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
INNOVATION BREAKTHROUGH
Synergistic Benefits
- Low concentration polarization minimizes fouling
- Short, highly inter-connected paths do not retain product
- Small footprint
- 2-5 micron pore size for large biomolecules

READY TO SCALE FAST
Capacity increases with tube number and length
To ensure linear scalability from 1 to 2000 L, the tube length and the number of tubes per enclosure increases. Tube length increases from 20 cm to 108 cm. The effective length of the filter may be less than the physical length of the filter. The number of tubes increases from 1 - 40 per enclosure.
