DIMETHYL SULFOXIDE FOR SPECTROSCOPY Uvas

Description
Catalogue Number 102950
Synonyms Methanesulfinylmethane, Methyl sulfoxide, Dimethyl(oxido)sulfur, DMSO
Overview Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.
