PTFE membrane 25mm or 37mm is suitable for air monitoring and sampling in aggressive environments, gravimetric sampling, and filtration of gas and/or organic solvents. Its structural strength and ease of handling make it a reliable choice for various applications. The low chemical extractable background and hydrophobic properties of the PTFE membrane also make it ideal for sensitive and interference-free analysis.


  • Structural strength and ease of handling from laminating 2 layers of PTFE together
  • Chemically resistant properties of PTFE
  • Low chemical extractable backgrounds
  • Hydrophobic
  • Compatible with both gas and liquid sampling
  • A suitable replacement for the discontinued Zefluor membrane
