Tube Furnace
The Lab Tube Furnace is an electric device used for synthesizing and purifying inorganic and organic compounds. It has a cylindrical cavity surrounded by heating coils in a thermally insulating matrix.
Temperature is monitored and regulated with a thermocouple and digital controller. Some models have multiple heating zones and an RS-232 interface for programming specific functions.
With heating elements made of materials like MoSi2, these furnaces can work up to 1800 °C, allowing for advanced applications. Tube materials vary based on reactant corrosiveness and can include alumina, Pyrex, fused quartz, molybdenum, or tungsten.
We have the best tube furnace solutions for all your laboratory needs. Our extensive portfolio offers a range of standard solutions to meet your requirements. Whether you need a single or multi-zone, horizontal/vertical, split & rotating model, or continuous/batch rotary tube furnace, we have got you covered. Our bespoke design service allows us to meet almost any customer requirement.
Using a tube furnace instead of a chamber furnace offers several advantages, such as being more appropriate for handling smaller samples due to its smaller volume capacity and faster heat-up rates. Work tubes that are sealed provide protection to the furnace's construction from contaminants, while also simplifying the maintenance of a modified atmosphere around the samples.

FAQ
What is a tube furnace?
Laboratory tube furnace is one classic external heating high temperature tube furnace, also named hot wall heating furnace.
According to the different working temperature, furnace tube material usually can be transparent quartz tubes, high purity alumina ceramic tubes and high strength metal alloy tubes.
To meet different thermal researching purposes, tube furnace can be designed with multi heating zones, so as to have a flexible control of temperature gradient in the tube working chamber; furnace tube can work with a controlled atmosphere working environment or a high vacuum working environment.
How does a tube furnace work?
Tube furnace heating elements are placed surrounding the cylindrical cavity, furnace can only heat the samples in the cylindrical cavity through indirect thermal radiation, since furnace tube can prevent sample material from contacting with furnace heating elements and insulation materials, so tube furnace creates a clean isolated heat chamber and reduce risks of the sample material contaminating by the furnace.
What is the application for tube furnace?
Tubular furnace is mainly used in metallurgy, glass, heat treatment, lithium anode and cathode materials, new energy, abrasives and other industries, and is a professional equipment for measuring materials under certain temperature conditions.
Tube furnace features simple structure, easy operation, easy control and continuous production.
Tube furnace is also widely applied in the CVD (chemical vapor deposition) and plasma enhanced CVD systems.
How many different types tube furnace?
Tube furnace can work with different mechanical functions smoothly, so there are many different types tube furnace variations for different experiment purposes, typical furnace furnaces are as below:
Horizontal tube furnace
Vertical tube furnace
Split tube furnace
Rotary tube furnace
Tilting tube furnace
Sliding tube furnace
Fast heating and cooling tube furnace
Continuous feeding and discharging tube furnace
What are the advantages of using a tube furnace?
Tube furnaces offer several advantages for high-temperature applications. Firstly, they provide precise and uniform temperature control, allowing for accurate and repeatable heating processes. This is crucial for materials research and heat treatment applications where temperature consistency is essential. Secondly, tube furnaces have a compact design, making them suitable for use in limited laboratory or industrial spaces. They are also versatile and can accommodate a wide range of sample sizes and shapes. Additionally, tube furnaces are energy-efficient, as they typically have good insulation and can reach high temperatures quickly. Some models also offer programmable temperature profiles, allowing for automated heating and cooling cycles. Overall, tube furnaces enable efficient and controlled high-temperature processes in various scientific and industrial fields.
What safety precautions should be taken when using a tube furnace?
When using a tube furnace, it is important to follow safety precautions to prevent accidents and ensure operator and sample safety. Firstly, proper training should be provided to personnel operating the furnace to ensure they understand its operation, safety features, and emergency procedures. Secondly, appropriate personal protective equipment (PPE), such as heat-resistant gloves, goggles, and lab coats, should be worn to protect against burns and potential hazards. Thirdly, it is crucial to properly load the sample or material inside the furnace, ensuring it is securely positioned and does not obstruct airflow. Adequate ventilation should be provided to remove any potential gases or fumes generated during heating. It is also important to regularly inspect and maintain the furnace, including checking the heating elements and electrical connections, to ensure safe and reliable operation.
