OTF-1200X-II-80HG-UL Two-Zone Tube Furnace with 1200°C Max, 80 mm OD Quartz Tube, Liquid Evaporator, Humidity and Hydrogen Detectors, and Safety Shutoff Valve
The OTF-1200X-II-80HG-UL is engineered to meet the demanding requirements of hot corrosion studies and chemical vapor deposition (CVD) processes involving hydrogen gas under precisely controlled humidity conditions. This tube furnace incorporates two independently controlled heating zones, each 200 mm in length, allowing a total heated length of 400 mm with a stable constant temperature zone of 150 mm. The system accommodates an 80 mm outer diameter high-purity quartz tube, suitable for high-temperature processing up to 1200°C.
A key feature is the integrated liquid evaporator designed for vaporizing liquid precursors, facilitating the delivery of mixed hydrogen and vaporized chemicals into the reaction chamber. The evaporator includes a stainless steel container with a 600 ml capacity, heated up to 250°C with programmable temperature control. The furnace also incorporates a precision digital humidity monitor capable of measuring relative humidity from 0 to 100% with ±1.5% full scale accuracy, enabling fine adjustment of moisture content in the gas flow.
Wichtigste Merkmale
- Two heating zones with PID-controlled temperature accuracy of ±1°C and 30 programmable segments for heating and cooling profiles.
- High-purity alumina fiber insulation and double shell casing with cooling fans for energy efficiency and safety.
- Integrated liquid evaporator with temperature-controlled stainless steel container for vapor delivery.
- Digital humidity monitor with KF25 flange adaptor for real-time moisture measurement and control.
- Honeywell hydrogen gas detector with automatic shutoff valve to prevent hazardous leaks.
- Two float flow meters (50-500 ml/min) for precise gas flow control of hydrogen and CVD gases.
- Vacuum-compatible quartz tube with SS304 flanges enabling vacuum levels down to 10^-5 torr using a turbopump.
