OTF-1200X-III-S 24-Inch Three-Zone Tube Furnace with Quartz Tube and Flange, Up to 1200°C
The OTF-1200X-III-S is a laboratory tube furnace engineered for advanced thermal processing tasks such as sample annealing, diffusion, and sintering under various gas atmospheres. Its design accommodates precise temperature control across three distinct heating zones, enabling uniform and customizable thermal profiles over a total heating length of 610 mm. This furnace is suitable for research applications requiring stable high temperatures up to 1200°C for short durations and continuous operation at 1100°C.
This model integrates a fused quartz tube available in multiple diameters ranging from 50 mm to 130 mm outer diameter, allowing users to select the optimal size for their sample or process requirements. The quartz tube is compatible with vacuum and low-pressure environments (below 0.12 MPa absolute pressure), supported by included stainless steel 304 vacuum flanges with double high-temperature silicone O-rings. The furnace’s double-layer steel casing with cooling fans and high-purity fibrous alumina insulation ensures efficient heat retention and low external surface temperatures.

Typische Anwendungsbereiche
This tube furnace is widely used in materials research for synthesizing doped molybdenum disulfide and other advanced materials requiring controlled atmosphere heat treatment. It supports processes such as annealing, sintering, diffusion, and vacuum or low-pressure thermal treatments in academic and industrial laboratories.
Hinweise zur Konfiguration und zum Betrieb
The furnace includes two alumina fiber foam tube blocks to reduce heat radiation, a hook for sample handling, metric hex wrenches, and a pair of vacuum flanges. Users must fully insert ceramic blocks into the furnace chamber before heating. The quartz tube is designed for vacuum or low-pressure operation below 0.12 MPa absolute pressure. A two-stage pressure regulator is recommended on gas cylinders to maintain safe operating pressures below 3 PSI.
Optional accessories include hinged flanges for easier sample loading, digital molecular pumps for enhanced vacuum levels, computerized temperature control systems with recipe management, and various quartz boats or crucibles. The furnace can be remotely controlled via RS485 communication and supports integration with LabVIEW-based software for temperature profile editing and data logging.
