Robust Processing

Ultrafiltration and diafiltration (UF/DF) processing for batch volumes ranging 2mL to 15L.

使いやすい

Plug and play configurability to add and remove components as needed with minimal effort.

Compatible with flat sheet cassettes and hollow fiber filters.

Walk-away automation

13 automated process control modes with the Automatic Back Pressure Valve (ABV) and intuitive software platform.

Off-the-shelf flow paths

Gamma irradiated, single-use, ProConnex® flow paths for enhanced reproducibility, time savings and sterility.

Modularity Made Easy with Plug-and-Play Configurability

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.

KrosFlo KR2i automatic back pressure valve (ABV) in open and closed position.

Walk-away automation for your lab

The days of manually adjusting screw clamps are over. A Repligen-exclusive technology, the Automatic Back Pressure (ABV) Valve adds transmembrane pressure (TMP) control to every TFF process, reducing operator hands-on-time, data logging and continuous monitoring while improving process reproducibility. 

  • Automatically adjust tubing pinch distance according to user-defined set-points
  • Maintain uniform TMP throughout process run, decreasing membrane fouling
  • 対応チューブサイズ: 13、14、16、25、HP15、17、HPP24、18、HP35、36、HP36

インラインタンパク質濃度管理が可能なTFF

No longer are you dependent solely on mass inputs and off-line fixed-pathlength UV-Vis spectrophotometers. Now, you can measure what truly matters in real-time with the KrosFlo® KR2i RPM™ System. Monitor concentration in real time during your UF/DF run and control your process.
