Pore Sizes and Pore Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are usually 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
