Cobetter hydrophobic PTFE membrane filters have the broadest chemical compatibility and inertness and is mainly used for filtration of corrosive chemicals such as strong acids and alkalis, finding applications in numerous industries, including pharmaceutical, biotech, food and beverage, and environmental monitoring.

Features

  • Naturally hydrophobic
  • Biologically and chemically inert
  • Strong chemical compatibility with pH range 1-14

Applications

  • Aerosol sampling
  • Air venting filtration
  • Filtration of strong acids and aggressive solutions
  • HPLC and organic solvent filtration

How to Choose a Membrane Filter

  • Medium, buffer filtration ---------- PES membrane
  • Low protein adsorption filtration --- PVDF membrane
  • Solvent mixture ------------------ Nylon or Hydrophilic PTFE membrane
  • Non-polar (hydrophobic) solution -- Hydrophobic PTFE membrane
  • Polar (hydrophilic) solution -------- Nylon membrane
  • Corrosive solution ---------------- Hydrophobic PTFE membrane
  • Gas filtration --------------------- Hydrophobic PTFE membrane
