NMR Tubes with thread

Our new NMR tubes with thread are suitable for low vacuum applications as well as for sample filling under protective atmosphere or degassing of samples within the tube. The large volume beneath the threaded head can be used for additional absorber packing within the tube, like silica gel or nano sieves. Based on borosilicate glass 3.3, these tubes have a high thermal shock resistance. The well known thread 8-425 in the field of chromatographic applications allows the use of different screw caps and seals fitting best to used solvents and samples. We also offer pre-dried (free of remaining water) tubes.
