Abstract:
The present disclosure relates to hollow fiber tangential flow filters, including hollow fiber tangential flow depth filters, for various applications, including bioprocessing and pharmaceutical applications, systems employing such filters, and methods of filtration using the same.

Claim (Index 17):
A method of harvesting a bio material from a bioreactor system comprising a process vessel fluidly connected to a tangential flow depth filtration (TFDF) unit having a feed/retentate channel and a filtrate channel, comprising the steps of:\n flowing a culture medium through the feed/retentate channel of the TFDF unit, whereby a fraction of the culture medium passes into the filtrate channel; returning fluid from the feed/retentate channel to the process vessel; and collecting fluid from the filtrate channel; wherein the TFDF unit comprises a thick-walled hollow fiber formed from at least one polymer and comprising a porous wall, the thick-walled hollow fiber having a density of about 53% of the density of an equivalent solid volume of the at least one polymer, the porous wall defining a lumen that is in fluid communication with the feed/retentate channel.
