VBF-1200X-300 Vertical Crucible Furnace with 22L Chamber, 1200°C Max Temp, 30-Segment Programmable PID Control
The VBF-1200X-300 is designed for laboratory tasks requiring precise high-temperature treatment such as sintering, annealing metals, and quality inspections. Its large vertical crucible chamber with a 22-liter capacity (320 mm diameter by 280 mm height) accommodates sizable samples or multiple crucibles, making it suitable for research institutes, universities, and industrial labs.
This furnace achieves rapid heating and cooling cycles with a maximum temperature of 1200°C for short durations (up to 30 minutes) and supports continuous operation at 1100°C. The heating elements are embedded within high-purity alumina fiber insulation, ensuring excellent temperature uniformity and energy efficiency. The double-shell steel construction with air cooling maintains a low external surface temperature for safer operation.
Key Features
- Large 22-liter heating chamber (320 mm ID x 280 mm height) for versatile sample processing
