Joule Heat Tube Furnace

Joule Heat Tube Furnace

The Joule Heat Tube Furnace is a second-level heating device with adjustable temperature rise. The transparent quartz cavity allows visual observation of the sample status. It can process various samples in multiple environments such as atmosphere, vacuum, and normal pressure. The samples to be processed include powdery, block, and sheet forms, enabling rapid heating reactions and synthesis. It is widely applied in various fields such as material science preparation, catalyst synthesis, high-temperature material preparation and synthesis, and energy storage material experiments in research institutes and laboratories. The device is equipped with manual current adjustment, multi-stage temperature rise, and long-term heat preservation functions. It can maintain heat preservation for 30 minutes at 500–1600℃ and 60 seconds at 1600–2400℃ (specifically determined by the sample and sample stage). The device features adjustable sample stage spacing for easy installation, precise temperature control, and high sample sintering efficiency and repeatability.

Product Advantage:

1．Smart IoT Control: Supports remote monitoring and operation of equipment status via mobile phones and computers, ensuring convenience and efficiency;

2．Wide-Range Rapid Temperature Control: Temperature control range is 500–2400℃, with second-level heating for speed and reliability; it can maintain stable heat preservation for 30 minutes in the low-temperature range (500–1600℃) and 60 seconds in the high-temperature range (1600–2400℃);

3．Compact & Space-Saving: The miniaturized design of the equipment greatly saves space in laboratories or production sites;

4．Strong Adaptability: Powered by standard 220V, it is compatible with 4 types of sample stages (graphite paper, graphene paper, graphite tube, and graphite plate), meeting the testing needs of various sample forms;

5．Easy Sample Loading: Adjustable sample spacing and simple filling operation significantly reduce sample loading time;

6．Flexible & Controllable Environment: Supports quick switching between high vacuum (-0.1MPa), inert gas and atmospheric pressure environments, effectively avoiding sample oxidation and contamination;

7．Safe & Rapid Cooling: The fully enclosed design isolates personnel from high-temperature environments. The built-in heat dissipation fins + fan air-cooling system enables cooling from high temperature to safe temperature within 10 minutes, significantly shortening the test cycle;

8．Precise & Energy-Efficient Temperature Control: A reflective cover is added to form a thermal radiation closed loop. On one hand, it improves power utilization efficiency and reduces energy costs; on the other hand, it ensures uniform sample heating, compressing the temperature difference from ±3℃-±5℃ to within ±1℃. Combined with the equipment's temperature control logic, it achieves full-range precise temperature control.
