KrosFlo® KTF TFF Systems

Uniquely combining simplicity and configurability, Repligen KrosFlo® KTF Systems perform hollow fiber TFF to support multiple scales, unit operations, and solutions.
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.

Configurable
Flexible across multiple parameters
KrosFlo® KTF Systems are configurable across multiple parameters, such as volume, application, and filter type. Multiple pumps of different sizes augment volume capability. Multiple pump types at different positions expand application and filter type support.

Volume Flexibility
- Configure for a wide range of batch sizes
- Fully compatible with ProConnex® TFF Flow Paths
- Line 1 supports up to 2500 L (KrosFlo® Max X06 Filter)
- Line 2 supports up to 1000 L (KrosFlo® K06 Filters)

Application Flexibility
- Configure for multiple applications
- iFIX software programmed for TFDF® applications
- Fully compatible with ProConnex® TFDF® Flow Paths
- Line 1 supports UF/DF (1500 cm2)
- Line 2 supports UF/DF (6000 cm2)

Configurable
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.
integrated
Integrated to support multiple scales and applications
The fully integrated KrosFlo® KTF Systems consist of hardware, software and flow path components. Key hardware components include a digital peristaltic pump, auxiliary pumps and an automatic back pressure valve. Different combinations support multiple scales, unit operations and applications to maximize resource utilization.
