Syringe filter, labeled, CHROMAFIL Xtra, PTFE

The hydrophobic PTFE membrane is very resistant towards all kinds of solvents as well as acids and bases. Flushing with alcohol, followed by water, makes the originally hydrophobic membrane more hydrophilic.

CHROMAFIL® Xtra
Labeled for method validation and certification

  • Xtra imprint for the direct identification of the membrane type, diameter and pore size
  • Xtra low bleeding PP housing
  • Xtra color-free plain polypropylene

Polytetrafluoroethylene (PTFE)

  • Hydrophobic membrane
  • For nonpolar liquids and gases
  • Very resistant to all kinds of solvents as well as acids and bases; flushing with alcohol, followed by water, makes the originally hydrophobic membrane more hydrophilic
  • PTFE filters with integrated glass fiber prefilter* (GF / PTFE) are recommended for solutions with a high load of particulate matter or for highly viscous solutions
