NMR Test Tubes


Wako off ers glass test tubes for NMR analysis. High grade glass tubes are available at reasonable prices. We provide two types of tubes having diff erent outside diameters; S-Type (Standard), and HG-Type (High Grade). While the S-Type has a relatively wider OD, the HG-Type has a narrower OD allowing for better accuracy of the analysis. In a high frequency range, it is advisable to use the HG-Type with less noise. Two diff erent lengths of tube, 7- and 8-inch, are also available, allowing you to choose a suitable length to fi t your NMR system. Samples are available on request.
