Wilmad^® external reference system

SB.32

Perfect for isolating your reference solution from your sample, this double layered tube provides extra protection for toxic samples in NMR spectroscopy as well.

Each insert fits with precision into the outer tube.The flat bottom forces the reference solution upwards between the inner and outer tubes.

Simple to use, just place your sample in the insert and add a few drops of reference solution to the bottom of the outer tube. When pushing the inner tube downward, the reference solution is forced upwards and forms a thin film, about 50 μL thick between the tubes.
