Filtration of Aqueous and Organic Solutions

Whether you need to collect, separate or remove contaminants from air or fluid samples prior to downstream analysis, our broad selection of membrane types, pore sizes and surface treatments ensures that we have the right filter for your application. Membrane pore sizes range from 0.025µm to 12µm and net filters (nylon or polypropylene) are available from 11µm to 180µm. Filter discs are available in 13 mm to 293 mm. Non-sterile Millex syringe filters are now available in a new, larger 33 mm housing with Millipore Express PLUS (PES), Durapore (PVDF) and nylon membranes. The larger filter surface area increases flow rates and makes it easier to filter solutions by reducing the pressure required to empty the syringe. Hold-up volume (after air purge) has been reduced to 80µL, a 20% decrease over 25 mm Millex filters.
