Syringe filters (combi), CHROMAFIL Xtra GF / PTFE, 25 mm, 1 µm / 0.45 µm 11-PSN(B)-ST1 GE Instruments Sievers 900Combi 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 polytetrafluoroethylene membrane as main filter. The hydrophobic PTFE membrane is very resistant towards all kinds of solvents as well as acids and bases. Flushing with alcohol, followed by water, makes the originally hydrophobic membrane more hydrophilic.
