Additional Information
Polytetrafluoroethylene (PTFE) - Hydrophilic or Hydrophobic
- PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases.
- Very resistant to solvents as well as acids or bases.
- Can be made more hydrophilic by flushing with alcohol, followed by water
- Used for filtering and de-gassing chromatography solvents
- Permits optimal utilization of small sample volumes
- Excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials
- Moisture barrier for venting applications and vacuum pump line protection
- Ideal for aerosol sampling
- Filter viscous organic based HPLC samples
- After pre-wetting with alcohol, may be used for fine particle removal of aqueous and mild organic solutions in Ion Chromatography
