OTF-1700X-VT-III Three-Zone Splittable Vertical Tube Furnace for Vacuum and Gas Heating up to 1700°C
The OTF-1700X-VT-III is engineered to meet demanding laboratory requirements for high-temperature processing of samples under vacuum or controlled gas atmospheres. Its vertical tube design facilitates uniform heating and easy sample insertion, making it suitable for applications such as single crystal growth and advanced heat treatment. The furnace can be integrated with quenching systems and lifting or motion mechanisms to enhance process flexibility.
This model features a splittable tube furnace with three independently controlled heating zones, each 200 mm in length, providing a uniform temperature zone of 450 mm with ±3°C stability. The tube dimensions are 60 mm outer diameter, 54 mm inner diameter, and 1000 mm length. It supports continuous operation up to 1600°C and short-term heating to 1700°C, with recommended heating rates adjusted to ensure temperature uniformity and equipment safety.
