Detailed information
-
◎Water system type (4A・13A・25A・13S) - Composed of a hydrophilic membrane and polypropylene housing (blue color). - Ideal for pre-treatment of samples for liquid chromatography analysis targeting aqueous and alcohol solutions, as well as protein analysis. - Best suited for sterilization and particle removal. - Acetonitrile aqueous solutions can be used up to 30%. - The 13S type integrates the chromatographic disk and syringe into one unit.
-
◎Non-aqueous type (4N, 13N, 25N) - Composed of a PTFE membrane and polypropylene housing (translucent color). - Excellent solvent and chemical resistance. - Ideal for the pretreatment of samples for trace analysis involving solvents, strong acids, strong alkalis, etc. - Also excellent as an air vent filter.
-
◎ Compatible with both aqueous and non-aqueous systems (4P, 13P, 25P) - Acetonitrile aqueous solution can be used up to 100%. - Can be used as a type compatible with both aqueous and non-aqueous systems. Filter: Hydrophilic PTFE Housing: Polypropylene - Excellent solvent and chemical resistance. - Can be sterilized by autoclaving.
-
◎ Ion chromatography type (4AI, 13AI, 25AI) - Composed of a hydrophilic membrane treated with deionized water and a polypropylene housing. (Green color) - Ideal for the pre-treatment of ion chromatography analysis samples. - Packaged in sets of 10 for clean storage.
