Description

Features

  • Filter insertion in clean room by manual as well as fully automated means.
  • Molding in place, over molding and support structure molding of fragile media.
  • Ultrasonic welding of barrel structure for increased leak / burst resistance.
  • Multi-process mold extensions for inclusion of single or multi-level prefiltration media.
  • Digital variable print capabilities along arc on barrel face for identification purposes.
  • Blister packing for EO and gamma sterilization.
  • Pure virgin PP, verified by HPLC against U/L extractables.

Polytetrafluoroethylene (PTFE) - Hydrophilic or Hydrophobic

  • PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases.
  • Very resistant to solvents as well as acids or bases.
  • Can be made more hydrophilic by flushing with alcohol, followed by water
  • Used for filtering and de-gassing chromatography solvents
  • Permits optimal utilization of small sample volumes
  • Excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials
  • Moisture barrier for venting applications and vacuum pump line protection
  • Ideal for aerosol sampling
  • Filter viscous organic based HPLC samples
  • Glass microfiber prefilter raises absorption capacity and loading
  • After pre-wetting with alcohol, may be used for fine particle removal of aqueous and mild organic solutions in Ion Chromatography
