Quartz Tube with Flange Assembly for CVD and Furnaces

Demande de solution pour le verre de quartz

Product Overview

This quartz tube with flange assembly is designed for laboratory, semiconductor, and furnace applications requiring a sealed reaction environment. The tube is manufactured from high-purity fused quartz and can be paired with our precision-machined flange system to achieve secure, reliable connections for gas flow, heating, and vacuum operations.

The assembly provides excellent thermal stability, chemical resistance, and sealing performance, making it suitable for CVD processes, thermal treatments, material synthesis, and research experiments involving inert or reactive gases.
