Satisfy most applications needs in the biopharmaceutical market where high concentrations of colloidal contaminant dictate the need for high surface area depth media with a positive charge.
Millistak+® clarification/prefiltration stacked disc filters have been specifically developed to meet the critical needs of the pharmaceutical and biotech industries, incorporating a broad range of controlled porosity graded density depth media
Available media series satisfy most applications needs in the biopharmaceutical market where high concentrations of colloidal contaminant dictate the need for high surface area depth media with a positive charge. Within the CE series, a variety of grades enable the user to choose the filter best suited to his application. Media grades are differentiated by flow characteristics rather than by micron ratings. Nominal retention guidelines are provided but trials in customer fluids are recommended for selection of the optimum filter based on processing conditions. The CE series is suitable for coarse filtration in the 1 to 30 micron range
Monitored gradient density matrix assures consistent filtration performance
Filter matrix exhibits positive charge properties to enhance filtration performance
Broad range of media grades to assure optimal performance
Media available to fit virtually any filter press
Typical extractable levels have been determined by laboratory analysis utilizing a dynamic flow rinse procedure. Inorganic extractables are quantified by atomic absorption analytical techniques. The results are expressed as milligram per ft2 of media subsequent to the standard recommended flush of 100 L/m2 (10 L/ft2) of media surface area
