OTF-1200X-S-NT-LD Compact Split Tube Furnace with 1250°C Max Temperature, 8″ Heating Zone, and Programmable PID Controller
The OTF-1200X-S-NT-LD is engineered for laboratory applications requiring controlled high-temperature environments with flexible tube configurations. Its split tube design allows for convenient tube replacement and maintenance, accommodating 1″ or 2″ outer diameter processing tubes. This furnace is suitable for continuous operation up to 1250°C when used with a mullite tube, or up to 1100°C with a quartz tube, making it adaptable for various material processing needs.
Equipped with an 8-inch (200 mm) single heating zone, the furnace provides a stable temperature distribution, with a constant temperature zone of 2.3 inches (60 mm) maintaining ±1°C accuracy at 900°C. The built-in PID temperature controller supports up to 30 programmable heating and cooling segments, ensuring precise thermal profiles with automatic over-temperature and thermocouple failure protection. The maximum heating rate is controlled at 10°C per minute to safeguard sample integrity.

대표적인 적용 분야
Ideal for materials research, thermal treatment, annealing, sintering, and vacuum or low-pressure gas processing when combined with appropriate tubes and accessories. Suitable for use with quartz tubes under vacuum or low pressure below 0.2 bars, with temperature limits to 1000°C for vacuum applications.
구성 및 작동 안내
The furnace does not include processing tubes, vacuum flanges, or refractory ceramic blocks; these must be ordered separately based on application requirements. For 25 mm outer diameter tubes, an adaptor is required. Optional laptop and LabVIEW-based software are available for advanced temperature profile editing and data logging. Gas flow rates should be limited to under 200 SCCM to prevent thermal shock to quartz tubes. A two-stage pressure regulator is recommended for gas cylinders to maintain safe operating pressures below 3 PSI. For safety, consider operating the furnace inside a fume hood.
