Tert-Butyl Methyl Ether - 1Ltr

Description

Catalogue Number	101845
Synonyms	MTBE, MTB, 2-Methoxy-2-methylpropane, Methyl tert-butyl ether
Description	tert-Butyl methyl ether
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.
