ÄKTA readyflux

Great filtration capabilities in a compact design.


Bring confidence to filtration


Reliable automation and sensors enable efficient process control.


Flexible choice of filters and accessories provide versatile system use.



Easy, software-guided installation of the single-use flow path that supports high productivity.


Compact design for efficient use of costly clean room areas.

Fitted to your needs

ÄKTA readyflux is an automated single-use filtration system for pilot and small-scale manufacturing. The system is intended for crossflow (also called tangential flow) filtration applications in both upstream and downstream workflows.

Reliable operations

A high level of automation reduces operator dependency and adds consistency to your process. Should anything need your attention, such as end of process, drop in flux, or high pressure, you will be notified by a system alert.

Process data is securely stored for later analysis and evaluation, and for generation of a final batch report.


Designed with user in focus

Easy method preparation and flexible automation methods for both upstream or downstream operations require no programming expertise. Preprocess, process, and post-process steps are included in the methods and are supported by the pre-programmed method phases.

Installation of the flow path is quick and reliably guided by the software-aided installation wizard.

Designed with user in focus

Small footprint, wide application range

The compact system design allows for low minimum recirculation volume, for high concentration factors and product recovery.

The system can be used with both filter cassettes and hollow fiber filter cartridges. Hollow fiber filter cartridges are connected using an adjustable filter holder. The Fluxkart fits cassette holders of choice.

The system supports the use of a wide range of single-use bags. While the Bagkart fits 2D bags, 3D bags can be used with the XDUO or XDM mixers.

Single-use Flow Kits for your convenience

The Flow Kits are supplied gamma irradiated and includes single-use flow path, pumps, and sensors for pressure, conductivity, temperature, flow, and pH (depending on choice of Flow Kit).

The Flow Kits are available with Tri‑Clamp™ connectors or with ReadyMate connectors for aseptic connection.  

Flow Kits

Single-use Flow kits

Flexible filter use

For closed system operations, ReadyToProcess hollow fiber filters, delivered presterilized and ready for use, are recommended. ReadyMate connectors enable quick and easy aseptic connection of the filter to the system. To increase operator safety, minimize cross-contamination risk, and address bioburden challenges, the filter is disposed together with the flow path after use.

Most commercially available filter cassettes can be used with the system.
