Syringe filtersSyringe filtersSyringe filters, labeled, CHROMAFIL Xtra PES, 25 mm, 0.45 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)!
