Chromatography Frits, Media Support, and Filters

In addition to decades of experience engineering customizable chromatography frits for global customers, POREX® porous polymer materials can create a single frit powerful enough to replace the two support frits and the loose beads in the stationary phase. By modifying one frit with your choice of surface treatments and functionalized resins, separation device manufacturers can increase their operational efficiency and get more accurate results. When you collaborate with Porex, the only limitation is your imagination

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.

Dissolution Filters

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.

SPE Frits & High Throughput Automation Filters

Porex offers a variety of PE, PP, and porous PTFE chromatography filters — commonly known as chromatography 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.

Protein Precipitation Media

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.
