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.
Because of their low inherent levels of extractables, nylon membrane syringe filters are commonly used to filter samples that are intended for HPLC analysis. Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents.
