Laboratory Furnace Applications and Selections

From sintering to annealing and debinding to calcining, furnaces play a vital role in laboratories. As all applications are different, you will need to alter furnace configurations and temperature ranges to ensure accurate results. Some applications may even require inert gas, so a furnace that is compatible with gases is necessary.

MSE Supplies offers various types of furnaces, such as muffle furnaces, tube furnaces and chamber furnaces. Learn more about the types of lab furnaces and various lab furnace applications.

What Is a Laboratory Furnace?

A laboratory furnace enables technicians to heat samples over an extended period. They are typically constructed from durable ceramics, ensuring they remain intact, even under high temperatures. When choosing a furnace for your application, you can assess specifications such as the height, width and length of the tube or chamber. You'll also need to consider whether the maximum temperature range meets your needs.

Muffle Furnace

A muffle furnace has a ceramic muffle, which laboratory technicians heat via conduction, convection or blackbody radiation from heating elements. This type of furnace generally comes in the form of a box-type oven or kiln, allowing for high temperature applications of up to 1100 degrees Celsius.

Muffle furnaces provide a cost and energy-efficient equipment option for the biomedical, textile and pharmaceutical industries, among others. One of the most common applications of a muffle furnace is to determine the proportion of non-combustible and non-volatile material in a sample. By isolating materials, scientists limit cross-contamination and identify specific components for analysis. Some other standard lab furnace applications include:

• Fusing glass
• Manufacturing enamel coatings
• Creating ceramics
• Soldering metals 
• Brazing two or more pieces of metal

In the chart below, you can compare some of the muffle furnace options we provide.

Tube furnace 

Tube furnaces consist of a ceramic tube surrounded by heating elements for optimal temperature distribution. Due to its precise temperature control, a laboratory tube furnace enables applications such as: 

• Thermocouple calibration
• Crystal growth
• Fuel cells testing
• Catalyst processes

One of the main applications for this piece of equipment is to conduct syntheses and purifications of inorganic compounds. Laboratories also occasionally use tube furnaces in organic synthesis. In addition, technicians rely on tube furnaces for uses such as coating, drying, hardening, annealing, degassing and sintering.

At MSE Supplies, we offer different types of tube furnaces, including split, rotary, horizontal and vertical. Here are a few examples:

Chamber Furnaces

Chamber furnaces consist of refractory bricks for maximum insulation. By pairing your chamber furnace with an annealing box, you extend the application range to include:

• Operation under protective gas
• Roller guide processes 
• A cooling station with a quench tank
