Round Fused Silica Tube OD 3mm ID 0.8mm Length 65mm Micro Spectrum Sampling

The Fused Silica Round Tube is a precision miniature tube with an outer diameter of 3mm, an inner diameter of 0.8mm and a length of 65mm, manufactured by precision drawing from high-purity fused silica. The tube features uniform wall thickness without bubbles or striae, while the straight and smooth inner bore provides an ideal channel for micro sampling and fiber protection. With excellent UV transmittance, an ultra-low thermal expansion coefficient and resistance to high temperature and strong acid and alkali, the tube delivers stable performance in demanding optical and laboratory applications. Its superior chemical inertness and low sample adsorption make it a reliable component for miniature precision optical testing equipment.

• High-purity fused silica by precision drawing: The drawn structure delivers uniform material quality along the full length.
• Uniform wall thickness without defects: The wall is free of bubbles and striae, ensuring consistent optical and mechanical behavior.
• Straight and smooth inner bore: The clean bore supports reliable fluid flow and fiber insertion.
• Excellent UV transmittance: High ultraviolet transmission supports spectral and UV optical applications.
• Ultra-low thermal expansion: Resistance to high temperature and strong acid and alkali, combined with crack-proof thermal shock behavior, ensures stability.

The Fused Silica Round Tube is designed for miniature optical and laboratory systems that require precise, inert tubing. It is widely used as a micro sampling tube for spectrum tests, delivering small sample volumes to measurement systems with minimal interference. In fiber optics, the tube serves as a miniature fiber protective sleeve, shielding fibers while allowing light transmission. The component is also adopted as a micro reaction pipeline for laboratories, providing a chemically inert channel for small-scale reactions. In analytical systems, it works as a carrier tube for fluorescence detection, supporting stable optical measurements. Additionally, the tube functions as a liner for mini UV light sources, combining UV transmittance with thermal durability.

• Precision forming of ultra-fine bore: Tight dimensional tolerance ensures accurate flow and fit in micro systems.
• Flat cut end without chipping: Clean end faces support reliable sealing and connection.
• No impurity precipitation and low adsorption: High-temperature service keeps samples pure, and the inner wall minimizes sample loss.
• Fit for miniature precision optical testing equipment: Compact size and consistent quality suit diverse micro optical instruments.
