Three Zone Tube Furnace DTZF3/12
Three zone tube furnaces feature the famous Kanthal (Sweden) resistance wire as their heating elements. Furnace hearth is built with Mitsubishi (Japan) high quality fiber materials. Temperature of this furnace is controlled by high precision temperature controller (Shimaden fp93 from Japan) with +/-1 °C accuracy and 40 programmable segments. Furnace housing is built with double-layer steel and two cooling fans inside keep the furnace body temperature low. Furnace tube is sealed by stainless steel vacuum sealing flanges, it can be used under vacuum and other gases condition. This tube furnace is an ideal tool for sintering all types of materials/chemical. Great for labs or college scientific research use.
These furnaces have built-in interface to a computer. We provide connection cable, adaptor and software that can be used to control the temperature and parameters of the furnace, all from your PC. You can also save a temperature curve for record or study purposes.
All our furnaces are CE certified.
Safety features
1 Furnace overheat protection cuts off power when temperature is over the desired range.
2 Thermocouple protection cuts off power when the thermocouple is broken or malfunctioned.
3 Temperature variation protection cuts off power when the difference between actual temperature and target temperature is off the desired range. (Refer to controller’s manual)
4 Power failure protection resume furnace operation right after the point of failure when power is back up.
5 Stainless steel flange support makes sure the tube and flanges are secure and in their absolute position, it also longer the life of the tube.
Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.

Precise, Uniform High-Temperature Processing with the Three Zone Tube Furnace DTZF3/12
Achieve exceptional thermal uniformity and independent temperature control for advanced materials synthesis, sintering, calcination, and heat treatment with the Three Zone Tube Furnace DTZF3/12—a high-performance laboratory furnace engineered for research labs, universities, and industrial R&D. Featuring three independently controlled heating zones within a single 1200°C (2192°F) rated chamber, the DTZF3/12 enables precise thermal profiling for nanomaterials, ceramics, catalysts, and semiconductor processing.
Engineered for Gradient Control, Stability, and Reproducibility
The DTZF3/12 Three Zone Tube Furnace integrates three separate PID-controlled heating sections—each programmable up to 1200°C—allowing users to create customized temperature gradients (e.g., hot center with cooler ends) or maintain a single uniform zone with minimized edge effects. The high-purity alumina or quartz tube (Ø 50–100 mm, 1000 mm length) ensures chemical inertness, while the vacuum-tight flanges (with optional gas inlets/outlets) support inert, reducing, or reactive atmospheres (N₂, Ar, H₂, air).
- Three Independent Zones – Each with separate thermocouple and PID control for advanced thermal profiling.
- Max Temperature: 1200°C – Continuous operation up to 1100°C; ideal for oxides, metals, and ceramics.
- Excellent Uniformity: ±2°C over 300 mm hot zone – Critical for reproducible material synthesis.
- Vacuum & Gas-Compatible – Includes KF or CF flanges; supports vacuum to 10⁻² mbar or continuous gas flow.
- Digital Programmable Controller – 20-segment ramp/soak programming; data logging via USB/RS485 (optional).
- Robust Insulation & Safety – Energy-efficient ceramic fiber insulation; over-temperature protection and door interlock.
