OTF-1700X-VT Vertical Split Tube Furnace for High-Temperature Vacuum and Gas Heat Treatment up to 1700°C
The OTF-1700X-VT is engineered for laboratory applications requiring controlled atmosphere heating or rapid quenching of samples at elevated temperatures. Its vertical split tube design facilitates easy sample loading and unloading, making it ideal for processes such as single crystal growth and heat treatment under vacuum or flowing gases. The furnace supports integration with quenching systems and lifting or other motion mechanisms to enhance process flexibility.
This single-zone furnace can maintain continuous operation at temperatures up to 1600°C and reach a peak temperature of 1700°C for short durations. The heating tube, measuring 60 mm outer diameter, 54 mm inner diameter, and 1000 mm length, includes a 400 mm heating zone. High-purity aluminum fiber insulation and a double-layer shell with air cooling optimize energy efficiency and thermal stability. The system incorporates a stainless steel vacuum sealing flange equipped with a valve and meter, enabling vacuum levels down to 10⁻⁵ torr with appropriate pumps.
