CHROMAFIL PET
• hydrophilicmultipurposemembrane
• 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 particulatematter
or for highly viscous solutions

CHROMAFIL Sterile filters
• hydrophilicmembrane
• for filtration of water-soluble oligomers and polymers, especially suited for biological macromolecules
• very high shape stability in aqueous solutions
• extremely low binding capacity for proteins (21 µg/filter)
• also available in a sterile package (S) for filtration under sterile conditions (each filter individually sealed)
