Glass Fiber Membrane Filter, 0.7 μm Pore Size

Description

• General description: Millipore fibrous disc filters are available in a wide range of flow rates and throughput capacities. Our Glass Fiber filters are available with or without binder resins and can be sterilized by EO, gamma, or autoclave (121 °C at 1 bar).Glass Fiber Filters with Binder Resin:Millipore filters with binder resin have superior wet strength and are excellent for qualitative analysis and prefiltration, especially for heavily contaminated liquids. They are also widely used for clarification of aqueous solutions.Type AP15Lowest dirt-holding capacityRecommended prefilter for 0.2 to 0.6 μm filtersType AP20Lower retention, higher dirt-holding capacity than AP15 filtersRecommended prefilter for 0.8 to 8.0 μm filtersUse upstream to protect type AP15 filtersType AP25Added thickness yields same retention and greater dirt-holding capacity as AP20Recommended prefilter for 0.9 to 8 μm filters, especially for proteinaceous and heavily contaminated liquidsUse upstream to protect type AP15 filtersGlass Fiber Filters without Binder Resin:The filters without binder resin retain their structural integrity without weight loss when heated up to 500 °C and can therefore be used in gravimetric analysis as well as for the filtration of hot gases.Type APFARetains fine particles with good efficiency, even at high flow ratesRecommended for monitoring wastewater and collecting suspended particles in gases (e.g., fumes from chimneys)Use in biochemical applications (e.g., collection of cells and filtration of protein or nucleic acid precipitates)Type APFBHigher mechanical strength when wet and greater loading capacity than type APFA filtersUse for liquid clarification, quantification of solids in suspensions of fine particles, and scintillation countingType APFCGreater retention, especially for fine particulate and microorganism removal than type APFA filtersUse for determining total suspended solids in drinking waterUse for filtering proteins or nucleic acid TCA precipitates and for collecting cells and microorganismsType APFDThick filter with high flow and low retentionUse for clarifying suspensions containing particulates greater than 1.0 μmType APFFUse for filtering extremely fine precipitates such as protein, nucleic acids, or serum precipitatesRecommended for USEPA method 1311 for TCLP analysisType AP40Recommended for Standard Methods Total Suspended Solids 2540DRecommended for USEPA method 1311 for TCLP analysisMaintains structural integrity without weight loss when ignited to 550 °C (1022 °F) after sample filtrationRecommended for determining volatile suspended matter in wastewater and industrial effluents
