EMSURE® grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. Merck declare the EMSURE® range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Supplier: Merck

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.

Supplier: VWR Chemicals

VWR® PFAS grade LC-MS solvents undergo a rigorous use test to ensure suitability for analysis of poly- and perfluoroalkyl substances resulting in an ultra low background of PFAS analytes. Using complementary methods a broad range of PFAS analytes are quantified to their detection limits by LC-MS.

Supplier: Merck

Additional to our high quality acetonitrile dried with low water content up to 10 ppm our DNA-/RNA synthesis reagents with its high quality, lowest water and acid content are best requirements for a reliable and reproducible DNA-/RNA synthesis with high yields. A wide variety of packaging types supporting specific synthesis instrumentations, for quantities from bottle to bulk, and the will to customized solutions completes our innovative offering.
