Shigemi tube

Today NMR spectroscopy deals more and more with reduced sample amount . However , it is not often possible to use a volume matched NMR probe . The solution so far was to dilute the sample to obtain a suitable volume to fill 5mm NMR tube, or to use special susceptibility matched tubes .
Shigemi NMR tube use different material to match the susceptibility of solvents that user can obtain good homogeneity NMR spectrum though sample amount is less than 300 ul .

Available tubes for solvent CDCl₃(CMS)，CD₃OD(MMS)，D₂O(BMS)，DMSO( DMS)。
Tube size : 2.5mm、3mm、5mm、8mm、10mm。

Reduced wall thickness (BMS-T) enhance sensitivity by 16% .

 Shigemi also provide special : co-axial tubes , ²⁹Si or ¹¹B  application NMR tube。
