Description
CHROMAFIL® Syringe Filter 25mm GF/PVDF 0.45µm. Combi syringe filters are recommended for solutions with a high load of particulate matter or for highly viscous solutions. These products combine a coarse glass fiber prefilter and a small-pore polyvinylidene difluoride membrane as main filter. The hydrophilic PVDF membrane is for 100 % aqueous samples, water-soluble oligomers and polymers like proteins. All CHROMAFIL filters are autoclavable (121°C and 1.1 bar for 30 min). Recommended Application: HPLC columns packed with particles > 3 µm, GC, SFC; suitable for 100 % aqueous, polar, hydrophilic samples with low particle-load.
