POREX® Dissolution filters are used in conjunction with pharmaceutical tablet and capsule products to help filter contaminates during the dissolution testing process. Heavy metal free POREX Dissolution Filters are available in cannula filters, circulation dissolution filters and filter frit designs in a wide variety of porosities.
Cannula filters, used on the end of a sampling cannula, feature a large surface area and optimized flow rate. Ideal for applications with a high particulate presence, cannula filters are available in 1-70 micron sizes. Circular dissolution filters are used with low-dimension sample probes in applications where it is important to keep the filtration process outside of the vessel. Our circular dissolution filters are available in 10 and 45 micron sizes. Filter tips can be used on sample cannulas with 1/6” diameter in 2–45 micron sizes. Use with low quantities of particulates and flow at the filter bottom.
