MERCK 108101.2500 Tetrahydrofuran for Liquid Chromatography LiChrosolv® CAS No.109-99-9

 

Description
Catalogue Number 108101
Synonyms THF, Tetramethylene oxide, Oxolane, Butylene oxide
Overview With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
