Labscale TFF-System

It is possible to reuse both ultrafiltration and microporous membranes used in Millipore Tangential flow systems (Miniplate, Prep Scale etc.). The number of uses for any given set of membranes is directly related to the effectiveness of the cleaning and storage protocols used. Please refer to the TFF Maintenance Guides for suggested cleaning and storage procedures.
