Affinity Filters and Supports

Filter out contaminants during the dissolution testing process POREX ® Dissolution Filters are used in conjunction with pharmaceutical tablet and capsule products to help filter contaminates during the dissolution testing process. Heavy metal free POREX ® Dissolution Filters are available in cannula, circular/disk and filter frit designs in a wide variety of porosities and: Meet U.S. Pharmacopeia Standards for elemental impurities Can be used with molecular diagnostics, clinical IVD, infectious diseases and research applications. Will withstand automated assembly equipment and resist breakage due to strong, durable and lightweight construction. Are designed with chemically-resistant media which will tolerate most acids and bases. Offer instant pore size identification with color-coded resins. Cannula Filters POREX ® Cannula Filters are used on the end of a sampling cannula and feature a large surface area and optimized flow rate for an ideal choice in applications with a high...

Remove contaminants from protein samples without plugging or breakthrough Protein precipitation is widely used in downstream processing of biological products to concentrate proteins and purify them from various contaminants. POREX® Precipitation Membranes aid in the removal of contaminating lipids, salts and proteins from samples prior to LC-MS/MS without plugging or breakthrough. Designed to retain acetonitrile, methanol and other organic solvents our protein precipitation media solutions: Retain acetonitrile, methanol and other organic solvents. Provide reproducible and consistent results and are chemically inert, hydrophobic, oleophobic, while containing no leachables Increase efficiency through elimination of time-consuming centrifugation and transfer steps. Are independently tested for solvent leakage, nonspecific binding, flow rates and well blockage by LC-MS/MS. Are a PE based solvent support media solution - designed to retain low surface tension organic solvents for...

High-performing frits for the most challenging chromatography applications POREX offers a variety of PE, PP and porous PTFE filters — commonly known as frits, for use in commercially available SPE columns, cartridges or multi-well SPE plates to facilitate column concentration to a vacuum manifold, needle or collection vessel. Hydrophilic, oleophobic, blended-resin, and functionalized materials are also available for use in the most challenging chromatography applications. Porex frits and filters offer: Controlled flow for optimized reaction time (kinetic control). Superior resin support due to narrow pore size distribution. Cleanliness and high purity with very low levels of extractables, leachables, and particle shedding. Custom designs in various disc, spherical, and other geometries to help ensure a tight material seal, optimized assembly operation, and no resin by pass. Fast & easy assembly in mass production - rigid structure facilitates manufacturing...
