KR2i TFF System®
Tangential Flow Filtration System with Automated Process Controls
and Data Collection Software for R&D Scale Bioprocessing
The new, second generation KR2i TFF System [KrosFlo® Research 2i Tangential Flow Filtration System] is ideal for precise and reproducible control and documentation of Tangential Flow Filtration processes ranging from 1mL to 10 Liters. Highly configurable and versatile, the KR2i utilizes a number user-defined set-points to run complex application processes with numerous built-in safety alarms and stops. The fully integrated system consists of a digital peristaltic pump, man/machine interface with a graphical LCD display, digital pressure monitor, KR2i Easy-Load Pump head, Automatic Backpressure Valve, filter module stand, and KF Comm real-time data collection software. With the pump drive and Easy-Load Pump Head, the KR2i provides consistent and accurate flow rates up to 2.0 LPM. The system can run up to two stackable pump heads for higher flow rates.
