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.


XCell®ATF delivers 10X VCD and lower COGS


  • 10X VCD more than 2-week Fed- Batch (350 x 10cells/mL) 
  • バイオリアクターの時間を50%短縮
  • 収量が20倍に増加

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.

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.
