DNA & RNA Purification and Extraction Media

Cost-effective solutions for rapid nucleic acid purification and extraction

High recovery of filtrates and analytes with no cross-contamination between wells

Alternatives to glass fiber engineered specifically for each customer, Porex advanced porous solutions remove particulates quickly and efficiently in a broad range of DNA/RNA purification and extraction applications, including spin columns, gel filtration and deep well filtration. 

Spin Column Media & Support

POREX® offers a variety of filters for DNA/RNA extraction and purification techniques in a range of porous materials including PE, PP, POREX Virtek® PTFE and other porous media.

Our spin column media and support:

  • Increase binding capacity and recovery of nucleic acids–Functionalized membranes offer surface modification or sorbent addition.
  • Deliver a high recovery of nucleic acids–Purity of filter media combined with inert support media hold medium in place, helping bind nucleic acids to the media.
  • Are purity tested by independent laboratories – CERTIFIED PURE POREX® materials ensure performance, accuracy and reproducibility.

Gel Filtration Media Support

  • Gel filtration media are used for the analysis of molecular size, separations of components in the mixture, salt removal or buffer exchange for a preparation of macromolecules. Porex provides media support that holds the functionalized stationary phase in place, ensuring repeatable column performance. POREX® gel filtration media:
    • Deliver quick and efficient desalting, buffer exchange and removal of low molecular weight compounds through an inert and functionalized porous membrane.
    • Provide enhanced functionality through surface modification or sorbent additions such as CPG, carbon, C8 or C18.
    • Are design optimized for purification and desalting of oligonucleotides, proteins, small molecules from nucleic acids, etc.
    • Are tested by independent laboratories – CERTIFIED PURE POREX® materials ensure performance, accuracy and reproducibility.

Deep Well Plate Filter Media

  • Used for high recovery of filtrates and particulate retentates, POREX® deep well filter media are designed for high-throughput sample processing. Our POREX deep well filter plate media features:
    • High sample recovery for many processing techniques including filtration, vacuum filtration, centrifugation or other positive pressure techniques.
    • Minimal contamination–Porous material structure prevents cross talk between adjacent well walls.
    • Proprietary surface modification – Materials allow multiple functionalities or sorbent addition, including CPG, carbon C18 or C8, and media is suitable for vacuum filtration, centrifugation or other positive
