image

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.
