General description
A wide range of MagniSolv deuterated solvents with extremely low residual water, excellent chemical purity, and the highest isotopic enrichment available can satisfy the most demanding requirements of researchers. Depending on application and sensitivity of the NMR spectrometer our offer solvents with deuteration degrees between 98% and 99.96%. In case of all the water soluble deuterated standard products, water content is specified according to both Karl Fischer and NMR.
