Bioprocessing Media

Customizable media and filters for single-use bioprocessing applications.

Robust and versatile media for single-use bioprocessing applications

Bioprocessing media and filters, including spargers, floating filters, wicks, vents and pre-filters for tangential flow filtration can be used in a wide range of applications.

Our POREX® bioprocessing media are:

  • Offered in a wide range of material options, including polyethylene (PE), polypropylene (PP), porous polymeric fiber and polytetrafluorethylene (POREX® Virtek™ PTFE) that provide critical versatility and functionality in single-use bioprocessing applications.
  • Scalable, robust and easy to work with, so that they can be incorporated into various production assembly processes.
