Frequently Asked Questions
1. Why are NMR closing caps available in different colors?
Color-coded caps from Hilgenberg allow researchers to visually categorize different sample types, concentrations, or experiment batches at a glance.
2. Will a 5mm cap fit all NMR tubes?
Caps are diameter-specific; you must ensure you select the 5mm Hilgenberg caps for standard tubes and the 3mm versions for smaller-diameter high-frequency tubes.
3. What is the benefit of using a dedicated NMR tube rack?
The Bel-Art NMR tube rack is designed with the correct spacing and depth to prevent long, thin tubes from tipping or breaking during transport or storage.
4. Are Hilgenberg caps sold individually?
To ensure laboratory efficiency, these caps are typically supplied in packs of 50, providing a reliable stock for routine spectroscopic applications.
