VBF1200XVGB Glovebox-Compatible Split-Type Vertical Furnace with Quartz Tube Chamber, 1100°C Max Temperature
The VBF1200XVGB is engineered for precise heat treatment of materials that are highly sensitive to moisture and oxygen exposure. Its vertical well furnace design allows direct connection to a glovebox via a KF200 flange, enabling seamless transfer of samples under controlled inert atmospheres such as argon or nitrogen. This integration facilitates uninterrupted processing workflows for sensitive samples immediately after thermal treatment.
The furnace features a sealed single-end closed quartz tube chamber (φ200 × 340 mm) that acts as the reaction environment, surrounded by a high-purity alumina fiber insulation with imported high-temperature alumina coating. The split-type configuration separates the control box from the furnace body, allowing operation outside the glovebox for user convenience and safety.
Wichtigste Merkmale
- Maximum heating temperature of 1100°C with continuous operation up to 1000°C and holding time ≤30 minutes at peak temperature.
- Quartz tube sealed chamber with stainless steel water-cooled sealing flange and fluororubber O-ring for airtight operation.
- PID automatic temperature control via 858 series controller with 50 programmable segments and ±1°C accuracy.
- Gas inlet and outlet system equipped with compression fittings, ball valve, and stainless steel needle valve for controlled atmosphere management.
- Includes three-layer perforated stainless steel rack and stainless steel crucible for sample placement.
- Recommended inert gases: argon or nitrogen supplied from a 40 L cylinder with pressure regulator and PTFE tubing.
- Split-type design enhances operational flexibility by separating control electronics from the furnace chamber.

Typische Anwendungsbereiche
This furnace is ideal for thermal processing of materials that require strict exclusion of moisture and oxygen, such as advanced battery materials, sensitive catalysts, and air-sensitive chemical compounds. Its glovebox compatibility allows direct sample transfer without atmospheric exposure, supporting research and production workflows in materials science and chemical synthesis.
Hinweise zur Konfiguration und zum Betrieb
The furnace requires connection to an external water chiller (recommended model: KJ-5300) for the water-cooled sealing flange. The chiller is not included and must be procured separately. Proper grounding and circuit protection per specifications are essential for safe operation. Gas supply must be regulated with appropriate pressure regulators and PTFE tubing. Optional PC software is available for advanced temperature programming and data export. Users should ensure all seals and connections are properly maintained to preserve the inert atmosphere integrity.
