Complete Specifications
Aoxin Quartz manufactures this large, one-end-closed Quartz Tube (Model TQH200), specifically designed as a process chamber for VBF-1200X-H8 vertical bottom-loading furnaces. Measuring 8 inches in outer diameter and 13.4 inches in height, this robust chamber is crafted from high-purity fused quartz, enabling operation at temperatures up to 1200°C in atmosphere or 1100°C under vacuum. It features precisely located side ports (holes) near the open end, allowing for gas inlet/outlet, thermocouple insertion, or other process connections, making it ideal for various high-temperature material processing, annealing, and synthesis applications.
