Accurate control of temperature gradient to meet complex experimental requirements
Multi temperature zone independent control: The multi temperature zone gradient tube furnace can achieve precise control of multiple different temperature zones inside the furnace tube. Each temperature zone can be independently set to meet the needs of different temperature environments in experiments. For example, in the preparation of composite materials, a low-temperature zone can be set up for raw material deposition, and a high-temperature zone can be set up for particle sintering. The reaction rate and product phase distribution can be controlled by temperature gradient to avoid the problem of uneven products at a single temperature.
Wide temperature range: This type of tube furnace usually has a wide temperature control range, which can be achieved from room temperature to high temperature (such as 1200 ℃, 1600 ℃ or even higher), and is suitable for various experimental needs.

Flexible design of experiments to enhance material performance
Simulating real processes: In the heat treatment process of metal and ceramic materials, multi temperature gradient tube furnaces can simulate real heat treatment processes such as quenching, annealing, and tempering. By controlling the residence time of samples in different temperature zones, it is possible to accurately simulate the heat treatment process in actual production and study the phase transition behavior and mechanical property changes of materials at different temperatures.
Optimizing material structure: When preparing gradient materials, such as thermal barrier coatings, a gradient from high temperature to low temperature can be set inside the furnace tube to continuously change the coating composition and structure along the thickness direction, thereby improving thermal shock resistance. Gradient structure can reduce thermal stress concentration and extend the service life of materials.

Efficient integration of processes, saving time and resources
Continuous processing: Some complex heat treatment processes, such as sintering, annealing, and deposition, require multi-step processing at different temperatures. The multi temperature gradient tube furnace can achieve these steps in a continuous process, avoiding the heat loss and pollution problems caused by sample transfer, and improving experimental efficiency.
Parallel experiment: In material screening experiments, a multi temperature gradient tube furnace can process multiple samples simultaneously, with each sample in a different temperature range. For example, in catalyst screening, the same furnace can test the activity at different temperatures, shorten the experimental period, and reduce experimental costs.

Uniform heating to ensure experimental accuracy
Uniform temperature distribution: By using good heating elements and furnace tube design, the multi temperature zone gradient tube furnace can ensure uniform temperature distribution inside the furnace tube, avoiding damage to the sample due to local overheating. This is important for the preparation of materials with high uniformity requirements, such as the preparation of thin film materials.
Chemical stability: Furnace tube materials (such as corundum tubes, quartz tubes, etc.) have good high temperature resistance and chemical stability, ensuring the safety and reliability of experiments.

Energy saving and safety, reducing operating costs
Energy saving design: Through temperature gradient design, the multi zone gradient tube furnace only heats up in areas that require high temperatures, reducing overall energy consumption and lowering operating costs. Meanwhile, its air cooling system and efficient insulation technology also help reduce heat loss and improve energy utilization efficiency.
Safety protection: Equipped with comprehensive safety protection devices such as overheating protection, overtemperature alarm, leakage protection, etc., to ensure that the equipment can be shut down in a timely manner and issue warnings in case of abnormal situations, ensuring the safety of operators and equipment.
