Product Description
Small-Size Sapphire Tubes Polished Wear-Resistant for High-Temperature Pressure Sensors
Sapphire tubes small size are precision tubular components fabricated from high - purity single - crystal sapphire. They are well - suited for high - end fields such as microfluidics, laser optics, sensors, and medical devices. ZMSH offers customized services, allowing for the adjustment of parameters including inner/outer diameter, wall thickness, surface finish, and crystal orientation to meet the requirements of different application scenarios. Moreover, it supports rapid delivery for small - batch orders, ensuring the stable operation of the products in extreme environments.
Key Characteristics
1. Ultra - high Mechanical Strength: Capable of withstanding the impact of high - pressure micro - channels, with a bending strength ranging from 500 to 700 MPa.
2. High - temperature Resistance: Can operate stably at 1500 °C, making it suitable for high - temperature scenarios such as thermopile sensors and combustion chamber monitoring.
3. Optical Transparency: It has a wide spectral transmission range from 0.2 to 5.0 μm, which is appropriate for laser transmission in the ultraviolet and infrared spectra.
4. Chemical Inertness: Resistant to strong acids, strong bases, and organic solvents, suitable for use in harsh environments such as microfluidic chips and semiconductor manufacturing.
5. Low Adsorption: The surface is modified to be hydrophobic, reducing residues and making it applicable for biomedical fluid transportation.

Primary Applications
(1) Microfluidics and Biomedical
· Cell Culture Chips: Construct a stable micro - environment to monitor cell metabolism in real time.
· Micro - and Nano - fluidic Transportation: Compatible with high - pressure microfluidic systems, used for nanoparticle sorting or single - cell manipulation.
· Medical Implants: Ultra - thin - walled tubes (<100 μm) are used to fabricate vascular stents that can withstand the in - vivo environment.
(2) Laser Optics
· Ultraviolet Laser Guiding: Achieve efficient transmission in 355 nm/266 nm lasers for precision material processing.
· Infrared Fiber Coupling: Transmit CO₂ lasers (10.6 μm) with low loss (<0.2 dB/m).
(3) Sensors
· High - Temperature Pressure Sensors: Micro - tubes are integrated with piezoelectric thin films to detect pressure pulsations in engine combustion chambers with a frequency response of 10 kHz.
· Micro - Thermopiles: Encapsulated within sapphire tubes to detect the concentration of CO₂ in exhaled breath with an accuracy of ±2 ppm.
(4) Scientific Research and Military
· Extreme Ultraviolet (EUV) Optics: A 3 - mm tube is used as a window for lithography light sources to protect against 13.5 - nm wavelength radiation.
· Deep - Space Probes: Protect the optical instruments on the exterior of spacecraft, withstanding extreme temperature differences.
