NMR tube pipettes

From NMR Wiki

NMR tube pipettes have long narrow tips that can reach bottom of NMR tubes and transfer samples with minimum losses and avoid forming bubbles.

Glass Pasteur pipettes

Tip: if you would like to minimize loss of sample on smearing over the inner pipette surface, draw sample only into the tip of pipette and transfer sample in a few steps. This technique can be very useful when working with aqueous samples of limited volume.
