The One-End Sealed Fused Silica Tube is a precision miniature vessel with an outer diameter of 4mm, an inner diameter of 2mm and a total length of 35mm, with one end hermetically heat-sealed. The tube is integrally formed from high-purity fused silica, and the sealed end is free of cracks and pores, providing a reliable closed chamber for micro samples. The uniform transparent tube wall delivers excellent UV transmittance, while the ultra-low thermal expansion coefficient ensures resistance to high temperature and acid and alkali. With anti-cracking behavior under temperature alternation and long-lasting sealing performance, the tube is a dependable component for laboratory and optical applications.

The One-End Sealed Fused Silica Tube is designed for miniature sample handling and optical testing systems that require an inert, sealed chamber. It is widely used as a sealed micro sample reaction tube, containing small volumes of reactants without contamination. In illumination systems, the tube serves as a liner for standard light sources, combining optical transparency with thermal durability. The component is also adopted as a specimen tube for spectral testing, providing a clean, UV-transparent path for analysis. In laboratory heating, it functions as a high-temperature heating vessel, withstanding thermal cycling without cracking. Additionally, the tube works as a sealed carrier tube for fluorescence detection, protecting samples while allowing reliable optical measurement.
