Improved NMR sample tube shapes and inserts for standard tubes to shape the sample for greater homogeneity to provide symmetry of liquid sample and tube to a greater distance from the observe region for the same volume of sample as used in the prior art.

NMR sample shaper

An NMR probe having RF shield means to confine the RF magnetic field to an axial region having a length less than the length of the coil form.

NMR probe

Parasitic excitation of an NMR sample is minimized by providing shielding of the sample against RF pick-up from coil leads or like proximate conductive structure in the interior region of the RF coil.
