OTF-1500X-GB 1500°C Split 2″ Tube Furnace with Dual Glovebox and Integrated Purification System for Air-Sensitive Material Processing
The OTF-1500X-GB is engineered to facilitate precise thermal processing of materials that are highly sensitive to oxygen and moisture. It integrates a splitable tube furnace capable of reaching temperatures up to 1500°C with a dual glovebox system that maintains an inert atmosphere with oxygen and humidity levels below 1 ppm. This configuration allows users to perform heat treatments and subsequently transfer samples directly into the glovebox environment for further manipulation without exposure to ambient air.
The system’s design includes a 2-inch diameter alumina tube (50 mm outer diameter, 40 mm inner diameter, 1000 mm length) housed within a double-layer steel casing with air cooling to keep the external surface temperature below 60°C. High purity fibrous alumina insulation and a special refractory inner coating enhance energy efficiency and furnace longevity. The split cover features interlock protection to ensure power is cut if opened during operation, enhancing user safety.
Key Features
- Dual glovebox with fully openable tempered glass front panel and stainless steel 304 chamber for controlled inert atmosphere.
- Purification system maintaining oxygen and water vapor concentrations below 1 ppm using inert gases (N2, Ar, He) and automatic regeneration with H2-containing gas mixture.
- Split tube furnace with 2″ alumina tube and air-cooled double steel casing for temperature control and safety interlock.
- Integrated vacuum system including a 240 L/min double stage rotary vane pump for maintaining low pressure conditions.
- Multiple KF40 feedthroughs and large antechambers for sample and tool transfer without compromising atmosphere integrity.
- Automatic pressure control within glovebox to maintain constant internal pressure.
- Energy-saving high purity fibrous alumina insulation and ceramic tube blocks to minimize heat radiation losses.

Typical Applications
Ideal for research and development involving air-sensitive materials such as battery components, catalysts, and advanced ceramics requiring controlled atmosphere heat treatment and handling.
Enables synthesis, annealing, and processing workflows where exposure to oxygen and moisture must be minimized to preserve sample integrity.
Configuration & Operating Notes
The system includes a separate table for the furnace and multiple KF40 feedthroughs for customization. Optional larger diameter tubes (3″ or 4″) are available at additional cost. The purification system automatically regenerates and purges to maintain ultra-low oxygen and moisture levels.
Users should ensure compatibility of internal components with the selected inert gas, especially when using argon. Gloves are consumables and require periodic replacement. The interlock safety feature prevents furnace operation if the split cover is opened.
