Dissolution Filters

Protect samples with affinity filters and supports POREX ® affinity filters and supports are an innovative range of advanced porous materials that enhance functionality through surface modification or sorbent addition. Designed to capture, clean-up, desalt and purify peptides, proteins and oligonucleotides. POREX affinity filters and supports help optimize flow and retention variables and can be used in pipette tips, multi-well plates, spin down and gravity flow centrifuge columns. Our Porex materials: Aid in the optimization of flow and the retention variables through surface modification and sorbent addition/blending. Help facilitate high resolution with high flow velocity. Have multiple configuration designs for applications such as pipette tips, 48- and 96- well plates, spin columns and gravity flow columns. Offer versatile options including discs, sheets with Controlled Pore Glass (CPG), reverse phase (C8, C18, other), anionic, cationic, all in a homogenous porous...

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...
