Merck offers a broad variety of withdrawal systems that are tailor-made for barrels and drums. They are designed to ensure safe, easy and efficient solvent withdrawal-even of residual quantities-while meeting all relevant safety regulations.
The integrated solvent supply systems directly connect the solvent to the instrument or product line where it is needed. We provide systems for manual pressure build-up as well as inert gas pressurising, supplemented by a comprehensive selection of reducers, adapters and couplings that allow easy interconnection of all components. This way the user can precisely manage his solvent flow and thus optimizes the processes-and at the same time minimizes risks for the employees and the environment.

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.
