OTF-1200X-III-HVC-LD Three-Zone Tube Furnace with High Vacuum Station and 4-Channel Mass Flow Controller for CVD
The OTF-1200X-III-HVC-LD is engineered to support advanced laboratory processes requiring precise thermal and atmospheric control, such as chemical vapor deposition (CVD), diffusion, and other heat treatments under vacuum or protective gas environments. This system integrates a three-zone tube furnace with a high vacuum station and a multi-channel mass flow controller to enable complex gas mixing and vacuum conditions.
The furnace utilizes a fused quartz tube as the processing chamber, suitable for vacuum and low-pressure applications below 0.2 bar. It achieves a maximum temperature of 1200°C with continuous operation up to 1100°C. The heating zones are independently controlled by three precision PID temperature controllers, each managing a 300 mm section of the 900 mm total heating length, ensuring uniform temperature distribution and programmable heating profiles.

구성 및 작동 안내
The system includes one fused quartz processing tube and a vacuum sealing assembly with stainless steel flanges and valves. Optional accessories such as bubblers or evaporators for CVD can be ordered separately. For safe operation, a two-stage pressure regulator must be installed on gas cylinders to limit pressure below 3 PSI. Gas flow rates should be kept under 200 SCCM to prevent thermal shock to the quartz tube. Temperature calibration is recommended for accurate internal furnace readings.
