Clear Quartz Tube

Clear Quartz Tube is a high-purity quartz glass tube rated for stable operation up to 300°C (with short-term tolerance to about 350°C), offering strong chemical inertness to most acids (except hydrochloric acid) and a very low coefficient of thermal expansion that lets it withstand rapid temperature swings — including quenching from 300°C into cold water — without cracking. Its high-transparency, bubble-free construction gives excellent light transmission, and its high electrical resistance makes it a stable insulator even at elevated temperatures. It is offered in inner diameters from 5mm to 300mm with customizable thickness, standard 1000mm length and tight ID tolerances. Manufactured directly by Shanghai Chenqiao Biosciences Co., Ltd, it is sold across North America, Central/South America, Western and Eastern Europe, Australasia, Asia, the Middle East and Africa.
