Ethanol ≥99.9% (by GC), LiChrosolv®, gradient grade for liquid chromatography, Supelco®

Supplier: MilliporeSigma

Offering a high degree of UV transmittance, low particle count, low acidity and alkalinity, and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. They are produced from specially selected raw materials, and undergo a number of purification steps prior to final packaging. Since separations are normally carried out under gradient conditions in analytical HPLC, Merck Millipore offer solvents in ’gradient grade’ as well as ’isocratic grade’. This enables you to minimise the gradient effect of the solvent involved.
