Thin channel, crossflow filter units with 50cm² / 200cm² filter areas for capacities between 100ml / 500ml and 5L. This system provides high crossflow rates at minimum pumping pressure and does not require additional fittings for scale-up. VivaFlow 50 is easy to operate with a flow restrictor and, optionally, a pressure indicator. Modular construction with luer connections allows interlocking of units in series for easy scale-up. Recovery rates are maximised due to optimised recirculation volume and by use of low adsorption materials. Disposable.
For greater volumes, VivaFlow 200 is available with a filter area of 200cm² and includes pressure indicator, flow restrictor, filtrate tubing and connectors.
