OTF-1700X-UL Split Tube Furnace with 60mm Alumina Tube, Vacuum Flanges, Valves, and Precise PID Temperature Control up to 1700°C
The OTF-1700X-UL is engineered for laboratory applications requiring precise heat treatment of samples within a controlled atmosphere or vacuum environment. It is designed to accommodate a high-quality alumina tube with an outer diameter of 60 mm and length of 1000 mm, enabling processes such as material synthesis, annealing, and sintering at elevated temperatures up to 1700°C.
This split tube furnace features a unique separable design allowing easy access for tube replacement and maintenance. The system includes stainless steel vacuum flanges equipped with needle valves and vacuum gauges, facilitating reliable sealing and monitoring of vacuum or gas flow conditions. The furnace’s temperature is controlled by a PID controller with auto-tune functionality, capable of programming up to 30 heating and cooling segments with ±1°C accuracy.

대표적인 적용 분야
Ideal for heat treatment processes requiring controlled atmospheres or vacuum, such as sintering ceramics, annealing metals, material synthesis, and research involving high-temperature reactions under inert or vacuum conditions.
구성 및 작동 안내
The furnace includes a pair of fibrous ceramic tube blocks to reduce heat radiation inside the tube; these must be fully inserted before heating. The vacuum pump is not included and should be ordered separately. Optional accessories include PC control modules, digital vacuum gauges, various tube sizes, and vacuum flange fittings. Users must ensure proper gas flow regulation with a two-stage pressure regulator limiting pressure below 3 PSI and avoid opening the furnace lid above 100°C to prevent thermal shock. The alumina tube is designed for vacuum and low-pressure use below 0.02 MPa, and graphite crucibles should not be used inside the alumina tube.
