Withdrawal systems for barrels and drums
Supplier: Merck
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.

2-Propanol, LiChrosolv®, gradient grade for liquid chromatography, Supelco®
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.

2,2,4-Trimethylpentane, Uvasol® for spectroscopy, Supelco®
Supplier: Merck
Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.
