OTF-1200X-IV 4-Zone Tube Furnace with Touch Screen Controller, 1200°C Max Temperature, and Optional Quartz Tube (80-130 mm OD)
The OTF-1200X-IV tube furnace is engineered for laboratory applications requiring controlled thermal environments such as annealing, diffusion, and sintering of samples under various atmospheres. Its design accommodates a long 900 mm heating zone divided into four independently controlled zones, enabling users to create either a uniform temperature or a smooth thermal gradient tailored to specific experimental needs.
This furnace includes a quartz tube available in three outer diameters (80, 100, or 130 mm) and a length of 1400 mm, with fibrous ceramic tube blocks to minimize heat radiation. Vacuum-tight flanges with integrated pressure gauges and ball valves are supplied for immediate vacuum or low-pressure operation, supporting vacuum levels down to 10-4 torr with appropriate pumps. The system is designed for safe operation under vacuum and low pressure below 0.2 bars.
Wichtigste Merkmale
- Four heating zones totaling 900 mm length (150+300+300+150 mm) with ±1°C temperature accuracy.
- Touchscreen controller with 30 programmable segments and PID control for precise temperature profiling.

Hinweise zur Konfiguration und zum Betrieb
The furnace includes one quartz tube and a pair of vacuum sealing flanges with integrated pressure gauges and valves. Optional quartz tube sizes can be selected based on sample or process requirements. The system is designed for vacuum or low-pressure operation below 0.2 bars; a two-stage pressure regulator is recommended to limit gas pressure below 3 PSI for safety. Vacuum pressures are safely maintained up to 1000°C. Gas flow rates should be limited to under 200 SCCM to prevent thermal shock to the quartz tube. RS485 communication allows for PC monitoring and control. Calibration of temperature is advised for accurate internal temperature readings. Overheating and broken thermocouple protections are built in for safe operation.
