Merck 111727 Ethanol Ethanol gradient grade for liquid chromatography LiChrosolv®. Bitkisel Kökenli Etil Alkol KURUMSAL SATIŞ TAPDK İzinli
Ethanol gradient grade for liquid chromatography LiChrosolv® 2.5 L

Merck 111727 Ethanol Ethanol gradient grade for liquid chromatography LiChrosolv®.

Description
Catalogue Number	111727
Synonyms	Ethyl alcohol, EtOH
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.
