Pore Sizes and Volumes The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm, respectively.
For organic-solvent- based samples, especially for aggressive solvents, polypropylene (PP) or polytetrafluoroethylene (PTFE) filters should be used. For mixtures of organic/aqueous samples, PTFE, PP, nylon (polyacrylamide, PA), RC, and PES filters can be used according to solvent composition.
Cytiva Solvent IFD is a high-flow HPLC in-line filter/degasser, designed to simultaneously filter and degas organically based HPLC mobile phases. Faster than traditional mobile phase preparation Chemically resistant polypropylene merane and housing, built to filter solvent mobile phases…
Some merane materials are also available sterile. Merane filters are typically used in both liquid and air filtration. They offer accurately controlled pore size distribution with high strength and flexibility, and are suitable for a wide range of appliions such as basic research, environmental testing and pharmaceutical as well as food and beverage industries.
