A precision-machined glass tube designed for sample analysis in nuclear magnetic resonance (NMR) spectroscopy. Fabricated from ultra-pure borosilicate glass to ensure minimal background interference and optimal signal clarity. 

Key Features：

✔ Uniform Wall Thickness – Guarantees consistent magnetic field penetration for accurate spectral data.

✔ High-Purity Glass – Reduces impurity-related signal noise in NMR measurements.

✔ Precision-Cut Ends – Ensures proper fitting in NMR spectrometers and sample changers.

✔ Low Volume Design – Minimizes sample requirements while maintaining detection sensitivity.

✔ Chemical Resistance – Withstands a wide range of organic solvents and reactive samples.
