Hollow-fiber bioreactor
A hollow-fiber bioreactor is a 3-dimensional cell-culturing system based on hollow fibers, which are small, semi-permeable capillary membranes arranged in a parallel array with a typical molecular weight cut-off (MWCO) range of 10–30 kDa. These hollow-fiber membranes are often bundled and housed within tubular polycarbonate shells to create hollow-fiber bioreactor cartridges.
