OTF-1200X-VT-III-4 Three Zone Split Vertical Tube Furnace with 1200°C Max, 4″ Quartz Tube, and Vacuum Flanges
The OTF-1200X-VT-III-4 vertical tube furnace is engineered for laboratory applications requiring precise thermal processing under vacuum or controlled gas atmospheres. Its design facilitates rapid heating and quenching of samples within a vacuum-sealed quartz tube, making it well-suited for quenching tests and accurate temperature measurements in materials research.
This furnace incorporates a 4-inch outer diameter quartz tube sealed with stainless steel vacuum flanges, enabling reliable vacuum operation down to approximately 0.1 torr, depending on the vacuum pump used. The vertical orientation and split design allow easy access and sample handling, while the heavy-duty mobile base provides portability within the laboratory.

Typische Anwendungsbereiche
This vertical tube furnace is ideal for materials science research involving rapid thermal processing, quenching experiments, and controlled atmosphere heat treatments. It supports vacuum and low-pressure gas environments, enabling studies of oxidation, reduction, sintering, and annealing processes under precisely controlled temperature profiles.
Hinweise zur Konfiguration und zum Betrieb
The furnace includes a standard 4″ quartz tube and stainless steel vacuum flanges with integrated vacuum gauge and valves. Optional quartz tubes of different diameters and various fittings such as KF25 adapters and Swagelok® tube fittings are available to enhance vacuum efficiency and gas flow control. Users should limit gas flow rates to below 200 SCCM to prevent thermal shock to the quartz tube and maintain vacuum pressures safely below 1000°C. Installation of a two-stage pressure regulator on gas cylinders is recommended to maintain safe operating pressures below 3 PSI. Calibration of the temperature controller before use is advised for accurate temperature measurement inside the tube.
