IEX SepFastTM HighRes Plus Media

>>Introduction >>Product Charactistics >>Ordering Info >>How to Order


Q (DEAE, S, CM) SepFast™ HighRes Plus is a group of ion-exchange chromatography media with reduced bead size (20 – 50 μm). They are specially designed for high resolution and high binding capacity purification of biological molecules, where impure components are hard to separate by normal bioprocessing chromatography media.

 The core advantages are:

  • High binding capacity
  • High resolution
  • High sample loading capacity at high flow
  • High productivity

IEX SepFast HighRes Plus is made of a composite of agarose and dextran to give increased dynamic binding capacities. The base matrix is highly cross-linked. The media is very stable to most of the chemical conditions experienced in the bioprocessing industry.
