OTF-1200X-IV Four-Zone Split Tube Furnace with 47″ Heating Zone and Optional Quartz Tubes up to 1200°C
The OTF-1200X-IV is engineered to support advanced thermal processing tasks such as annealing, diffusion, and sintering of samples in various controlled gas atmospheres. Its design addresses the need for a large uniform temperature zone, enabling consistent heat treatment over extended sample lengths.
This tube furnace features a total heating zone length of 1200 mm (47 inches), divided into four independently controlled zones of 300 mm each. This configuration allows the creation of a uniform temperature zone up to 36 inches long within ±5°C, ensuring precise thermal uniformity for sensitive processes.
Wichtigste Merkmale
- Four-zone split tube design with pneumatic cylinders for easy top cover operation.
- Optional quartz tubes with inner diameters of 8″, 10″, or 14.5″ and lengths up to 73″ for accommodating various sample sizes.
- Includes stainless steel 304 vacuum flanges with double high-temperature silicone O-rings and water cooling jackets for vacuum sealing.
- Equipped with three programmable digital temperature controllers using K-type thermocouples, providing ±1°C accuracy.
- Maximum heating temperature of 1200°C with continuous operation up to 1100°C; suitable for vacuum operation below 1000°C.
- PID automatic control with 30 programmable segments for precise heating/cooling rates and dwell times.
- RS485 communication port and software included for remote operation and monitoring.
