High-purity sapphire single crystal offers high transmittance across a broad spectral range from ultraviolet to mid-infrared, along with good mechanical strength and chemical stability. It maintains stable optical performance under high pressure, high temperature, and corrosive environments, making it widely used in laser systems, infrared detection, industrial sensors, and high-temperature viewing windows.
The check valve features low opening pressure, good sealing performance, and long service life. It enables precise one-way control of microliter-volume liquids and is widely used in the liquid path systems of high-performance liquid chromatography, mass spectrometry, and other microfluidic analytical instruments.
Made from high-purity aluminum oxide (Al2O3) single crystal, the sapphire plunger rod undergoes oriented cutting and precision grinding to achieve a mirror-like surface finish and micron-level straightness. It enables precise, repeatable metering under high-pressure, high-frequency reciprocating conditions, with wear life significantly exceeding that of cemented carbide, making it a core motion component in precision microfluidic control.
The measuring ball is precision-ground from single-crystal sapphire and ruby. Its smooth surface, high hardness, and wear resistance help maintain good roundness retention under frequent contact, allowing coordinate measuring machines, profilometers, comparators, and other tactile probing systems to maintain long-term measurement stability and repeatability.
Made from high-purity ruby single crystal, the orifice achieves micron-level accuracy, with excellent orifice roundness and surface finish. It enables precise throttling and atomization control of liquids and gases, and is widely used in medical devices, inkjet printing, precision atomization, gas flow restriction in analytical instruments, as well as waterjet and laser cutting.
Jewel bearings use high-hardness (Al2O3) crystal material in place of conventional metal contact surfaces. They deliver low starting torque, low wear, and long service life under light loads and high speeds, and are widely used in precision instruments, micromotors, flow meters, and timing mechanisms.
