OTF-1500X-8Z 1500°C Eight-Zone Split Tube Furnace with Independent Temperature Control for Thermal Gradient Processing
The OTF-1500X-8Z tube furnace is engineered to support complex thermal gradient experiments essential in material science research. It enables controlled heating across eight distinct zones, allowing researchers to simulate and study temperature-dependent phenomena such as phase transitions and gradient functional materials synthesis. This capability is crucial for processes requiring precise spatial temperature variation within a single sample or along a material length.
The furnace incorporates a high-quality mullite ceramic tube with an outer diameter of 84 mm, inner diameter of 73 mm, and a length of 1219 mm, providing a robust and thermally stable environment. Each of the eight heating zones is equipped with silicon carbide heating elements controlled independently by dedicated PID temperature controllers, ensuring accurate temperature regulation with ±1°C precision. This design supports continuous operation at 1400°C and a maximum temperature of 1500°C, with a recommended heating rate of 5°C per minute.
Wichtigste Merkmale
- Eight independent heating zones, each 50 mm in length with 20 mm spacing, totaling 400 mm of heating length.
- PID automatic temperature control with 30 programmable segments per channel for precise heating and cooling profiles.
- Integrated S-type thermocouples for each zone providing accurate temperature feedback.
- Maximum temperature gradient capability of 100°C per inch, adjustable via thermal insulation spacers.
- Vacuum compatibility down to 10⁻⁵ torr using molecular pumps, suitable for low-pressure processing.
- RS485 communication port for laptop connection and real-time temperature profile monitoring.
- Includes two thermal blocks for optimized thermal distribution inside the tube.
