By offering various lengths, membrane filtration areas, and module diameters, Cobetter hollow fiber modules can facilitate a smooth and predictable scale-up from laboratory to pilot-scale and eventually manufacturing-scale. Available from Mini, Minilab, Lab, Pilot, Pilot+, Process and Max.

Cobetter hollow fiber modules are made of modified polyethersulfone membranes(m-PES), which have high flow flux and low protein binding. They are easy to install, clean and sanitize, which are widely used in cell harvest, clarification, perfusion, diafiltration and concentration in upstream and downstream bioprocessing.

Compared with TFF Cassettes' tortuous and complicated flow path, hollow fiber filtration has a linear flow path which creates a smooth flow for more gentle separation.

Effective Length and Scale-Up

The process scale-up feature of hollow fibers is that: direct process scale-up can be carried out as long as the effective length is kept the same.

On the opposite, due to the significant pressure drop difference between inlet and outlet existed in different lengths, the internal pressure and flow velocity distribution of the flow channel also change correspondingly, so linear scale-up can not be performed on devices with different length. When processing with more fouling and high viscosity product, it is preferred to choose module with shorter length.

Features

  • High flux rates, high filtration capacity
  • Modified hydrophilic PES hollow fiber membrane provides low protein binding, less membrane fouling and easy cleaning

Choose Fiber ID

  • Module with fiber of 0.5mm ID is widely used in most application scenarios to improve mass transfer efficiency.
  • Module with fiber of 1.0mm ID is ideal for products with high cell density or high solid content or high viscosity.
  • Only module with fiber of 1.0mm ID is autoclavable, as steam cannot enter the fiber of 0.5mm ID effectively.

What are the advantages of hollow fiber compared to cassette (flat-sheet) modules?

1. More open flow channels and relatively lower shear.
2. High packing density and large surface area per module enable a compact system footprint with minimal hold-up volume.
3. Robust handling of challenging feed streams, including high solids content or viscosity.
4. Suited for large-volume, high-flow continuous processing in drug manufacturing, such as for insulin and animal vaccines.

What are the applications of hollow fiber technology?
  • Concentration and buffer exchange of viral vaccines
  • Concentration and diafiltration of Cell and Gene Therapy (CGT) products
  • Purification, concentration, and buffer exchange of mRNA products
  • Biomass harvesting from bacterial fermentation, and clarification/removal of cell debris from cell culture lysates
  • Cell retention in perfusion culture (ATF system)
What materials and cut-offs are available for Cobetter ultrafiltration hollow fiber?

Material: m-PES.
Ultrafiltration hollow fiber filters are available with cut-offs ranging from 3–750 kDa.
Microfiltration hollow fiber filters are available in pore sizes ranging from 0.1–0.65 µm.

Can Cobetter‘s hollow fiber modules be sterilized?
