Filtering is a required step in processing dissolution samples as it both stops the dissolution of larger particles by separating them from the sample and removes any material that may interfere with the analysis by UV/Vis spectroscopy, HPLC, or UPLC. There are a plethora of materials, shapes, sizes, and porosities available to choose from to ensure that a filter is appropriate for a specific method. In many cases it’s possible to find equivalent filters from other suppliers. However, that equivalence needs to be proven, ideally during the development of the dissolution...
