Laboratory Furnace for High Temperature Applications

Laboratory furnaces offer constant conditions for processing materials and samples. They are usually built from refractory materials to sustain high temperatures without breaking down. Laboratories are often set up to function for months at a time to finish processing.

Key considerations for laboratory furnaces are general specifications, tube furnace features, control, and atmosphere. Laboratory furnaces that are used in high temperature applications must be made from materials that can withstand high levels of heat and not lose too much into the surrounding atmosphere.

Types of Laboratory Furnace

There are several choices of laboratory furnace configuration such as:

Bottom Load Furnaces

Bottom Load Furnaces

The laboratory furnaces are sometimes known as elevator furnaces. They can be bought in benchtop and production sizes and are used for operating temperatures of up to 1800°C. In a bottom load furnace, the body remains stationary and the load platform/kiln car is elevated into position.

Front Loading Furnace

Laboratory Furnace Front Load


Front loading furnaces are a type of laboratory furnace that is suitable for use with temperatures from 1500-1800°C. They come in benchtop and production sizes and are suitable for operation in air and inert atmospheres.

Glass Melt Laboratory Furnace

Laboratory Furnace


Not all laboratory furnaces are suited to glass melting. Glasses often have corrosive compositions and these fumes and splatter can harm furnace linings and heating elements. Glass melting laboratory furnaces need to be able to perform under the most demanding conditions and must withstand temperatures of as much as 1800°C.

Horizontal Tube Furnaces

Horizontal Tube Furnaces


Horizontal tube furnaces are well suited to applications that require processing under vacuum or in inert atmospheres but also have a relatively small diameter. The sample is put in a combustion boat and slides into the tube from one end. They are suitable for high temperature applications of up to 1800°C.


Metal Annealing Furnaces

Metal Annealing Furnace


These laboratory furnaces are suitable for isothermally annealing thin metal items that have a large footprint. These furnaces can be batch or continuous and are suitable for a range of applications.


Rocking/Oscillating Motion Ovens and Furnaces


Rocking/Oscillating Motion Ovens and Furnaces


These laboratory furnaces create agitation in melts before crystal growth. They are often used to incinerate waste and remove combustible elements, operating at temperatures of around 1000°C.
