves and are hinged together to permit easy loading of a worktube reactor vessel or large work piece. The design affords one the flexibility to place the tube furnace around a fixed item, such as a pipe with flanges which would not pass through a solid tube furnace. These furnaces are available in either a horizontal or vertical orientation and have a maximum temperature of 1200°C. The product line includes both single and three zone designs, and is available in a variety of heated lengths ranging from 8" (200mm) to 35.5" (900mm). These tube furnaces are capable of accepting a tube with a maximum OD of up to 4" (110mm).

1200°C 1 & 3 Zone Vertical Split-Hinge Tube Furnaces

Carbolite 1200°C Large Bore Tube Furnace

1200°C 1 & 3 Zone Large Bore Tube Furnaces

Carbolite’s G range tube furnaces can accept worktubes with an outside diameter up to 6.5" (170mm). The range of products includes six heated lengths from 17.75" (450mm) to 47.25" (1200mm); can be provided in either a horizontal or vertical tube orientations and designed with either a single-zone or three-zone control. An integral worktube is not fitted and a separate worktube must be used. Removable tube adaptors at each end of the furnace allow rapid changes for different size worktubes.

The horizontal tube furnace models are mounted on an attractive base unit and the vertical tube furnace models are supplied with a stand kit and a separate control box.

Carbolite 1500°C and 1600°C High Temperature Tube Furnace

1500°C & 1600°C 1 & 3 Zone High Temperature Tube Furnaces

Carbolite’s 1500°C and 1600°C tube furnaces utilize silicon carbide heating elements arranged in a heated chamber surrounding the worktube, and provide even heating of the tube surface for maximum temperature uniformity, these tube furnaces can be mounted for use either horizontally or vertically, with an optional stand. These tube furnaces are available in three different heated lengths, 7" (180mm), 17.75" (450mm), 24" (610mm).

Carbolite 1700°C and 1800°C High Temperature Horizontal Tube Furnace

1700°C & 1800°C 1 & 3 Zone Horizontal Tube Furnaces

Carbolite’s high temperature tube furnaces are available in both 1700°C and 1800°C designs. These furnaces use either a molybdenum disilicide heating element or lanthanum chromite element depending on the model. These tube furnaces are available as either a single-zone or three-zone configuration, accept a process tube of up to 3.5" (90mm) OD and are designed with heated lengths of 12" (300mm) and 23.75" (600mm).

Carbolite 1700°C and 1800°C High Temperature, Vertical Tube Furnace

1700°C and 1800°C Vertical Tube Furnaces
