Multi temperature zone tube furnace for university experiments – atmosphere heat treatment furnace

1. Product Introduction
Multi temperature zone tube furnace for university experiments is a commonly used high-precision high-temperature heat treatment equipment in laboratories, research institutes, and material research and development centers of major universities. It is also commonly referred to as segmented temperature controlled tube furnace or gradient heating atmosphere furnace. This device breaks the limitations of traditional single temperature zone heating and adopts a multi group independent heating zone design, which can achieve segmented temperature control. It is equipped with a closed tube furnace and a multi-channel gas supply system, and can complete various material experiments in different environments such as vacuum, inert atmosphere, and reducing atmosphere. It is a commonly used basic experimental equipment in teaching and research projects in materials science, chemical engineering, new energy, semiconductor, inorganic non-metallic and other majors.

2. Core structure composition of equipment
Multi zone independent heating main body
The whole machine adopts a horizontal integrated structure, divided into multiple temperature zones such as dual temperature zone, triple temperature zone, and quadruple temperature zone. Each temperature zone is equipped with independent heating components and temperature measurement modules, which do not interfere with each other. The furnace is made of high-temperature resistant lightweight insulation materials, which have good insulation effect, fast heating, strong heat storage, and the shell does not overheat at low temperatures, making laboratory use safer.
Precision temperature control system
Equipped with intelligent PID digital temperature control instrument, it supports multi-stage program heating, constant temperature, and cooling curve settings, with high temperature control accuracy and real-time visual display of temperature values. The heating rate can be freely adjusted to meet diverse experimental processes such as slow heating, gradient insulation, and uniform cooling. The experimental data is stable and highly reproducible, making it suitable for writing papers and conducting research projects.
Closed tube furnace structure
Standard configuration includes high-purity quartz furnace tubes, corundum furnace tubes, and other optional furnace tubes, with good sealing performance. Both ends are designed with flange seals, ensuring no air leakage or pressure relief. It can both place experimental samples and isolate external air, creating a clean high-temperature reaction environment for the samples.
Vacuum and Atmosphere Supply System
The equipment can be equipped with a vacuum unit to achieve a low vacuum to high vacuum environment. It is also equipped with multiple precision gas flow meters, which can introduce various experimental gases such as nitrogen, argon, hydrogen, etc., and freely switch the atmosphere environment to meet different experimental conditions such as oxidation, reduction, and air isolation.
Multiple safety protection devices
Built in safety functions such as automatic power-off protection for overheating, thermocouple disconnection protection, overload protection, etc. During the experiment, if there are temperature abnormalities or temperature measurement failures, the machine can automatically shut down and issue warnings, effectively avoiding laboratory safety hazards and adapting to campus laboratory standards.

3. Main advantages of multi temperature zone tube furnace in universities
Segmented temperature control to create a gradient temperature field
The advantage of this equipment is independent temperature control in multiple temperature zones. Researchers can set different temperatures for different temperature zones according to experimental needs, easily simulate temperature gradient environments, and complete experimental projects that cannot be achieved by a single temperature zone furnace, such as long sample heat treatment, material gradient sintering, and slow phase transformation experiments.
Widely applicable experimental categories
One device can accommodate multiple heat treatment processes such as sintering, annealing, calcination, carbonization, gas-phase reaction, sample purification, and material drying. It is versatile and effectively saves laboratory equipment procurement costs, optimizing laboratory equipment configuration.
Uniform temperature and accurate experimental data
The combination of multiple temperature zones extends the constant temperature heating zone, and the temperature field inside the furnace tube is evenly distributed. Multiple sets of samples are placed and heated uniformly, with small experimental errors. The experimental results obtained are accurate and reliable, in line with the data standards for scientific research experiments in universities.
Easy to operate and user-friendly teaching
The device operation interface is simple and intuitive, and the program settings are easy to understand. Both teachers and students can quickly and proficiently operate it, which is suitable for professional scientific research in-depth experiments, as well as classroom teaching demonstrations and student practical training.
Energy saving and environmentally friendly, with low operating noise
Adopting energy-saving insulation structure, with less heat loss and lower energy consumption, the whole machine runs smoothly with low noise, suitable for quiet office and experimental environments in laboratories, and has high cost-effectiveness for long-term use.

4. Common technical configuration range
The standard maximum operating temperature is divided into multiple levels such as 1200 ℃, 1400 ℃, 1600 ℃, etc., to meet the high-temperature experiments of different materials; The temperature control accuracy can reach ± 1 ℃, and the heating rate can be controlled and adjusted; Support customization of furnace tubes with different diameters and lengths, and can accommodate experimental samples of varying sizes and specifications; The number of temperature zones can be flexibly customized according to the experimental site and experimental requirements.
