Tube Furnaces

A tube furnace is a type of furnace used for heating materials in a tube-shaped chamber. It is commonly used in laboratory and industrial processes for thermal treatment, such as calcination, sintering, and annealing, where precise temperature control is required.

•  Intelligent System Controller with 7″ Color Touch Panel: Allows for easy control and programming of complex heating processes. Displays clear visual heating curves and can store temperature profiles.
• Vacuum-Formed Ceramic Fiber Chamber: Made from vacuum-formed ceramic fiber, enhancing both durability and heat retention.
• High-Quality Lining and Heating Elements: High-quality furnace linings and premium-grade heating elements to ensure reliable performance and longevity.
• Double-Layered Steel Casing with Fan Cooling: The double-layered steel casing, combined with fan cooling, provides improved thermal insulation and enhanced safety.
• Comprehensive Technical Support and Customization Options: Backed by extensive technical support and a wide range of customization options to meet the unique needs of your applications.

Our tube furnaces can reach up to 1200°C or 1500°C, we also offer high-temperature furnaces that go up to 1700°C.

Sure, our tube furnaces feature programmable controllers for multi-step heating, holding, and cooling processes via an intuitive and easy-to-operate touch screen, with the ability to pre-setting sintering curves.

The heating rate range can be from 1°C/hour to 20°C/min.

Our tube furnaces are designed for high temperature uniformity, with differences usually within ±5°C, and temperature control accuracy within ±1°C.

• Materials science for synthesizing and testing new materials.
• Ceramics for sintering and thermal treatments.
• Metallurgy for heat-treating metals.
• Nanotechnology for growing nanowires and nanotubes.
• Chemical processing for reactions at controlled temperatures.
• Semiconductors for doping silicon wafers.

• Air (standard conditions)
• Vacuum
• Inert gases such as argon or nitrogen
• Reducing(H2) or oxidizing gases

• Resistance (Mo-doped Fe-Cr-Al) wire: used for lower temperature applications(up to 1200°C).
• Molybdenum disilicide (MoSi2): used for high temperatures (up to 1800°C).
• Silicon carbide (SiC): also used for high temperatures (up to 1500°C).

Tube furnaces come in various sizes depending on the application, from small laboratory units with tube diameters around 25 mm to 100 mm to large industrial units with diameters exceeding 300 mm.

Split tube furnaces have a design that allows the furnace to open along the middle, making it easier to insert and remove the tube. This is particularly useful for experiments that require frequent loading and unloading of samples.

• Different heating zones for temperature gradients.
• Gas mixing systems for introducing different gases.
• Vacuum systems for processing under vacuum conditions.

• Over-temperature protection to prevent overheating.
• Gas flow monitoring systems for handling flammable or hazardous gases.
• Insulation to reduce heat loss and protect the user.

Temperature is controlled through intelligent controllers, offering precise temperature settings and automated ramping profiles.

ZYLAB tube furnaces use high-quality vacuum formed ceramic fiber insulation to minimize heat loss and improve energy efficiency.

Yes, all ZYLAB tube furnaces come with stainless steel flange, can be used under vacuum or inert gas(controlled atmosphere) environments.
