ZERO MANUAL INTERVENTION

Automate from sanitization to recovery 

Eliminate batch variation with end-to-end automation

READY TO SCALE FAST

For effortless scaling from 1/4" to 1"

Maintain processes while scaling to production
When every drop counts

Minimize hold-up volume with innovative valve block technology

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.

When every drop counts

Intelligent mixing even at the lowest working volume

Innovative tulip tank technology delivers hold-up volumes as low as 1.5L with active mixing.

As fluid levels drop, the dual impellers independently adjust speed to reduce harmful surface interaction while automated valves adapt retentate flow to avoid damage upon entering the tank.​

ZERO MANUAL INTERVENTION

Eliminate batch variation with end-to-end automation

Completely automate processes from start to finish without intervention.

Traditional single-use systems require manual manipulation due to the limited number of controlled valves. Additional controlled valves throughout the flowpath allow complete automation of processes.

Industrial grade components and extended automation allow for confident process scaling. With the same software, hardware, controls and cGMP compliance built into every system, process change challenges in scale-up are removed.

KrosFlo® RS TFF Systems

KrosFlo® RS Single-use Tangential Flow Filtration (TFF) Systems incorporate the most advanced engineering principles to achieve unprecedented automation, hold-up volume and process control. The unique tulip tank continuously measures sample volume and then adjusts dual impeller speeds and retentate routing to nearly eliminate foaming. Conceptualized as a platform, rather than a single system, a single architectural approachenables effortless scale-up from 1/4" to 1".
