ambr® crossflow is a benchtop crossflow system optimised for ultrafiltration and diafiltration applications. It is a small scale screening system with a minimum recirculation volume of 5 mL and a dedicated new range of ambr® CF filter cassettes with 10 cm² membrane area. Parallel operation is achieved with 4 independent crossflow channels per module, with up to 4 modules managed by one control station. This means ambr® crossflow is capable of performing membrane screenings with up to 16 ambr® CF filters simultaneously.
