  INNOVATION BREAKTHROUGH

Novel TFDF® Filter 

The thick-walled 2 - 5 µM tubular filter captures cells and cell debris with reduced fouling and negligible product retention. The feed stream enters the bottom port. The retentate travels through the lumen and exits at the top of the tube. The permeate exits the enclosure through the lower permeate port.​solution. The combination of tangential flow and depth filtration in one filter produces a high-flux, high-capacity solution.  h

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.

READY TO SCALE FAST

Maintain processes while scaling to production

The KrosFlo® TFDF® System delivers application-specific process control logic for optimal TFDF process performance. Systems scale from 1 L to 2000 L in a small footprint of 1 m2 for both pilot (31 inch x 42 inch) and process (37 inch x 42 inch) systems.

READY TO SCALE FAST

Capacity increases with tube number and length

1~2000 Lのリニアスケーラビリティを実現するには、エンクロージャーごとのチューブの長さとチューブの数を増やします。チューブ長さは20 cmから108 cmまで増やせます。フィルターの有効長さは、フィルターの物理的長さより短くなることがあります。エンクロージャーごとのチューブ数は、1から40まで増やせます。
