With sizes ranging up to 5000L, Repligen KrosFlo® KTF Systems for tangential flow filtration (TFF) set the standard for configurable, premium quality systems for modern bioprocessing.
One integrated system, configurable design
KrosFlo® KTF Pilot and Process Systems overcome many challenges in single-use bioprocessing today.
Built on the principle of flexibility, one system can be used from small to large scale, using either hollow fiber filters or flat sheet cassettes. One system can be used upstream or downstream supporting multiple unit operations.

Configurable, single-use TFF systems for rapid bioprocessing
See how Repligen systems for tangential flow filtration combine unparalleled configurability with premium quality manufacturing. System designs maximize scalability from small to large volumes, flexibility between hollow fiber and flat sheet filter formats, and ability to use the same system in different unit operations while deploying ready-to-use application-specific flow path assemblies. To ensure success, a team of sales specialists and applications experts helps support rapid start-up and robust operation in cGMP processes.

CONFIGURABLE ProConnex® FLOW PATHS
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.
ProConnex® Configurator
In minutes, using an online drag and drop configurator and with customer input, Repligen representatives can configure a ProConnex® Flow Path specific to a process application in real-time. The output of the ProConnex® Configurator are 3D engineering drawings and a preliminary quote, which greatly expedite the approval, production and delivery of the ProConnex® Flow Path.
