Mastering the standardized operation of the gas atmosphere control and valve operation of the three zone high temperature tube furnace is very important to ensure the safety of the equipment and the reliability of the experiment. In this article, I will combine the characteristics of the equipment to introduce you to the main precautions.

Working principle of dual heating zone tube furnace is not simple power-on heating, but through the coordination of heating system, temperature control system, atmosphere control system and structural adaptation design, the whole process management from temperature control to environmental protection is realized, and it provides a reliable high temperature environment for experiments and production.

The use of tube furnace is not limited to a single high-temperature heating, but revolves around material preparation, modification, and testing under precise temperature control, covering the whole process from laboratory small-batch research and development to industrial pilot testing, and providing stable and reliable heating environment support for technological breakthroughs in different fields.

The maximum operating temperature of open type vacuum tube furnace is 1200℃, and the maximum constant temperature gradient of the two temperature zones is 200℃. With high-purity quartz tubes and flanges, it can not only meet the temperature accuracy requirements of fine experiments, but also adapt to different batch sample processing scenarios. The application of open type vacuum tube furnace has deeply covered many fields such as new energy, semiconductor, ceramics, and scientific research in universities.

​For B-end buyers in the fields of material research and development and semiconductor manufacturing, mastering the standardized operation of small vacuum tube furnace can ensure experimental safety, data repeatability and equipment life.

Dual heating zone split tube furnace divides the heating tube body into two independent heating areas, each area is equipped with a dedicated heating element and temperature control system, which realizes the precise operation of one zone and one control.

1. Before using the tube furnace, install the insulation plugs. Position the insulation plugs as shown in the diagram. Pull them outwards as needed, but ensure they are symmetrical on both sides to prevent damage to the furnace chamber.

Small tube furnace is a kind of high-temperature experimental equipment with CE verification. It adopts a quick-connecting vacuum flange structure and a high-performance sealing ring, which allows one or both ends of the furnace tube to be quickly opened and closed, which facilitates the frequent picking and placing of samples and improves the experimental efficiency. The characteristic of small tube furnace is that it can work at temperatures up to 1200°C or in a vacuum environment. The furnace tube of small tube furnace can be configured as a 1-inch or 2-inch high-purity quartz furnace tube. The temperature control system of small tube furnace includes 30 heating and cooling curve settings, and its temperature control accuracy reaches +/-1°C. Small tube furnace is mainly used in scenarios that require high temperature and strict atmosphere, especially for the synthesis of materials in the laboratory, heat treatment, sintering and modification of battery materials, and catalyst research. High-temperature processes that require high efficiency and easy operation.

Single temperature zone tube furnace is a horizontally placed high temperature resistant furnace tube, and the material is placed in a heat-resistant container in the tube. In order to form a high temperature environment, there is usually a silicon-carbon rod heating element outside the furnace tube, so that the single temperature zone tube furnace can generate the heat required for the experiment. Single temperature zone tube furnace is managed by a temperature control system, which has a simple structure, easy operation and low cost.

Horizontal tube furnace is a CE-certified small experimental equipment with multiple heating zones, with a maximum temperature of 1100°C. Standard configuration includes stainless steel sealing flange and quartz tube. The horizontal tube furnace can be used immediately after it is powered on. Horizontal tube furnace is equipped with a 50-stage programmable temperature controller, which can set the heating and cooling procedures according to different customer needs. The horizontal tube furnace body can be placed vertically or horizontally to meet different applications, such as VSL, CVD, and other quenching tests.

Compact split tube furnace is an experimental equipment that has passed CE certification and is widely used in universities, scientific research, medicine and other fields. The maximum temperature of the compact split tube furnace can reach 1200°C. The instrument is equipped with precision vacuum test instruments, vacuum pumps and OMEGA temperature measuring instruments. Armored thermocouples can be extended into the furnace tube to measure the actual temperature of the sintered sample. The heating tube of the compact split tube furnace can be sealed at both ends, or it can be connected to a gas pipe to facilitate the passage of inert gas or reactive gas. This design makes compact split tube furnace popular with customers in experimental scenarios where the atmosphere needs to be controlled. The muffle furnace is also a common high-temperature heating equipment, but the muffle furnace is a closed box with a heating chamber inside, and the sample can be directly placed in the chamber for heating.
