These point-of-use filters meet small to mid-volume photochemical filtration needs for positive developer and DI water applications. Both Optimizer® DEV filters (for developer applications) and Optimizer® DI filters (for DI water applications) require no pre-wetting, so the filters function immediately after installation. The design also limits the handling of hazardous chemicals during the installation and promotes a healthier workplace. Do not use either filter with aromatic hydrocarbons.

Pierce strong cation exchange and strong anion exchange spin columns use membrane-adsorption as the chromatographic method of choice to fractionate proteins based on their charge differences. The column matrix has a highly porous structure, with pores larger than 3000 nm, giving proteins ready accessibility to the membrane's charged ligands. These adsorptive membranes maintain high efficiencies at high flow rates and during fractionation of large biomolecules with small diffusivities.
