KrosFlo® KR2i TFF System

A turnkey benchtop system for 2 ml - 15 L lab-scale process development, the KrosFlo® KR2i TFF System with peristaltic pump is fully integrated and easy to use with walkaway automation.
INTEGRATED
The First Time is the Right Time with
the KrosFlo® KR2i RPM™ System
Finally, a Tangential Flow Filtration (TFF) system that monitors concentration during your UF/DF run. 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, your concentration.
INTEGRATED
Complete, Turnkey TFF System
Fully integrated and ready to use out of the box, the KrosFlo® KR2i enables faster process development facilitating multiple tests/processes, accurate process definition and execution consistency. The system includes precise and reproducible control and documentation of TFF processes with volumes from 2mL to 15L, and filtration areas from 13 cm2 to 5000 cm2.

INTEGRATED
Configurable ProConnex® Flow Paths
ProConnex® 流路是用于切向流过滤的定制化、可配置的完整流路装置,其经工程设计过程而得以强化。该类流路装置可使用中空纤维和/或平板膜包TFF过滤器,在符合ISO指南的ISO 7级洁净室内生产,经预灭菌处理,适配于上游或下游处理应用。

AUTOMATED
Menu-driven Software
KF Comm 2 Software, backward compatible with legacy KrosFlo® KR2i and KrosFlo® KMPi Systems, is conveniently installed on any computer using the Windows Operating System. The software is compatible with Chrome, Mozilla, Firefox and Microsoft Explorer browsers and is always current with automatic software and firmware updates.

AUTOMATED
Monitor and evaluate conductivity, UV and temperature
Konduit is an add-on module ready to use with the KrosFlo® KR2i and KMPi TFF Systems, with the ability to scale from 2mL to 500L process volumes.

READY TO SCALE FAST
Scalable From Lab-scale to Process-scale
The KrosFlo® family of TFF Systems for concentration and diafiltration supports scale up from process development to commercial manufacturing.
KrosFlo® KR2i TFF System
The fully integrated KrosFlo® KR2i TFF System features a digital peristaltic pump, graphical LCD display, digital pressure monitor, KR2i Pump head, automatic backpressure valve, filter module stand, and KF Comm real-time data collection software.
Highly configurable and versatile, the KrosFlo® KR2i utilizes a number user-defined set-points to run complex application processes with numerous built-in safety alarms and stops. The system can run up to two stackable pump heads for higher flow rates.
