Vivaspin are the optimal solution for any concentration or buffer exchange application covering volumes from 100 µl up to 20 ml for fast and safe sample treatment. The patented vertical membrane design and thin channel filtration chamber minimizes membrane fouling and provides high speed concentrations. Recovery rates of > 90%. Membrane options include a high flux Polyethersulfone (PES); Hydrosart® modified regenerated cellulose membrane (HY) for extremely low protein binding; and Cellulose Triacetate (CtA) with high hydrophilicity and very low non specific binding.Vivaspin 20: Sample concentration from 2 to 20 ml in swing bucket or fixed angle rotors accepting 50 ml centrifuge tubes. Twin vertical membranes for unparalleled filtration speeds. For fast one-step desalting, use Diafiltration cups (VSA005). For highest speeds or for particularly difficult samples, pressurize the device with air or inert gas before centrifuging with pressure cap (VCA200).
