HPLC Mobile Phase Filtration Membranes

Membranes Designed for the Stringent
Requirements of Mobile Phase Filtration

  • Membranes are identical in composition and quality to those used in Pall’s HPLC-certified Acrodisc® syringe filters
  • HPLC certification assures that the filters will not add artifacts to your analysis
  • GH Polypro membrane is the best choice for filtering mobile phases
  • PTFE membrane provides the ultimate in chemical compatibility for filtering harsh chemicals and HPLC mobile phases
