Fused Quartz Tubing 28mm ID x 32mm OD 48in Technical Glass Capillary

Description

Product Overview

The 28mm ID × 32mm OD fused quartz tubing offered by Technical Glass Products is engineered for the most demanding scientific and industrial applications. Constructed from high‑purity fused quartz with a silica content of 99.998%, the material exhibits exceptional chemical resistance, low thermal expansion, and optical clarity. The tube measures 48 inches in length, providing ample reach for complex setups while maintaining a uniform wall thickness that supports consistent fluid dynamics. Its softening point of 1683 °C and operational temperature limit of 1200 °C allow it to perform reliably in extreme heat environments, making it suitable for furnace work, high‑temperature synthesis, and advanced optical experiments. The product is supplied in a single‑count package, with package dimensions of 56 × 10 × 10 inches and a weight of approximately one pound, ensuring easy handling and storage.

Usage

Designed for laboratory and industrial settings, this fused quartz tubing excels in applications that demand high thermal stability and chemical inertness. Researchers use it for gas flow lines in chromatography, as a conduit for high‑temperature chemical reactions, and as a component in optical fiber assemblies where purity and low attenuation are critical. In industrial contexts, the tubing serves as a protective sheath for sensors operating inside furnaces, as a conduit for molten metal transfer, and as a component in semiconductor manufacturing processes that require contamination‑free environments. Its ability to endure rapid temperature cycling without cracking makes it a reliable choice for experiments involving thermal shock testing, plasma generation, and laser‑induced processes. The tube’s dimensions are compatible with standard laboratory fittings, allowing seamless integration with existing equipment.
