KrosFlo® TFF Systems

Turnkey systems for tangential flow filtration (TFF), KrosFlo® Systems are compatible with single-use hollow fiber filters and/or flat sheet cassettes, modernizing how UF/DF is performed at every stage from process development to large-scale manufacturing.

KrosFlo® RS TFF Systems

WHEN EVERY DROP COUNTS

Ideal for mRNA and gene therapy solutions, KrosFlo® RS TFF Systems are engineered for maximum recovery. The combination of injection molded tubing, over-molded connections, and valve blocks significantly lowers hold-up volume.

KrosFlo® FS TFF Systems

Fully automate flat sheet TFF processes up to 500 L with configurable hardware components that deliver an unparalleled combination of automation, configurability, simplicity and compliance.

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.

KrosFlo® KMPi TFF System

Fully automate 100 ml - 500 L UF/DF processes using an unparalleled combination of hardware integration with peristaltic pump, configurability and automation through modular, plug-and-play hardware.
