The main points of choosing an NMR tube
-Concentricity and convexity: important indicators used to distinguish the strength of the applicable magnetic field.
-Tube material: Different detection conditions require the use of different materials of nuclear magnetic tubes.
-Tube surface finish: Lack of finish will affect the nuclear magnetic field, resulting in inaccurate detection results.
-Nuclear magnetic tube applicable frequency: Select the corresponding frequency of nuclear magnetic tube according to the spectrometer model, which can ensure the accuracy of the experiment and extend the service life of the nuclear magnetic resonance spectrometer.
Sapphire (Al2O3 single crystal) has extraordinary hardness and high melting temperature around 2000°C. Due to its single crystal structure, it has outstanding chemical resistance to corrosive solvents, including HF acid.
The sapphire nuclear magnetic resonance (NMR) tube is a high-performance vessel specifically designed for nuclear magnetic resonance experiments, made of high purity sapphire material. Due to the excellent optical and mechanical properties of sapphire, this NMR tube offers significant advantages in precise scientific research and analysis.

FAQ
1. Q: Are sapphire tubes easy to break?
A: Sapphire tubes are strong due to their hardness but can be prone to breakage under high impact or stress due to their brittleness.
2. Q: Compared with the quartz tubes, what is the advantage of sapphire?
A: Compared with quartz tubes, sapphire tubes are much harder, much better performance and they can be used in harsh situations due to their higher temperature resistance and scratch resistance.
