    摘要: Disclosed herein are systems and methods for purifying aqueous solutions. For example, disclosed herein are flexible membrane distillation systems comprising one or more stages stacked on top of each other, wherein each stage comprises: a feedwater layer; a membrane distillation layer; a distillate layer; and a thermally conductive layer. The systems further comprise substantially impermeable top surface, bottom surface, and perimeter. Each feedwater layer is independently receives a portion of a contaminated aqueous solution (a feed solution). Each feedwater layer further receives heat from a heat source to distill at least a portion of the feed solution through the membrane distillation layer, thereby producing a distillate in the distillate layer. Distilling said portion of the feed solution through the membrane distillation layer purifies said portion of the feed solution to produce a purified aqueous solution, which is condensed in the distillate layer to form a condensate.

    摘要: The present invention relates to apparatuses for use in electrophoretic separation of macromolecules and/or cells, and in which circulating buffer streams are not required for the electrophoretic separation of macromolecules and/or cells. In certain embodiments, the electrophoretic apparatus disclosed herein comprise a sample chamber and a harvest chamber separated by a size-exclusion membrane; non-circulating buffer chambers flanking each respective sample chamber and harvest chamber, wherein each buffer chamber is separated from each respective sample chamber and harvest chamber by an ion-permeable membrane (restriction membrane), and wherein the buffer chambers are sealed and contain a buffer solution; and an electrode positioned in each buffer chamber. Also disclosed are related methods of using the electrophoretic apparatus disclosed herein.

    摘要: A biological fluid separation device adapted to receive a biological fluid sample having a first portion and a second portion is disclosed. The device includes a housing having a first chamber having a first chamber inlet for receiving the biological fluid sample therein and a first chamber outlet. The housing has a second chamber having a second chamber inlet and a second chamber outlet, and a separation member separating at least a portion of the first chamber outlet and the second chamber. The separation member is adapted to restrain the first portion of the biological fluid sample within the first chamber and to allow at least a portion of the second portion of the biological fluid sample to pass into the second chamber. An actuator, such as a vacuum source, draws the biological fluid sample into the first chamber and the second portion into the second chamber.

    摘要: A system for manufacturing a membrane filter is provided. The system includes a radiation source operative to emit radiation that contacts discrete portions of a filter substrate so as to facilitate the formation of openings within the filter substrate, and a collimator disposed between the filter substrate and the radiation source and operative to restrict some of the radiation from contacting the filter substrate.

    摘要: A method for automated processing of a blood product, the method comprising providing a reusable separation apparatus controlled by a microprocessing unit, said apparatus configurable with settings and configured to associate with a disposable circuit comprising a separator and in communication with a source blood product having a first concentration and first volume. The apparatus and disposable circuit are configured to flow the source blood product into an inlet of the separator and separate supernatant of the source blood product from a first outlet of the separator into a filtrate container. The apparatus and disposable circuit are also configured to separate platelets and remaining supernatant from a second outlet of the separator into a retentate container, wherein the platelets and remaining supernatant in the retentate container have a second concentration greater than the first concentration and second volume less than the first volume.
