  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

为确保从1 L到2000 L的线性规模放大,组件内纤维管数和管长度随处理量而增加。管长度可从20 cm增加至108 cm。过滤器的有效长度可能低于过滤器的物理长度。单根组件内的管数可从1根增加至40根。

Espresso depth filtration

Replace sluggish messy depth filtration with combined tangential flow and depth filtration. No need to load multiple filters or hunt for parts. At 1L through 2000L, connect one fully integrated filter module and go -- at flux speeds up to 1950 LMH.
