Syringe filtersSyringe filtersSyringe filters (combi), CHROMAFIL GF / PVDF, 25 mm, 1 µm / 0.45 µm



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)!
