Syringe filtersSyringe filtersSyringe filters, labeled, CHROMAFIL Xtra PES, 25 mm, 5 µm


Inside the syringe filter polyethersulfone is used as membrane material. The hydrophilic PES membrane is suitable for aqueous and slightly organic liquids. This filter shows a good stability against acids and bases as well as a very low adsorption for pharmaceuticals and proteins. Labeled for method validation and certification. All CHROMAFIL filters are autoclavable (121 °C and 1.1 bar for 30 min)!
