Ultrafiltration (UF) Columns

Our reusable unit performs a similar function using a centrifuge method and a 13 mm filter diameter to easily collect the concentrated sample solution, the filtrate, or both (13 mm filter sold separately). Consult our UF Flat Sheet Membrane section to select the corresponding membrane for your application.
