  • Filtered by 0,2 µm filter
  • Suitable for UPLC / UHPLC / Ultra HPLC - instruments
  • Conforms to Methanol R1 and R2 according to Reag. Ph. Eur.
  • Conforms to the requirements of ACS for liquid chromatography suitability


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 a 'gradient grade' as well as 'isocratic grade'. This minimises the gradient effect of the solvent involved.
