General description

This new range of premium quality NMR sample tubes feature color-coded banding and caps and a MHz rating that allows instant visual identification to tube grade and application. No more mix ups after cleaning.

Precision grade NMR tubes are made from Type I, Class A, thin-wall (0.38 mm) borosilicate glass for compatibility with ground joints, valves and vacuum racks. They are precision ground and highly polished for spinning stability and highest resolution for any NMR spectroscopy application. Thrift and disposable grade tubes are made from Type I, Class B, medium wall (0.43 mm) borosilicate glass. Disposable NMR tubes include the caps.
