| 20110215051 | METHOD AND APPARATUS FOR THE FILTRATION OF BIOLOGICAL SOLUTIONS - A system, method and device are disclosed for bio-processing a feed stream and providing a constant output by operating a continuous single-pass tangential-flow process. The single-pass process provides high conversion concentration while operating at relatively low feed flow rates, and the process can also be used to provide constant output diafiltration. | 09-08-2011 |
| 20100133185 | METHOD AND APPARATUS FOR THE FILTRATION OF BIOLOGICAL SOLUTIONS - A system, method and device are disclosed for bio-processing a feed stream and providing a constant output by operating a continuous single-pass tangential-flow process. The single-pass process provides high conversion concentration while operating at relatively low feed flow rates, and the process can also be used to provide constant output diafiltration. | 06-03-2010 |
| 20090277833 | TANGENTIAL FLOW FILTRATION SYSTEM - A system, method and device are disclosed for bio-processing a feed stream providing a constant output by operating a continuous single-pass tangential-flow process. Embodiments are operated without large circulation pumps. Other embodiments use components which can be disposed after a single use. The system, method and device can also be used to provide constant output diafiltration. | 11-12-2009 |
| 20090145845 | METHOD AND APPARATUS FOR THE FILTRATION OF BIOLOGICAL SAMPLES - A separation module and method are disclosed for processing a liquid sample and providing high conversion by operating a single-pass tangential-flow process without a recirculation loop. In one embodiment, the separation module includes three reservoirs and has at least one long, thin channel with a large ratio of channel membrane area to: channel void volume; volume of a sample feed reservoir; and volume of the feed sample. In another embodiment, the separation module includes two reservoirs and a hydrophobic vent. The single-pass process provides high conversion while operating with relatively low pressure sources. | 06-11-2009 |
| 20080245733 | METHOD AND APPARATUS FOR THE FILTRATION OF BIOLOGICAL SOLUTIONS - A system, method and device are disclosed for bio-processing a feed stream and providing a constant output by operating a continuous single-pass tangential-flow process. The single-pass process provides high conversion concentration while operating at relatively low feed flow rates, and the process can also be used to provide constant output diafiltration. | 10-09-2008 |
