VBF-1200X-6A Automatic Bottom Loading Vertical Quartz Tube Furnace with 1200°C Max Temperature and Controlled Atmosphere
The VBF-1200X-6A furnace is engineered for laboratory applications requiring precise thermal treatment of materials within a controlled atmosphere. Its vertical design incorporates a 6-inch outer diameter quartz tube, enabling uniform heating and easy sample handling via an automatic bottom loading stage. This setup is ideal for processes such as material synthesis, annealing, and chemical vapor deposition where atmosphere control and temperature uniformity are critical.
Equipped with a programmable touch-screen panel, the furnace allows users to set heating and cooling rates, temperature dwell times, and gas pressures with high accuracy. The system supports integration with PC software and robotic arms for autonomous operation, facilitating continuous 24/7 processing in multi-furnace configurations.
Key Features
- Maximum working temperature of 1200°C (short term) and stable long-term operation at 1100°C.
- Two heating zones totaling 350 mm length with ±2°C uniformity over 120 mm.
- Fused quartz processing tube (150 mm OD × 144 mm ID × 600 mm length) for high purity and thermal stability.
- Water-cooled stainless steel sealing flanges with digital vacuum gauge, mechanical pressure gauge, and gas inlet ports.
- Sample stage diameter of 130 mm made from quartz plate, supporting large or multiple crucibles.
- Touch-screen control with two 50-segment temperature controllers and ±1°C accuracy; optional Eurotherm controller upgrade to ±0.1°C.
- Includes a 16 L/min recirculating water chiller to protect sealing components and maintain system integrity.
