Sapphire glass tube transparent single-crystal alumina electro-insulation properties

Product description

Sapphire capillary tubes, crafted from single crystal sapphire, are renowned for their extraordinary resilience and durability, making them the optimal choice for demanding environments involving extreme physical conditions.

Due to the inherent strength and exceptional properties of sapphire, such as its ability to endure high temperatures, significant pressure levels, and aggressive chemical exposures, these capillary tubes are incredibly reliable in critical applications.Particularly noteworthy is the sapphire capillary tube with an inner diameter of 0.6mm and a wall thickness of 0.2mm, designed to withstand internal pressures exceeding 100 MPa. This capability highlights the tube's robustness in handling high-pressure scenarios without compromise.Leveraging over two decades of expertise, our manufacturing process has been finely tuned to produce sapphire capillary tubes of superior quality.

We are adept at crafting tubes with minute inner diameters as small as 0.1mm, wall thicknesses down to 0.1mm, and lengths that can reach up to 1500mm. This precision in manufacturing allows us to meet the specialized needs of our clients across various industries, ensuring performance and quality that set industry benchmarks. Whether for analytical applications in laboratories, in aerospace engineering, or in high-tech manufacturing processes, our sapphire capillary tubes offer unparalleled performance and reliability.
