Description and Specifications of Tube Furnace

A Tube Furnace is an electric heater used to make and purify chemicals. It has a long cylinder shape with heating coils wrapped around it. The coils heat up when electricity goes through them. There is a thermocouple inside to check the temperature. The thermocouple sends signals to control the heat so the temperature stays where it wants. It is also known as Tubular Furnace.

It can have one heated section or several separate heated areas. This allows materials to be heated evenly all along the tube. Even heating and temperature control are helpful for many things involving heat. For example, it purifies or prepares chemicals by heating. It can also strengthen materials through heating by a process called annealing. Other uses are coating wires, drying coatings or films, and testing how materials age when heated.

The cylinder cavity holds small samples for treatment. Tube furnace often use inert gases like argon or nitrogen inside. This protects reactive materials from unwanted reactions with oxygen during heating. The inert atmosphere gives more control over the chemical process.

Design and Structure

Different designs suit different needs. Horizontal Tubular Furnace lay sideways, whereas vertical ones stand upright. Split furnaces open like a clam shell to access the tube. Rotary furnaces slowly rotate the tube while heating. Common tube materials are fused quartz, Pyrex, and ceramics that withstand high heat. Furnace tubes may also be metal like tungsten or molybdenum for heating corrosive stuff.

Temperatures can reach up to 1800 °C. Precise control and uniform heating make it ideal for research and production. Fields using it include chemistry, pharmaceuticals, electronics, metallurgy, and more.


  • Tube Furnace has a fully programmable control system to help with custom heating and cooling cycles, complex temperature steps, and hold times.
  • High-quality components like durable heating elements and reliable controllers minimize downtime and maximize productivity.
  • The low-maintenance design of the furnace minimizes downtime and simplifies operation for increased productivity.
  • The furnace has advanced safety features, over-temperature protection, and gas purging for safe and reliable operation.
  • The Uniform Temperature Control system and the advanced zone control ensure consistent uniform temperature throughout the tube.
  • The tube has extra sturdy construction for long-term durability and dependable performance.
  • The multi-zone control manages temperature gradients within the tube for complex experiments exactly.
  • The rapid ramp rate of the furnace helps achieve desired temperatures quickly and efficiently. This also boosts the throughput.
  • The furnace has a programmable cooling feature for customized cooling profiles that helps in optimal material properties.
  • The high-resolution thermocouples provide detailed and reliable temperature data for real-time monitoring.

Applications of Tube Furnace

A tube furnace is used in many areas because of its many uses. It helps to make and test new materials in science labs by baking, strengthening, and growing thin films on materials. It also helps to produce advanced things like nanomaterials, graphene, and tiny carbon tubes. It is essential to purify or make chemicals in chemistry and pharmaceutical research. It is also used in electronics to coat wires and make silicon wafers for computer chips. It helps in processing powders used to manufacture ceramic parts. Tubular Furnace helps treat metals to improve their strength and corrosion resistance. It plays a vital role in studying catalysts and doing analytics in many industries. The furnaces can heat evenly and keep the right temperature. This control lets it work for many processes that need heating. So, a tube furnace has various uses in science, industry, electronics, etc.

How to use Tube Furnace?

  • Choose the appropriate tube material and size for the application.
  • Securely mount the tube within the furnace chamber.
  • Set the desired temperature profile using the control panel.
  • Connect appropriate gas lines if using controlled atmospheres.
  • Initiate the heating process and monitor progress through real-time data.
  • Depending on the experiment, apply a vacuum or controlled atmosphere if required.
  • Allow the furnace to cool down gradually once the heating process is complete.
  • Carefully remove the sample from the furnace.

Clean the furnace to ensure proper maintenance and future use.

Safety guidelines

  • Wear protective gear, including heat-resistant gloves, goggles, lab coats, and closed-toe shoes when using a tube furnace.
  • Read and understand the instruction manual and adhere to all manufacturer safety guidelines for the specific furnace model.
  • Ensure only adequately trained personnel use the furnace following established safety protocols.
  • Operate these furnaces only in well-ventilated areas to remove hazardous fumes.
  • Avoid materials that release moisture or gases when heated in the furnaces.

Thoroughly clean the furnace before each use to remove any residue.
