Fit-for-purpose brand-agnostic design and open architecture ensures a system that meets your exact requirements

Agilitech single-use tangential flow filtration (TFF) systems provide the flexibility and agility to perform purification operations upon delivery, while every part of the TFF system features best-in-class components to optimize performance.

Designed to streamline your bioprocess, increase sample recovery, and reduce the cost of consumables

A magnetically levitated pump combined with a cubical mixing bag with magnetic mixer limits shear on the product throughout the filtration process, maximizing yield at every TFF step. The pump also maintains proper transmembrane pressure by providing a near pulsation-free fluid dynamic and meeting flow and pressure requirements; this is crucial to optimizing filter performance throughout the TFF process. Combined with an air modulated diaphragm pressure control valve, retentate pressure reaches set point almost instantly to achieve the desired TMP. These design features work to eliminate pump pulsations and pinching control valves that lead to more erratic pressure control.

Designed for temperature control of solutions from 2 – 50°C, you can run processes at higher concentrations and with more viscous solutions. The system also maxmizes product recovery in the recirculation bag. Users simply disconnect the tubing from the TFF skid and move the recirculation bag to the next step for further processing. This results in fewer consumables and reduced cost, while eliminating project delays due to supply chain issues with consumables.

Maximum flexibility

  • Integrates virtually any brand hollow fiber and flat sheet style filters
  • Custom single-use assembly accommodates Sartorius, Millipore, Pall, and other preferred filter brands
  • Both recirculation vessel weight control and permeate flow control available
  • Diafiltration mode available (with buffer feed)

Single-use technology ensures a safe and sterile process

  • Fully sterilized single-use tubing sets, complete with integrated sensors, minimize risk of contamination
  • Sterile-to-sterile connections for inlets/outlets reduce contamination risks
  • Highest quality components; USP <88> Class VI certified single-piece tubing sets ensure sterility throughout use*

*Excludes flat sheet filter connections that are made at the time of use.

State-of-the-art automation and control—your way

We can deliver the TFF skid with your preferred automation and control system whether that’s DeltaV, Rockwell Automation, Inductive Automation Ignition Software, Wonderware, or other platform. Our seasoned engineers have decades of experience across a wide range of platforms. Regardless of the platform you choose, the user experience is the same due to the ISA-88 batch-compliant structure that is used to create the building blocks of the automation.

Easy-to-use, intuitive control panel

Our automation engineers have listened to end users and applied years of bioprocess experience to optimize the user interface of the TFF system control panel. We have identified the functions and data that operators need to access most often, and the user interface brings these functions and data to the top layer of the screen—no more endless clicking or digging to access data.
