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
