Nylon membrane filters can be wet by water easily because they are naturally hydrophilic, providing an high flow rate. It also provides high strength and broad drug compatibility. Cobetter nylon membrane filters do not contain any wetting agents, detergents or surfactants, so they have low extractables, and low protein binding characteristics, often used for filtering aqueous solutions and most organic solutions, especially alkaline solutions and alcohol solutions. It is recommended for filtering DMSO.

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
