The Precision Glass Sleeve Tube is designed for miniature optical and analytical systems that require precise, protective tubing. It is widely used as a protective sleeve for miniature optical paths, shielding fibers and light guides from contamination, bending and mechanical damage. In analytical instruments, the tube serves as a liner for micro instruments, providing a clean and chemically inert channel for sample flow and optical transmission. The component is also adopted in chromatography lab fittings, where its accurate dimensions and smooth bore support reliable connections between columns and detectors. Additionally, the sleeve tube works as a precision sensor sheath, protecting sensing elements while allowing light or signals to pass through with minimal interference.
