| High Light | polished sapphire capillary tube ,sapphire tube for analytical instruments ,high-pressure sapphire capillary tube | ||
Our polished sapphire capillary tubes are precision-engineered using high-quality single-crystal sapphire (Al₂O₃), offering extreme hardness, excellent thermal resistance, and outstanding chemical stability. These tubes are ideal for applications requiring high-pressure, high-temperature, or corrosive environments, including analytical instruments, laser systems, microfluidics, and biomedical devices.
Sapphire’s broad optical transparency (UV 200 nm – IR 5 μm) makes it suitable for laser and infrared optical applications. Tubes can be provided as blank substrates, AR-coated pieces, or fully precision-polished to meet exact specifications.
Typical applications include:
Analytical & research instruments (HPLC, GC, ICP, spectroscopy)
Biomedical & microfluidic systems
Optical and laser guiding tubes
Semiconductor process components (CVD, MOCVD)
Aerospace & defense optical conduits

Q1: What material are the tubes made of?
A: Synthetic single-crystal sapphire (Al₂O₃), known for extreme hardness, chemical inertness, and high thermal stability.
Q2: Why “semi-polished” instead of “half-polished”?
A: “Semi-polished” indicates selective polishing of critical areas to balance performance and cost, whereas “half-polished” may sound informal.
Q3: How does sapphire compare to quartz or ceramic capillaries?
A: Sapphire is harder, more thermally stable, more chemically resistant, and has superior optical transmission from UV to IR.
Q4: Can these tubes be customized?
A: Yes. ID, OD, length, bore finish, end shape, and coatings can all be tailored to specific requirements.
