OTF-1200X-III-8 Three-Zone Split Tube Furnace with 35.4″ Heating Length, 8″ ID Quartz Tube, Up to 1200°C
The OTF-1200X-III-8 is engineered for laboratory processes requiring precise thermal treatment such as annealing, diffusion, and sintering of materials under various gas atmospheres. Its design supports applications demanding a stable and uniform temperature environment over an extended length, making it suitable for advanced material synthesis and research.
This tube furnace features a total heating zone length of 900 mm (35.4 inches), divided into three independently controlled zones of 300 mm each. The split-able structure allows for flexible sample placement and temperature gradient creation. The included quartz tube has an 8-inch inner diameter and a length of 1524 mm (60 inches), sealed with stainless steel vacuum flanges equipped with double high-temperature silicone O-rings and water cooling jackets to maintain vacuum integrity and thermal stability.

Used in synthesis of doped materials such as Ta and Nb-doped MoS2, as documented in scientific publications. Suitable for vacuum and gas atmosphere treatments requiring precise temperature gradients.
Hinweise zur Konfiguration und zum Betrieb
The furnace includes a quartz tube with vacuum sealing flanges, pressure gauge, and ball valves for immediate use. Optional accessories include vacuum pumps, digital vacuum gauges, mass flow controllers, and gas mixing systems. A PC control module and laptop with LabVIEW software are available for enhanced temperature profile management and remote operation. Proper installation of a two-stage gas pressure regulator is recommended for safe gas supply. Ceramic tube blocks must be fully inserted before heating to block heat radiation. The split cover features interlock protection for operator safety.
