Inside the syringe filter polyester (polyethylene terephthalate) is used as membrane material. The hydrophilic multipurpose PET membrane is suitable for polar as well as nonpolar solvents. It is the HPLC filter, especially suited for mixtures of water and organic solvents. It is not cytotoxic, does not inhibit the growth of microorganisms and higher cells. Labeled for method validation and certification. All CHROMAFIL filters are autoclavable (121 °C and 1.1 bar for 30 min)!
