Vivaflow 50 and Vivaflow 200 are ready-to-use crossflow units for fast and gentle concentration of biomolecules at laboratory scale. High recovery rates are achieved by using low-adsorbing membranes. For increased capacity, up to 6 Vivaflow 50 or 2 Vivaflow 200 units can be run in parallel. Membrane: regenerated cellulose, Hydrosart® or polyethersulfone. - Sample volume: 500 ml to 5 l.
