KrosFlo® KMPi TFF System

Designed for pilot-scale purification using tangential flow filtration (TFF), the KrosFlo® KMPi System delivers precise process controls and accurate data collection.
       •  100mL - 500L volume
       •  0.049 m2 - 5.1 m2 filtration area

TFF for Pilot scale purification

 

Designed for 100mL - 500L purification applications, the KrosFlo® KMPi TFF System from Repligen is designed for robust pilot-scale downstream ultrafiltration and microfiltration.

Fully integrated and ready to use out of the box, the KMPi provides consistent and accurate flow rates with a range of 0.01 to 13.0 LPM. 

How hollow fiber TFF works

KrosFlo® KMPi TFF SYSTEM 

The fully integrated KrosFlo® KMPi TFF System consists of a digital peristaltic pump, multi-language interface with a graphical LCD display digital pressure monitor for automated alarm and shut-off controls, KMPi Pump head, scale for automated alarms and shut-off controls, Automatic Backpressure Valve, module stand, and proprietary KF Comm Software. The KrosFlo® KMPi provides consistent and accurate flow rates with a range of 0.01 to 13.0 LPM.

Automatic Back pressure control Valve

Unique to Repligen, the KrosFlo® Back Pressure Control Valve is key to integrating and automating the TFF process, reducing operator process management time and TFF processing time.

  • Automatically adjusts tubing pinch distance according to user-defined set-points for inlet, retentate, permeate or transmembrane pressures (TMP) when attached to the ProConnex® flow path
  • Maintains a uniform TMP throughout the process run, decreasing membrane fouling
  • Controls the permeate pressure and flow during microfiltration applications
  • Releases and tightens the pinch valve as solution viscosity increases or decreases during a process
  • Can be set to start pinching from the open, middle, or closed position
  • Compatible with tubing sizes 13, 14, 16, 25, HP15, 17, HP24, 18, HP35, 36, and HP36

CONFIGURABLE Pro-Connex® FLOW PATH

Enhanced through an engineering design process, ProConnex® Flow Paths are customized, configurable and complete assemblies for tangential flow filtration.  Designed for use with hollow fiber and/or flat sheet TFF systems, the assemblies are sterile, fit for upstream or downstream processing and manufactured in compliance with ISO guidelines in an ISO 7 clean room.
