Merck 113351 Methanol for preparative chromatography Prepsolv® 2.5 L
Catalogue Number	113351
Synonyms	MeOH, Hydroxymethane, Methyl alcohol, Carbinol
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.
