Ordering Information
• inert filter, nominal pore size 1 µm, allows higher flow rates than small pore filters
• for solutions with high loads of particulatematter or for highly viscous solutions (e. g. soil samples, fermentation broths)
• as prefilters for other CHROMAFIL® filters, they prevent plugging of themembrane

CHROMAFIL
Ordering Information
• hydrophilicmembrane
• for polar and nonpolar solutions, water-soluble oligomers and polymers like proteins
• binding capacity for proteins 82 µg/filter
• the PVDF filter with integrated glass fibre prefilter is recommended for filtration of biological samples with high particle loads.
This filter features a high binding capacity for proteins.
• also suited for filtration of polar and nonpolar solutions
