CHROMAFIL® PET Hydrophilic multipurpose membrane for polar and 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® PTFE Hydrophobic membrane for nonpolar liquids and gases. Very resistant towards all kinds of solvents as well as acids and bases flushing with alcohol, followed by water, makes theoriginally hydrophobic membrane more hydrophilic.
