GSL-1700X-VGQ-60 Inert Gas Quenching Vertical Tube Furnace with 1700°C Max Temperature and 60mm Alumina Tube
The GSL-1700X-VGQ-60 is engineered for precise thermal processing of air-sensitive materials requiring rapid quenching under an inert atmosphere. It enables controlled heating up to 1700°C within a vertical alumina tube, followed by swift cooling in a dedicated quenching chamber to avoid contamination from liquid quenching media. This design is ideal for materials research and development where oxidation or contamination during cooling must be prevented.
Samples up to 50mm diameter and 65mm length can be processed inside a 60mm diameter, 850mm long high-purity alumina tube. The quenching chamber, positioned atop the furnace, is vacuum-sealed and equipped with observation windows, enabling vacuum levels down to 10-5 torr with a turbopump. The heated sample is manually or electrically lifted from the heating zone into the quenching chamber, where inert gas rapidly cools it from high temperature.

대표적인 적용 분야
This furnace is suited for heat treatment of oxidation-sensitive materials, rapid thermal processing, sintering, annealing, and quenching of metals, ceramics, and composites under controlled inert atmospheres or vacuum. It is particularly useful in research environments requiring contamination-free quenching and precise temperature control.
구성 및 작동 안내
The system includes vacuum-sealed alumina tube with flanges, valves, vacuum gauge, and thermal blocks. The quenching chamber features a vacuum-sealed lifting rod operated manually or optionally by electric lift. An electric gate valve prevents radiation from the heating tube during quenching. Gas inlet and outlet ports accept 1/4″ OD stainless steel tubing with needle valves.
A water chiller is required but not included. Users should install a two-stage pressure regulator on gas cylinders to limit pressure below 3 PSI for safety. The MoSi2 heating elements must not be held between 400°C and 700°C for extended periods in oxidizing atmospheres to avoid damage. Calibration of temperature is recommended before use for accuracy.
