terc-Butylmethylether, LiChrosolv® for HPLC, 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.

Silikagel, granulated 1 - 3 mm drying agent, with moisture indicator (orange gel), Supelco®

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.
