Wilmad NMR Reference Standards are packaged in ultra-high field precision tubes to guarantee their performance in experiments over 600 MHz.
• Certificate of Analysis (CofA) supplied with each standard
• Meet or exceed requirements set by NMR spectrometer manufacturers
• All standards are backward compatible with NMR experiments below 600 MHz
