Intensification Leader

Intensification delivers more product faster

XCell ATF Technology helps simplify and intensify upstream processes to deliver more product, faster. Intensified processes achieve higher cell densities, require smaller bioreactors and consume less suite time. Increase throughput, productivity, and capacity in both clinical and commercial manufacturing.

XCellATF delivers 10X VCD and lower COGS

Higher productivity and lower COGs for malaria therapeutic candidate.

  • Can deliver 10X VCD more than 2-week Fed- Batch (350 x 10cells/mL) 
  • 50% decrease in bioreactor time
  • 20-fold increase in yield

How XCell ATF Technology Works

The XCell ATF System is based on award-winning alternating tangential flow (ATF) technology, created by the action of a diaphragm moving upward and downward within a pump head, connected to a filter housing and attached to a bioreactor. Alternating tangential flow is attained by the action of a diaphragm pump.

 Breakthrough technology

Ready to scale from process development to manufacturing​

The XCell ATF System simplifies and fast-tracks upstream intensification development from PD to commercial scale. Intensification increases throughput, accelerates tech transfer and optimizes your process in clinical manufacturing and MSAT while increasing bioreactor productivity and reducing costs in commercial manufacturing. Higher productivity, smaller bioreactors and higher throughput with shorter times to harvest, combine to mitigate facility expansion risks and capital costs. 

 Integrated system

Design simplicity with XCell® Lab System

Designed and engineered as a complete solution, the XCell Lab System integrates a modern controller, XCell ATF Devices, software and flow sensors into a complete solution.

  • Engineering-designed controller promotes increased intensification
  • Configurable set-up delivers high throughput - a single manifold supports up to 8 XCell ATF Devices
  • Software enables precise technical control with a user-friendly interface
  • New XCell ATF 1 Device is fit for low volume intensification ready for scale-up
  • Repligen global technical support ensures successful implementation and scale-up
