OTF-1200X-PV-HVS High Vacuum Compact Tube Furnace with 1200°C Max Temperature, 8″ Quartz Heating Zone, and Integrated Turbo Vacuum System
The OTF-1200X-PV-HVS is engineered for laboratory applications requiring precise high-temperature treatment under high vacuum conditions. It integrates a compact tube furnace capable of reaching temperatures up to 1200°C with a high-performance turbo molecular vacuum pump system. This combination enables controlled atmosphere processing with vacuum levels reaching as low as 10^-6 torr, suitable for advanced material synthesis, thin film deposition, and vacuum annealing.
The heating chamber consists of a 60 mm outer diameter quartz tube sealed with vacuum flanges, allowing gas inlet/outlet and thermocouple feedthroughs. The system includes a mechanical vacuum gauge and a KF40 clamp connection to the turbopump, ensuring reliable vacuum integrity. Temperature is regulated by a PID controller with auto-tune capability, supporting up to 30 programmable segments for ramping, dwelling, and cooling with ±1°C accuracy.
