Our NMR coaxial tubes consist of two separate NMR tubes: a 4 mm insert, which narrows to 2 mm towards the measurement area, and a matching 5 mm outer tube. The upper part of the insert fits precisely into the corresponding outer tube, ensuring the coaxiality of the two tubes. The lower part of the insert has a different length depending on the NMR spectrometer (Bruker = b, Varian = v).

The coaxial system allows the measurement of two liquids without mixing them.
