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, and 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 contrary, due to the significant pressure drop difference between inlet and outlet that exists 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 lengths. When processing with more fouling and high viscosity products, it is preferred to choose a module with shorter length.

Features

  • Aseptic Process Assurance: For processes where bioburden cannot be sufficiently reduced using a 0.2 μm sterilizing-grade filter, heat sterilization hollow fiber filter can ensure aseptic operation
  • Reusable Design: The membranes can be cleaned and reused for multiple times, reducing overall operating costs
  • High Temperature and Pressure Resistance: Supports steam-in-place or autoclave

Applications

  • Yeast, oncolytic bacteria, and other cell harvesting/purification
  • Polycystic liposome concentration and diafiltration
  • Continuous cell perfusion culture
  • Aseptic concentration of lentivirus and adenovirus vaccines
  • Aseptic purification of monoclonal antibodies and recombinant proteins

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)
