FAQs for University Purchasing Three-Zone Tubular Furnaces

1. What is a three-zone tubular furnace?

A three-zone tubular furnace features three independently controlled zones on the same tube, enabling temperature gradient control or full temperature control. This makes it ideal for research applications such as material heat treatment and temperature differential experiments.

2. Can the three zones be controlled separately?

Yes. Each zone is equipped with an independent temperature control module, allowing for individual temperature settings to maximize temperature distribution.

3. What are the temperature ranges and control accuracy?

The selectable temperature ranges are 1100°C/1200°C/1400°C/1600°C/1700°C, with a control accuracy of ±1°C. Programmable temperature control (30 or more steps) is supported.

4. Can a temperature gradient be created?

Yes. By setting different temperatures in each zone, a temperature gradient can be created. This is widely used for research such as material migration and thermal diffusion.

5. What are the furnace tube specifications?

Conventional furnace tubes are available in sizes of 60, 80, and 100 mm, with customizable lengths. Materials include quartz, corundum, and silicon carbide.

6. Does it support protective atmosphere or vacuum?

Yes. The equipment is equipped with gas ports and sealing flanges for accepting protective gases such as nitrogen, argon, and hydrogen. A vacuum system is optional.

7. What are the research advantages of a three-zone furnace?

Larger effective heating area (center + ends)

Improved temperature uniformity

Can be used for hot zone transfer experiments and gradient material synthesis

Increased sample processing flexibility and accuracy

8. Delivery time and after-sales service?

Standard models ship within 7–15 business days. The entire unit comes with a one-year warranty, and user guidance, technical support, and remote debugging are provided.

9. What documents can be provided for laboratory records?

Provide factory inspection reports, certificates of conformity, manuals, and electrical drawings.
