Express-Ion® media are matrices whose flow characteristics have been greatly improved. The manufacturing process has been optimized so that the matrix retains its inherent property of fast kinetics of adsorption and desorption. Media characteristics are; EXPRESS-ION D: A weak anion exchange cellulose substituted with diethylaminoethyl (DEAE) groups and recommended for separations between pH 2 and pH 9.

Whatman 3-Piece filtering funnels are quickly dismantled and ready for the insertion of new filters. The glass sealing flanges of the funnel and reservoir are ground flat to ensure a good filter seal. All retained solids are deposited within the filter circle. The edge clamping prevents peripheral loss and possible passage of solution around, rather than through, the filter circle. The parts can be quickly and efficiently cleaned because of the simplicity of design. For quick and easy filtration, Whatman 3-Piece filter funnels are available with a choice of three plates.
