Single-use fully integrated benchtop TFF system for use in lab scale process development ranging from 2mL - 15L. Compatible with hollow fiber or flat sheet filters, this system offers many user-defined set-point controls so you can run complex applications in fully-automated modes. KrosFlo KR2i TFF systems achieve an unparalleled combination of configurability and user-simplicity through modular, plug-and-play hardware. All components, either directly or indirectly, connect to the main pump, which then communicates with the KF Comm 2 software for control and monitoring. The Fully integrated KrosFlo KR2i TFF System features a digital peristaltic pump, graphical LCD display, digital pressure monitor, KR2i Pump head, automatic back pressure valve, filter module stand, and KF Comm real-time data collection software.
