Selection Guide – How to Choose

By Application

  • Routine → Disposable PTFE
  • Analytical (HPLC / GC) → Standard PTFE
  • Sterile / pharma → Sterile PTFE

By Sample Type

  • Organic solvents → Hydrophobic PTFE
  • Gas / air → Hydrophobic PTFE
  • Strong acids / bases → PTFE

Aqueous solutions require pre-wetting or hydrophilic PTFE.

By Pore Size

  • 0.45 μm → General filtration
  • 0.22 μm → Fine filtration / bacteria removal
  • 1.0 μm → Gas sterilization

Gas Filtration & Venting

Hydrophobic PTFE syringe filters are widely used in gas filtration due to their water-repellent membrane structure.

Key Benefits:

  • Prevents moisture ingress
  • Maintains sterile airflow
  • Ideal for fermentation venting
  • Protects tanks and systems
  • Suitable for air, steam, and gas filtration
