Supplier: Merck

Desiccant suitable for desiccators to remove water, and for drying most gases and liquids (apart from strongly acidic and basic gases, organic solvents or alkaline liquids). The product contains iron salts as the indicator. Colour change is from orange to colourless at approx. 7/10 g adsorbed H₂O/100 g silica gel. Regeneration can be performed as often as required at 130 to 140 °C in a drying oven for approx. 3 hours.

Supplier: Merck

RP-2, RP-8 and RP-18 are based on silica gel 60 modified with aliphatic hydrocarbons. The chain length, in combination with the degree of modification, defines the ability to tolerate water in the solvent system and strongly affects retention. Migration time increases in the order RP-2, RP-8 and RP-18 using the same solvent composition. RP-8 and RP-18 can be run with up to 60% water in the solvent system.

Supplier: Merck

HPTLC plates, unmodified silica gel 60
This range of plates uses an optimised Merck silica gel 60 with a particle size of only 5 to 6 µm, which results in higher packing density and a smoother surface, therefore, reducing band diffusion. Less sample is required, 0,1 to 0,5 µl than for classic TLC.

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 minimises the gradient effect of the solvent involved.

Supplier: Merck

A range of cleansers, for machine washing and rinsing, that have been developed to meet the cleaning requirements for glassware and small equipment in the laboratory.

Supplier: Merck

TLC plates, unmodified silica gel 60
Merck silica gel 60 has a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. This smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 250 μm and particle size of 10 to 12 µm. Two inorganic fluorescent indicators for UV detection of colourless substances.

Ammonium heptamolybdate tetrahydrate ISO, ACS, Reag. Ph. Eur. analytical reagent, Supelco®

Supplier: Merck

Our NH₂, CN- and DIOL-modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An alternative to PEI cellulose, amino-modified NH₂ plates provide weak basic ion exchange characteristics with special selectivity for charged compounds.
