2.5 mm NMR capillary system kit

The use of New Era capillary system kits enables not only to speed up experiments for very soluble samples but also to handle sub-mM concentrations and sample volumes of 15 to 115 µL.Samples are placed into disposable capillaries and gradient -shims are done only on the sample itself. Other advantages include the possible reduction of temperature gradient effects on the water signal in a 5mm tube and potentially better resolution on smaller diameter samples. The residual (annular) space between the capillary and the tube can be filled with a lock or reference material as opposed to adding these materials directly into the sample. This not only keeps your sample as concentrated as possible, it allows easy access to multinuclear (¹H, ¹⁹F, ²H) measurements.
