ProConnex® TFDF™ Flow Paths

Closed, single-use and complete flow paths optimize TFDF™ (Tangential Flow Depth Filtration) processing with integrated sensors and ready-to-use convenience.

OPTIMIZED FOR TFDF™  processing

The single-use, Gamma-irradiated and closed ProConnex®  TFDF™ Flow Path enables seamless tangential flow depth filtration on a KrosFlo® TFDF™ System. ProConnex® TFDF™ Flow Paths arrive dry, free of sodium hydroxide, glycerin, preservative and ethanol, for a zero flush start state. 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.

ProConnex® TFDF™ Flow Paths are complete assemblies that include:

  • TFDF™ Filter
  • Disposable pump head
  • Integrated sensors
  • Tubing
  • Asceptic connectors

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.
