General description

Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol﹤TMSYMBOL>﹤/TMSYMBO﹤WBR>L> 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﹤TMSYMBOL>﹤/TMSYMBO﹤WBR>L> solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified.
