CHROMAFIL® Syringe Filters – Polyester (PET)

  • Hydrophilic multipurpose membrane
  • For polar as well as nonpolar solvents
  • This filter, primarily used for HPLC, is especially suited for mixtures of water and organic solvents for TOC/DOC determination
  • This filter is not cytotoxic and does not inhibit the growth of microorganisms and other cell types
  • 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.
