CHROMAFIL® Syringe Filters, Polyester (PET)



  • Hydrophilic multipurpose membrane
  • For polar as well as nonpolar solvents
    The HPLC filter, especially suited for mixtures of water and organic solvents for TOC/DOC determination not cytotoxic, does not inhibit the growth of microorganisms and higher cells.
  • Polyester filter with integrated glass fibre prefilter (GF/PET): recommended for solutions with a high load of particulate matter or for highly viscous solutions

CHROMAFIL® Disposable Filters

This table lists the chemical compatibility of our CHROMAFIL® materials. The chemical compatibility depends on several parameters such as time, pressure and concentration. In most cases, CHROMAFIL® filters will have only short contact with a solvent. In these cases they may be used despite limited compatibility. For example, a PTFE filter with PP housing does not liberate any UV-detectable substances during filtration of 5 ml THF, although PP shows only limited resistance towards THF.
