Semi-Polished & Fine-Ground Sapphire Capillary Tubes for Advanced Optical & Semiconductor Applications

Product Overview:

Our Semi-Polished and Fine-Ground Sapphire Capillary Tubes combine two distinct surface finishes for optimal performance in demanding applications. One half of the tube is semi-polished, providing cost-effective surface treatment, while the other half features fine-ground and optically polished surfaces for superior fluidic smoothness and light transmission. This dual-surface design offers a unique balance between precision and cost-efficiency, making it ideal for applications requiring both high structural strength and exceptional optical or fluidic properties.

Features:

• Dual-Surface Design: One half of the tube is semi-polished for a cost-effective solution, and the other half is fine-ground and optically polished for superior smoothness and light transmission.

• Extreme Hardness & Durability: Sapphire’s Mohs 9 hardness ensures superior scratch resistance and long-term reliability under harsh conditions.

• Customizable Dimensions: Available in a wide range of sizes, from inner diameters as small as 0.1 mm and outer diameters down to 0.2 mm, with wall thicknesses starting at 0.1 mm.

• High-Temperature & Pressure Resistance: Capable of withstanding extreme environments, including high-pressure and high-temperature conditions.

• Optical Transparency: Sapphire’s broad optical transmission range (0.3 μm – 5 μm) enables use in laser optics and spectroscopy.

• Chemical Stability: Excellent resistance to corrosion and chemical degradation, making these tubes ideal for industrial, medical, and analytical uses.

Specifications:

Applications:

• Medical & Biological Diagnostics: Used in microfluidic chips, DNA sequencing devices, and blood analyzers, where both smoothness and durability are essential for fluid handling and sample integrity.

• Laser & Optical Systems: Optical sleeves, beam guides, and protective housings where both polished and semi-polished surfaces are required for optimal light transmission and protection.

• Semiconductor & Electronics: Gas and liquid transport in CVD reactors, plasma etching chambers, and vacuum systems. Sapphire’s high-temperature and corrosion resistance ensure reliability and longevity.

• Chemical Analysis & Chromatography: Ideal for HPLC, GC instruments, and other analytical tools, providing smooth internal surfaces that minimize sample adsorption and enhance detection accuracy.

• Aerospace & Defense: Designed for high-vibration, high-temperature fluid regulation and optical sensing, ensuring structural integrity in extreme conditions.

• Energy & Petrochemical Fields: Used in high-pressure fluid lines and corrosive environments, offering thermal and chemical resistance suitable for aggressive industrial applications.
