Syringe filter (combi), CHROMAFIL Xtra GF / PA, 1 µm / 0.2 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 polyamide membrane as main filter. The rather hydrophilic PA membrane is for filtration of medium polar organic-aqueous liquids. Labeled for method validation and certification. All CHROMAFIL filters are autoclavable (121 °C and 1.1 bar for 30 min)!
