NMR Tube

An NMR tube is a small, cylindrical glass container used in nuclear magnetic resonance (NMR) spectroscopy to hold liquid samples. Its uniform shape and material allow for precise placement inside an NMR instrument, where strong magnetic fields and radio waves analyze the sample's molecular structure. The tube's transparency and stability ensure accurate measurement without interfering with the magnetic environment. Typically, they are about 5-10 millimeters in diameter and can hold samples ranging from a few microliters to a few milliliters, facilitating detailed insights into the chemical composition of substances.
