HPLC columns, Purospher®

Supplier: Merck

Purospher® RP-18 is designed for the separation of problematic basic compounds with simple neutral eluents. In addition Purospher® RP-18 allows the separation of hydrophilic compounds with aqueous mobile phase. Purospher® RP-18 is based upon a high purity, metal-free silica. The multi-step chemical modification and deactivation of the surface, and the polar endcapping, enables a peak-tailing-free elution of basic and chelating compounds. Purospher® RP-18 is not suitable for the separation of acidic compounds. The good chemical stability of Purospher® RP-18 enables the use of mobile phase conditions at pH 8 for a long period of time.

Ion exchangers

Supplier: Merck

In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.

Bottle top filters, VacuCap®

Supplier: Cytiva (Formerly Pall Lab)

Supor® hydrophilic polyethersulphone (PES) membrane; PP housing. VacuCap® filtration device eliminates the need to constantly refill funnel in traditional bottle top filters as it draws directly from the mixing reservoir. The patented small design accepts a variety of collection vessels and reduces laboratory storage space and waste. The Supor® membrane in the VacuCap® 60 and VacuCap® 90 devices provides high flow rates for fast vacuum filtration of 100 ml to 5 litres of aqueous solutions and is available with prefilter to increase throughput of particulate laden solutions.
