Frequently Asked Questions
1. What is the difference between standard and high-frequency NMR tubes?
High-frequency tubes, such as the DWK Kimble 600-800 MHz series, are manufactured with much tighter tolerances for camber and wall thickness to ensure signal stability in high-strength magnets.
2. Why use quartz tubes for EPR measurement?
Quartz glass, like that used in Hilgenberg EPR tubes, has superior microwave transparency and minimal background interference compared to standard borosilicate glass.
3. What are the common dimensions for standard NMR tubes?
Most routine laboratory NMR tubes feature an outer diameter of 5 mm and a length of 178 mm, though 3mm diameter versions are used for limited sample volumes.
4. Are "Economic" NMR tubes suitable for high-resolution research?
Economic tubes are ideal for education and routine screening, but for high-resolution 1H or 2D NMR experiments, professional-grade tubes are recommended for better signal-to-noise ratios.
